Proximity sensor

Explanation of terms

Standard sensing object Response time

A test detection object that serves as a reference for measuring

basic performance, and which is made of specified materials,

and has a specified shape and dimensions.

• t1: The interval from the point when the standard test object

moves into the detection range of the sensor to the point

when the output turns ON after the sensor activates.

• t2: The interval from when the standard test object moves out

of the sensor detection range to when the sensor output turns

OFF.

Sensing distance Response frequency

The distance from the reference position (reference surface) to

the measured operation (return) when the standard test object

is moved by the specification method.

• The number of detection repetitions that can be output per

seconds when the standard test object is repeatedly brought

into proximity.

• See the accompanying diagram for the measuring methods.

Setting distance Shielded

The distance from the reference surface, which allows stable

use including the effects of temperature and voltage, to the

(standard) test object passage position. This is approximately

70% to 80% of the normal (rated) detection distance.

• With this model, magnetic flux is concentrated in front of the

sensor and the sides of the sensor coil are covered with met-

al.

• The sensor can be mounted by sinking it into the metal.

Proximity sensor

Response difference (response distance difference) Unshielded

With respect the to distance between the standard test object and

the sensor, the difference between the distance at which the sen-

sor activates and the distance at which the sensor resets.

• With this model, magnetic flux is spread widely in front of the sensor

and the sides of the sensor coil are not covered with metal.

• This model is easily affected by peripheral metal objects

(magnetic objects), and thus care must be taken in selecting

the mounting location.

How the dection distance is expressed

In the measurement of the detection distance of the proximity sensor, the reference position and the direction of approach of the detected object are determined as follows.

Round pillar type • Square pillar typeSlot type

Perpendicular detection distanceHorizontal detection distance

Detection area diagram

Expressed as the measured distance from

the reference surface when the standard

test object is made to approach from the ra-

dial direction (perpendicular to the detection

surface).

Expressed as the measured distance from

the reference axis when the standard test

object is moved parallel to the reference sur-

face (detection surface).

This distance varies depending on the tran-

sit position (distance from the reference sur-

face), thus it can be expressed as an

operation point track.

The slot type is frequently used by inserting

a thin metal plate through the slot, and thus

the insertion distance from the reference

surface is measured as shown in the dia-

gram.

Wiring Considerations

Operating Environment

Do not use in an environment where there are explosive, combustible gases.

Important

Item Typical examples

Power supply voltage

Do not use a voltage that exceeds the oper-

ation voltage range. Applying a voltage that

is higher than the operating voltage range,

or using an AC power supply (100 V AC or

higher) for a sensor that requires a DC pow-

er supply may result in explosion or fire.

Load short-circuiting

• Do not short-circuit the load.

Explosion or fire may result.

• The load short-circuit protection function

is functional when the power supply is

connected with the correct polarity and

the power is within the rated voltage.

DC 3-wire model NPN output sensor • DC 2-wire model sensor

• Even with the load short-circuit protection

function, the function will not provide pro-

tection in the event that a load short cir-

cuit occurs and the power polarity is not

correct.

Incorrect wiring

Ensure that the power supply polarity and

other wiring is correct. Incorrect wiring may

cause explosion or fire.

Connection without a load

If the power supply is connected directly

without a load, the internal elements may

explode or burn. Be sure to insert a load

when connecting the power supply.

Do not use in water, rain, or outside.

• Ambient Conditions

In order to maintain reliability of operation, do not use outside the specified tempera-ture range or in outdoor conditions. The proximity sensor has a water resistant structure, however, it must be covered to prevent direct contact with water or water-soluble shaving oil. Do not use in atmo-spheres with chemicals, in particular strong alkaline or acid (nitric acid, chromic acid, or hot concentrated sulfuric acid).

• Explosive atmospheres

Cannot be used in atmospheres where there is a danger of explosion. In this case, it is recommended to use an explosion-proof sensor.

Effect of external electromag-netic field

• The effect within a direct current magnetic field is 20 mT. Do not use at a level higher than 20 mT.

• Sudden changes in the direct current magnetic field may cause incorrect operation. Do not use for applications that involve turn-

ing the direct current electromagnet on and off.

• Do not place a transceiver near the proximity sensor or its wiring, as this may cause incorrect operation.

Design

Sensing Object Material

The detection distance varies greatly depending on the

material of the detected object. Study the characteristic data

in "Effects of object material and size" and select a distance

with sufficient leeway.

• In general, if the

detection object is a

non-magnetic metal

(for example,

aluminum), the

detection distance

decreases.

Size of detected object

In general, if the object is

smaller than the standard test

object, the detection distance

decreases.

• Design the setup for an ob-

ject size that is greater than

the standard test object

size from the "Detected ob-

ject size and detection dis-

tance" graph.

• When the size of the standard test object is as follows,

selecting a distance with sufficient leeway.

Thickness of detected object

• The thickness of magnetic

metal (iron, nickel, etc.)

must be 1 mm or greater.

