TT Electronics OPB735 Series Reflective Sensor

TT Electronics - Optek OPB735 Series Reflective Sensor

Search OPB735 Sensors

The TT Electronics OPB735 series reflective sensors consist of an infrared 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 radiation from the IRED only when a reflective object passes within its field of view.

The OPB735 series employs metal can packaged components. The OPB735X series has 4 leads. The OPB735XWZ series has interconnect wires at 12” (304 mm) length UL 1569 approved #28 AWG, stripped and tinned.

Features

Choice of phototransistor or photodarlington output
Unfocused for sensing diffuse surfaces
Low Cost Plastic Housing
Low Profile to Facilitate Stacking
#28 AWG lead wire in 12” ( mm) length

Applications

Non-contact reflective object sensor
Assembly line automation
Machine automation
Machine safety
End of travel sensor
Door sensor

Video Transcript

Could you imagine if everyone you saw came up and poked you just to make sure you were really there? That would be super annoying, at least for me. If your application is like me and wants to see instead of feel objects, then you need the OPB735 series from TT Electronics. The OPB735 series reflective object sensors have an 890 nanometer IR LED paired with an NPN silicon phototransistor or a photodarlington, providing non-contact object detection in applications such as assembly line automation, machine safety, and more.

The emitter and detector sit side-by-side with converging optical axes with a nominal reflection distance of half an inch. The sensors have a non-conductive plastic housing with a low profile to facilitate stacking, and the components inside are hermetically sealed for use in harsh environments. OPB735 sensors are available with 0.9 inch leads or 12 inch lead wires.
