Product Description
Product Overview
The H21A_ and H22A_ series are single-channel optoelectronic slotted interrupter switches featuring a Gallium Arsenide infrared emitting diode and an NPN silicon phototransistor. Designed for high resolution, efficient coupling, and ambient light rejection, these switches operate by interrupting infrared light transmission with opaque objects, switching the output from 'ON' to 'OFF'.
