OPB735-Optek-Product OPB735-Optek-Product-2

The OPB735 series sensors consist of an infrared light emitting diode and an NPN silicon phototransistor or photodarlington,
encased side-by-side on converging optical axes in a black thermoplastic housing.

The detector responds to light from the IRED only when a reflective object passes within its field of view.

The OPB735 series employs hermetically sealed metal can packaged components.


  • Choice of phototransistor or photodarlington output
  • Unfocused for sensing diffuse surfaces
  • Non-conductive plastic housing
  • Low profile to facilitate stacking
  • #28 AWG lead wire in 12” ( 300 mm) length


  • Non-contact reflective object sensor
  • Assembly line automation
  • Machine automation
  • Machine safety
  • End of travel sensor
  • Door sensor
  • Compatible with Honeywell
    HOA1180 and HOA2498
