PHOTOELECTRIC SENSORS WITH BACKGROUND SUPPRESSION

OPERATING PRINCIPLEPhotoelectric sensors with background suppression function by using the angle of incidence, rather than the amount, of reflected light. The light pulse from the emitting diode leaves the optical system as a focused, almost parallel, light beam. On meeting an object in its path, part of the beam is dif-fusely reflected, and in turn, part of this reflected light falls on the PSD (Position-Sensitive Device) housed in the same sensor (Fig. 1). Depending on the distance of the target from the device, the light falls on a particular spot of the PSD, and a corresponding reception signal is emitted, indicating that an object is present at a certain distance from the device. The analyzing circuit compares the signal received with the preset operating distance (adjusted by means of the built-in potentiometer), and, if the distance of the object is less than, or equal to, the preset operating distance, the output is switched. Contrary to an energetic diffuse sensor, the operating distance depends only to a very small extent on the target size or color, or on the nature of its surface. The object can therefore be easily discerned, even against a light background. These devices are not suitable for objects having shiny surfaces.

AvAILABLE MODELSThe present range of photoelectric sensors with background suppression comprises cylindrical as well as rectangular models of various sizes, thus providing the user with a considerable choice.

INTRODUCTION

www.contrinex.com �

The devices feature:− Large setting ranges (adjustable by means of a built-in potentiometer)− Virtually negligible blind zone− Operating distance independent of target color, shape and surface structure− High switching frequencies− High degree of protection (IP 67)

DEvICES WITH ANALOG OUTPUTThe background suppression product range includes devices with analog output with excellent white-gray characteristics. These feature a large sensing range, excellent temperature stability and an outstanding repeat accuracy. The sensing range, as with classic background suppression mod-els, is furthermore independent of the target color and surface structure. Since intermediate digitali-zation has been dispensed with, the resolution of these sensors is virtually unlimited.

fIBERSThe range furthermore includes synthetic fibers with background suppression for axial and lateral sensing. These fibers recognise position and thickness differences of only 0.1 mm and detect targets as small as 0.15 mm2 as well as wires/threads with diameters from 0.1 mm.

For suitable amplifiers, please consult our catalog "Fiber-optic solutions".


MAIN fEATURES− Sensing range from 10 ...100 mm− Excellent resolution− Excellent temperature stability− Voltage output of 0 ... 5 V− Operating distance independent of target color and surface structure− Bandwidth of 100 Hz− Glass lens, easy to clean− High degree of protection: IP 67

CONNECTIONSwitches with 2 m PVC cable 3 x 0.34 mm2 are standard. Other cable types or lengths are available on request.
