Description:
H22A1High sensitivity opto-interrupter with 0.35”apertures.The H22A slotted optical switch is a gallium arsenide light emitting diode coupled to a silicon photodarlington in a plastic housing.The packaging system is designed to optimized the mechanical resolution,coupling efficiency,ambient light rejection,cost and reliability . The gap in the housing provides a means of interrupting the signal with an opaque material,switching the output from an "ON to an OFF" state.
