Optical Proximity Switch with Infra-Red Type Sensor is useful for counting and position sensing applications in pharma, food, paper, plastic and automobile industry. The Proximity Switch is provided with infra-red type sensors that incorporate advance technology. The Proximity Switch has a distinct advantage of higher sensing distance over inductive and capacitive type of switches. Optical Proximity Switch with Infra-Red Type Sensor works more reliably in noisy electromagnetic radiation environment.
