Photo Electronic Sensors

Jai Balaji Controlgears, India's only manufacturer of ISI marked limit switches has another range of high quality Photo Electronic Sensors. These consist of an emitter, a receiver and an amplifier. Pulsed infra-red light beam is generated by the emitter. This effective beam is reflected either by an object or by a reflector (depending on the type of sensors) and it returns to the receiver. The receiver converts the reflected incoming light signal into electrical signal, and the built-in amplifier signal drives output transistor (either NPN or PNP), which in turn drives an electronic circuit or a relay. Any of the following three types of photo electronic sensors can be used to sense an object based on their sizes and colours.
