TT Electronics - Optek Technology OPB735C Reflective Object Sensor

The OPB735 series sensors comprise an infrared LED and an NPN silicon phototransistor or photodarlington in a compact, black thermoplastic housing. Designed for reflective object detection, they respond to objects passing within their focused field of view. Suitable for non-contact sensing and automation applications, these hermetically sealed sensors feature low-profile design and 12-inch (300 mm) #28 AWG lead wires. Available variants include transistor and darlington outputs, with reliable performance for machine safety, end-of-travel sensing, and assembly line automation. Custom options are also accessible through TT Electronics.
