TT Electronics OPB735 Series Reflective Sensors

TT Electronics OPB735 Series Reflective 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. These devices employ hermetically sealed metal can packaged components. The OPB735X series has 4 leads. These reflective sensors have interconnect wires at 12” (300 mm) length, UL 1569 approved, #28 AWG, stripped and tinned. These features make the OPB735 series ideal for applications requiring precise and reliable reflective object detection.

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.