• However, when the thick-

ness of a coating is

0.01mm or less, a detec-

tion distance equivalent to

a magnetic body can be

obtained. When the coat-

ing is extremely thin and is

not conductive, such as a

vacuum deposited film,

detection is not possible.

• Effects of plating: If the object is plated, the detection dis-

tance will change (see the table below).

Effect of plating (typical examples)(Reference values: Percent with respect to non-plated detection distance)

Mutual Interference

• Mutual interference occurs when a sensor is affected by

magnetism (or static capacitance) from an adjacent sensor

and the output is unstable.

• One means of avoiding interference when mounting prox-

imity sensors close together is to alternate types of differ-

ence frequency. The type table of each model indicates

whether different frequency types exist. Please refer to this

table.

• When proximity sensors with the same frequency are

mounted together in a line or in oppostion, they must be

separated by a minimum distance. For details, refer to

"Mutual Interference" in "Precautions" following each

model.

Power Reset Time

A sensor is ready for detection within 100 ms after turning on

the power. If the load and sensor are connected to separate

power supplies, design the system so that the sensor power

turns on first.

Turning the power off

An output pulse may be generated when the power is turned

off, so design the system so that the load or load line power

turns off first.

Effects of Surrounding Metal

The existence of a metal object other than the detection object

near the detection surface of the proximity switch will affect

detection performance, increase the apparent activation

distance, degrade temperature characteristics, and cause

reset failures. For details, refer to the peripheral metal effects

table in the "Precautions" section for each model.

The values in the table are for the nuts that accompany each

model. Changing the nut material will change the effect of

peripheral metals.

Power transformer

Be sure to use an insulated transformer for a DC power

supply. Do not use an auto transformer (single-coil

transformer).

When using an AC 2-wire / DC 2-wire model, take the follow-

ing points into consideration.

Surge protection

Although the proximity sensor has a surge absorption circuit,

if there is a device (motor, welder, etc.) that causes large

surges near the proximity sensor, insert a surge protector in

the source of the surges.

Effect of leakage current

Even when the proximity circuit is off, a small amount of

current runs through the circuit as leakage current.

(Refer to the "Leakage Current Characteristics".)

For this reason, a small current may remain in the load

(residual load current) and cause load reset failures. Verify

that this voltage is lower than the load reset voltage

(the leakage current is less than the load reset current) before

use.

Counter measures for leakage current (examples)

AC 2-wire model

Connect a bleeder resistance as a bypass for the leakage

current flowing through the load so that the current flowing

through the load is less than the load reset current.

Calculate the bleeder resistance and permitted power from the following equation.

P: Watts of bleeder resistance (the actual number of watts

used should be several times this number)

I: Load current (mA)

It is recommend that leeway be included in the actual values

used. For 200 V AC, use 10 kΩ or less and 3 W (5 W) or

higher, and for 200 V AC, use 20 kΩ or less and 10 W (20 W)

or higher. If the effects of heat generation are a problem, use

a number of watts higher than the number in parentheses ( ).

R ≤Vs

(k Ω) P >Vs2

(mW)10-I R

When using an AC 2-wire model, connect a bleed-

er resistor so that the sensor proximity current is at

least 10 mA, and the residual load voltage when

the proximity sensor is off is less than the load

reset voltage. For the residual voltage

characteristics.

AC power supply voltage Vs


Proximity sensor

DC 2-wire model

Connect a bleeder resistor to bypass the leakage current

flowing in the load, and design for a load current such that

(leakage current) × (load input impedance) < reset voltage.

Calculate the bleeder resistance and permitted power from the following equation.

P: Watts of bleeder resistance (the actual number of watts

used should be several times this number)

iR: Leakage current of proximity switch (mA)

iOFF: Load reset current (mA)

It is recommend that leeway be included in the actual values

used. For 12 V DC, use 15 kΩ or less and 450 mW or higher,

and for 24 V DC, use 30 kΩ or less and 0.1 W or higher.

Load with large current surges

Loads such as lamps or motors that cause a large current

surge* will weaken or damage the open/close element.

In this situation, use a relay.

*E2K, TL-N@Y: 1 A or higher

Mounting

Mounting the Sensor

When mounting a sensor, do not tap it with a hammer or

otherwise subject it to excessive shock. This will weaken

water resistance and damage the sensor. If the sensor is

being secured with bolts, observe the permitted tightening

torque. Some models require the use of washers.

For details, refer to the mounting cautions in "Correct Use" at

the end of the applicable model.

Mounting/removing a DIN rail (example of E2CY)

(Installation)

A Insert the front into the special fitting (accessory) or DIN

rail.

B Press the rear into the special mounting fitting or DIN rail.

• If you are using the special mounting fitting for a side

mounting, secure the fitting to the amplifier unit and then

use M3 screws to mount. Use washers of a diameter of

6 mm or less with the screws.

(Dismounting)

• Removal is easily accomplished without a screwdriver.

While pushing the amplifier unit in the direction of C, lift the

sensor cord plug in the direction of D.

Set distance

The detection distance may vary due to fluctuations in

temperature and voltage. When mounting the sensor, we

recommend a "set distance" installation.

