DESCRIPTION
The H21A Slotted Optical Switch is a gallium arsenide ™ Opaque housing light emitting diode coupled to a silicon phototransistor in = Low cost aplastic housing. The packaging system is designed to . optimize the mechanical resolution, coupling efficiency, © .035" apertures ambient light rejection, cost and reliability. The gap in the @ High leow housing provides a means of interrupting the signal with an opaque material, switching the output from an “ON” to an “OFF” state.
