It all began in 1972 when the first Jayashree

Product an Electrodynamic Speed Switch was

patented. The dream of import substitution was

realized in those first euphoric days. This laid the

technological foundation for the other products.

Expanding from a beginning of one small product

a new product was developed practically every

year. New associate companies were formed over

the period to produce different types of products.

Realsing the growing importance of electronics in

industrial controls a range of electronic control

devices was introduced in the Eighties wherein

'JAYASHREE' pioneered the development of

Inductive Proximity Switches as also Electronic non

contact Speed Switches. In order to cope up with

the demand for these products, Jayashree Electron

came in to existence in the year 1987 to develop

and produce Electronic products.

EXPLANATION OF TECHNICAL TERMS

SENSING DISTANCEThis is the distance between the target and the sensing face at which the switch operates. This is usually specified considering MS material as target.

REPEAT ACCURACY This is the accuracy whereby the switch operates repeatadely at given stable operating conditions. For Inductive Switches, the accuracy is better than +/- 0.2 %

RESPONSE TIMEThis is the time by which the switch changes its state after target enters the sensing zone. For DC switches the response time can be as low as 0.3 milliseconds but for AC switches this is around 70 milliseconds due to external load parameters.

FLUSH MOUNTINGSwitches referred to as Flush type can be mounted inside metal body and have only frontal electromagnetic field. The sensing distance in this case is limited to 0.7 times the sensing distance specified for a non-flush type switch.

NON-FLUSH MOUNTINGThese type of switches should necessarily be mounted with sensing zone in metal free area.

SUPPLY VOLTAGEFor DC switches, a filtered and ripple-free regulated power supply should be used and for AC switches the supply should be EMI free as far as possible.

SWITCHING HYSTERISISThis is the differential between “Switch ON” and “Switch OFF” point of the switch. This is adjusted within limits of 5% to 15% of the specified sensing distance.

OUTPUT LOGICThe output switching element (either a Transistor or Thyristor) can be normally in Closed (ON) or Open (OFF) condition.The output logic has to be very carefully selected considering the application requirement.For specific applications, the Inductive switches above M24 size are available with built-in electromagnetic relay to give a potential free output contact for switching external loads. The output logic in this case can be NO, NC or CO (Change-over) type. Switches with a specific output logic such as Latched type, Oscillator type are available on request.

LOAD CURRENTThis is the maximum current, which the switch can either sink from or source to the external load.

APPLICABLE STANDARDSFollowing standards are being followed for design & manufacture : l IS-13947 l UL-508

l EN 61000-3-3 & EN 61000-3-4l CSA 22.2 NO. 14-95

TYPES OF OUTPUT CONNECTIONS

3-Wire & 4 Wire DCSW 3051 / 4051 / 5051 / 6051 / 7051 These switches operate on DC voltages from 5 volts to 240 volts. Standard models operate on 10-30 V DC and can be used with Logic Circuits, Counters or to drive Relay Coil directly. The output of these switches can be either PNP or NPN or both. With PNP output, the switching is in the sourcing mode and the load must be connected between the Output and the Negative of the supply. Conversely, with NPN output the switching is in sinking mode & the load must be connected between the output & the positive of the supply.All 3 wire & 4 wire DC switches are internally protected against Inductive voltage peaks, Spurious line pulses, Reverse polarity & Short circuit conditions.

PRINCIPLE OF OPERATIONSeries SW 405 Inductive Proximity Switches, available in varied shapes & sizes, are a reliable option for applications in Machine tools, Foundries, Rolling mills, Automobiles, Textiles, Pharmaceuticals and Material Handling systems.This type of switches work on ‘Damped Oscillator’ principle. During operation a frontally radiated electromagnetic oscillating field is projected from the sensing face. Any electrically conductive material entering this field causes damping of the oscillations.This change is detected by the in-built sensitive & reliable electronic circuit and is converted into an effective output signal.

APPLICATIONSFor Counting / Position Sensing of various objects in

Bulk Material handingAutomobileSteel PlantsFertilizerCementEngineering Industries

SENSING OBJECT MATERIALThe standard Inductive Proximity Switches can sense any metallic (electrically conductive) object. However, we have special type of switches to sense either only ferrous objects or sense only non-ferrous (Cu, Al etc.) objects. The details for the non-ferrous sensing switches are described elsewhere.

SENSING ZONEthis switch has a dome shaped electro-magnetic field present in front of the sensing area. The switch will sense the object entering into this domain.

SENSING DISTANCE (Sn)This is the distance between the target and the sensing face at which the switch operates. This is usually specified considering M.S. as target material.

CORRECTION FACTORTargets other than MS actuate the Inductive Switches at relatively less distance with correction factor as given below. However this criteria is not applicable to special “Non-ferrous sensing models”.

NON-FERROUS INDUCTIVE SWITCHESAll standard inductive switches sense presence of any metal but will offer stated sensing distance only for ferrous materials like MS. The type SW 4051-NF is specially developed to sense only non-ferrous metals such as Copper, Aluminium, Gold, Tin, Zinc etc. The biggest advantage of this type of switch is that the non-ferrous objects are sensed from larger distances as compared to standard models. These switches are available in M18 and above sizes. The other operating features are same as those of standard 3 wire DC Switches.

