TT Electronics - Optek Technology OPB710 Reflective Object Sensor

Reflective object sensors OPB710, OPB710F, OPB730, and OPB730F feature infrared emission and phototransistor or photodarlington detection, mounted on standard TO-72 headers with encapsulating epoxy and optional filtering to reduce ambient light effects. Suitable for non-contact surface sensing, machine automation, safety applications, and end-of-travel detection, these sensors operate within specific temperature ranges, with defined electrical characteristics. The sensors use gallium arsenide IR LEDs and silicon photoelements, offering reliable, diffuse sensing for industrial automation and safety systems with compact, robust packages.
