Introduction The 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 more...
Beam of invisible pulsed modulated infra - red light is produced by emitter. This beam is sensed by receiver at another end (in through beam version) or reflected by object and received by receiver placed near emitter (in diffuse version). When this beam is interrupted by object,more...
