HOA0825 Overview
The HOA0825 series consists of an infrared emitting diode facing an NPN silicon phototransistor encased in a black thermoplastic housing. A slot in the housing between emitter and detector provides the means for mechanically interrupting the emitter beam. The phototransistor switching takes place whenever an opaque object passes through the slot between emitter and detector.
HOA0825 Key Features
