HOA-1870 - Transmissive Sensor

General Description

The HOA1870 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1870- 031) or photodarlington (HOA1870- 033) encased in a black thermoplastic housing.

Detector switching takes place whenever an opaque object passes through the slot between emitter and detector.

Key Features

  • Choice of phototransistor or photodarlington output.
  • Accurate position sensing.
  • 0.070 in. (1.78 mm) slot width.
  • 18.0 in. (457 mm) min. 22 AWG UL 1007 wire leads INFRA--7.TIF.

HOA1870 Transmissive Sensor FEATURES • Choice of phototransistor or photodarlington output • Accurate position sensing • 0.070 in.(1.78 mm) slot width • 18.0 in.(457 mm) min. 22 AWG UL 1007 wire leads INFRA--7.TIF DESCRIPTION The HOA1870 series consists of an infrared emitting diode facing an NPN silicon phototransistor (HOA1870- 031) or photodarlington (HOA1870- 033) encased in a black thermoplastic housing. Detector switching takes place whenever an opaque object passes through the slot between emitter and detector. A minimum of 18.0 in.(457 mm) lead wires provides alternate electrical connection when PC board mounting is not possible. This device is ideal for use in applications in which maximum position resolution is desired. Both emitter and detector have a 0.006 in.(0.152 mm) x 0.
