H21A1 OPTO INTERRUPTER SENSOR

H21A1 OPTO INTERRUPTER SENSORDescription The H21A1 Opto Interrupter is a high performance slotted optical switch designed for non contact object sensing. It consists of a gallium arsenide infrared emitting diode (IRED) and a high sensitivity NPN silicon phototransistor mounted in a rugged, opaque plastic housing. The 3mm slot allows for a mechanical actuator, such as an encoder wheel or a limit vane, to pass between the emitter and detector, "interrupting" the light beam to
