OPB735 Reflective Object Sensor

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