HIGH PRESSURE SWITCHESSpecial high pressure type Inductive Proximity Switch has been developed for direct use in a Hydraulic cylinder.The switch construction is sturdy and is rated for pressure upto 500 bar.These switches are also available in connector version for easy replacement.

Switches with Built in Connector

INDUCTIVE

INTRODUCTIONThe Series SW 505 Capacitive Proximity Switches are designed for sensing wide range of materials. These switches give a superior performance for detection of various non-metallic objects where Inductive type switches can not function.The major applications of Capacitive Switches include sensing of;

Liquid level

Plastic granules & parts

Sand / Bulk Material Level

Food / Grain / Confectionary

Paper & rubber

Glass bottles / Tins in packaging

WORKING PRINCIPLEThe switch works on the principle of resonant oscillator circuit. A pair of brass/copper disc form the electrodes of a capacitor & the object acts as a dielectric media. The change in capacitance value, due to presence of object, is sensed by a precision integrated circuit. An effective output signal is generated at a preset value of capacitance.

CONSTRUCTIONThese are offered in tubular threaded housing from size M12 to M80. The enclosures are made of Brass, Stainless Steel or Engineering Plastics. Special shapes, Teflon housings are provided against requirements.Standard models are provided with an integrated 2 meter long cable. Connector type versions are available with built-in male connectors.

SENSING DISTANCEThe nominal sensing distance of any size of switch is specified with Water as standard object and tested at 25°C.Depending upon the material of the object to be detected, the distance will vary. The sensitivity of the sensor is adjustable with a trimpot provided usually on the rear side of the sensor. Typical Sensing distance chart for a M30 size sensor, for different objects is shown in Fig-1.

EFFECT OF AMBIENT CONDITIONS ON SENSITIVITYThe sensing distance is affected by change in ambient temperature, humidity, size and material of the object.

CAPACITIVE Type : SW 5051 - DC / SW 5055 - AC

INTRODUCTIONThe Optical Proximity Switches are a reliable solution for automation where other Proximity Switches have limitations.These are Infra-red type sensors incorporating advance and reliable technology.These switches have a distinct advantage of higher sensing distance over Inductive and Capacitive type of switches.These can work more reliably in a noisy electro-magnetic radiation environment. As an infra-red wavelength light source is used, it is immune to visible light interference.

APPLICATIONSThese switches are very useful for counting and position sensing applications in Pharma, Food, Paper, Plastic & Automobile industry. They also work effectively in level sensing applications for solids, grains, sand, ice and other non-metallic bulk material. Some typical applications are -

Component positioning sensing in Electronic IndustryCounting of bottles, Jars, Containers etc.Glass sheet position sensingFor security & safety in Machine Tools, Presses etc.Color sensing applications

PRINCIPLE OF OPERATIONThese switches incorporate an Infra-red transmitter & receiver device housed in a single enclosure or separate enclosures. The precision pulsed transmitter beam is interrupted or reflected by the object. The advanced electronic circuit generates an effective output signal when the object is sensed.

l

l

l

l

l

Thru-Beam (TB) type switches have separate transmitter & receiver. The object is sensed when the beam is interrupted.Diffuse Scan (DS) type switches have both transmitter & receiver in the same enclosure.The closely focussed beam is reflected back by the object.Retro-Reflective (RR) type switches use a special reflector to reflect back the beam. When an object interrupts the beam, an output signal is generated. These models have greater sensing distance compared to DS type. The receiver does not consider any reflections from other objects or sources.

EXPLANATION OF TECHNICAL TERMS

STANDARD OBJECTThe sensing distance specified for DS switch is considered with a white object having minimum 90% reflectivity.

SENSING DISTANCE This is the maximum specified range of a sensor measured at 25°C using a standard object.

CONSTRUCTIONThese switches are offered in tubular metallic, acrylic & plastic enclosures. Standard models are available with integrated 2-meter long cable. Switches with built-in (Male) connectors (International M8/M12 size) for quick connections are also available.

SWITCHES WITH OPTICAL FIBRE Special model of Optical Switches are available with an integrated Optical Fibre cable for flexible mounting and for sensing miniature objects / high temperature objects.This switch is of through-beam type and is available in H type enclosures.

The series SW 305 Ultrasonic Proximity Switches are ideally suitable for level monitoring applications. The Ultrasonic Sensors are available in different enclosures to detect various types of objects.

The sensing range covers from 0.2 m to 20 meters. The output signal is either in the form of a switching signal or a linear output current or voltage signal. These sensors have the ability to perform in dry and dusty environments. The performance of these sensors is not affected by the presence of impeding materials like Ash, Soot, and Sawdust etc.

These sensors are immune to electrical noise level generally present in the typical industrial environment.

WORKING PRINCIPLE

These switches incorporate a precise and delicate piezo Ceramic Ultrasonic transducer pair. The sensors are available in open as well as sealed type transducers.

The transmitter sends a modulated Ultrasonic Signal, which is reflected by the object.

A microprocessor-based circuit precisely measures the time taken to travel the distance from object to sensor. Effective output signal (either linearly varying or switching type)

is generated depending upon application.
