Optek / TT Electronics OPB735 Reflective Object 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 infrared emitting diode only when a reflective object passes within its field of view. Optek / TT Electronics OPB735 Reflective Object Sensors include OPB735X sensors with four leads and OPB735XWZ sensors with 300mm interconnect wires. Applications include non-contact reflective object sensors, assembly line automation, machine automation, machine safety, and more.
