FEATURES • Choice of phototransistor or photodarlington output
DESCRIPTION The HOA1881 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1881- 011, - 012) or photodarlington (HOA1881- 013) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. The lead wires of minimum length 18.0 in.(457 mm) provide alternate electrical connection when PC board mounting is not possible.