ModelTypes of con-

nectionConnections Description

DC 2-wire

Models

AND (serial

connection)

Keep the number of connected sensors (N) within the range of the following equation.VS - N × VR ≥ Operating load voltage

However, it is possible that indicator lamps may not illuminate correctly and erroroneous pulses (approximately 1 ms) may be generated because the rated power supply voltage and current are not supplied to each individual proximity switch. Verify that this is not a problem before operation.

OR (parallel

connection)

Keep the number of connected sensors (N) within the range of the following equation.N × i ≤ Load reset current

Example: When an MY (24 V DC) relay is used as the load, the maximum number of sensors that can be connected is 4.

AC 2-wire

Models

AND (serial

connection)

TL-NY, TL-MY, E2K-@MY@, TL-T@Y The above proximity sensors cannot be used in a parallel connection. If needed, connect through a relay.

E2E-X@YWith respect to the above proximity sensors, the voltage VL that can be applied to the load when ON is VL = VS - (Output residual voltage × Number of sensors), for both 100 V and 200 V AC.The load will not operate unless VL is higher than the load operation voltage. This must be verified before use.When using 2 or more sensors in serial with an AND circuit, the limit is 3 sensors.(Take care to note the VS value in the diagram at left.)

OR (parallel

connection)

In general it is not possible to use two or more proximity sensors in parallel with an OR circuit.

A parallel connection can be used if A and B will not activate simultaneously and there is no need to hold the load. However, the leakage current will be n×and reset failures will frequently occur.("n" is the number of proximity sensors)

If A and B will activate simultaneously and the load is held, a parallel connection is not possible.If A and B activate simultaneously and the load is held, when A turns ON, the voltages of both A and B fall to about 10 V, and load current flows through A causing random operation. When the detection object approaches B, the voltage of both terminals of B is too low at 10 V and the open/close element of B cannot operate. When A turns OFF again, the voltages of both A and B rise to the power supply voltage and B is finally able to turn ON.

During this time, there are times when A and B both turn OFF (approximately 10 ms) and the load is momentarily restored. In cases where the load is to be held in this way, use a relay as shown in the diagram at left.

Note. When AND/OR connections are used with the proximity switch, the effects of erroneous pulses or leakage current may prevent use. Verify that there are no problems before use.

connection)

Keep the number of connected sensors (N) within the range of the following equation.iL + (N - 1) × i ≤ Upper limit of proximity switch control outputVS - N × VR ≥ Operating load voltage

Note. When an AND circuit is connected, the activation of proximity switch B causes power to be supplied to proximity switch A, and thus erroneous pulses (approximately 1 ms) may be generated in A when the power is turned on. For this reason, take care when the load has a high response speed as incorrect operation may result.

For sensors with current output, a minimum of 3 OR connections is possible.Whether or not 4 or more connections is possible varies depending on the model.

Cable Length

The cable of a built-in amplifier models can be extended to a

maximum length of 200 m with each of the standard cables

(excluding some models).

For separate amplifier models (E2C-T11, E2C, E2J, E2CY,

F2LP), refer to the specific cautions.

Bending the cable

If you need to bend the cable, we recommend a bend radius

that is at least 3 times the outer diameter of the cable (with the

exception of coaxial and shielded cable).

Cable tension limits

In general, do apply a force greater than the values in the

following table.

Note. Note that shielded cable and coaxial cable must not be subjected to ten-sion.

Distinguishing high-voltage wire

Using metal conduit

If a power line lies near the proximity sensor cable, use

independent metal conduit to prevent incorrect operation or

damage.

(Same for DC Models.)

Example of connection with S3D2 sensor controller

Using an S3D2

Operation can be reversed

with the signal input selector

switch on the S3D2.

Connecting to a relay load

Note. The DC 2-wire type has a residual voltage of 3 V. Be sure to check the operating voltage of the relay before use. The residual voltage of the E2E-XD-M1 J-T is 5 V.

Operation can be reversed with the signal input selector

switch on the S3D2.

Operating Environment

Water Resistance

Do not use in water, rain, or outdoors.

Ambient Conditions

1. To maintain operational reliability and product life, use only

within the specified temperature range and do not use

outdoors.

2. The proximity sensor has a water resistant structure,

however, attaching a cover to prevent direct contact with

water will help improve reliability and prolong product life.

3. Avoid using where there are chemical vapors, especially

strong alkaline or acid (nitric acid, chromic acid, or hot

concentrated sulfuric acid) vapors.

Maintenance and inspection

Periodic inspection

To ensure long-term stable operation of the proximity sensor,

together with the control devices, inspect for the following on

a regular basis.

1. Shifting, loosening, or deformation of the detection object

and proximity sensor mounting

2. Loosening, bad contact, or wire breakage in the wiring and

connections

3. Adherence or accumulation of metal powder

4. Abnormal operating temperature or ambient conditions

5. On setting indicator types, abnormal indicator blinking

Disassembly and repair

Do not under any circumstances attempt to disassemble or

repair the product.

Quick failure check

You can conveniently check for failures by connecting the

E39-VA Handy Checker to check the operation of the sensor.
