HOA-1870 sensor equivalent, transmissive sensor.
* 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 .
in which maximum position resolution is desired. Both emitter and detector have a 0.006 in.(0.152 mm) x 0.040 in.(1.02 m.
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.
