TT Electronics - Optek Technology OPB735A Reflective Object Sensor

The OPB735 series sensors combine infrared LED and a phototransistor or photodarlington in a compact plastic housing, ideal for reflective object sensing in automation. They detect reflective surfaces within a specified field of view and feature hermetically sealed metal can packages for durability and reliability. The series offers models with interconnect wires or leads, suitable for non-contact sensing applications like assembly line automation, machine safety, end-of-travel sensing, and door detection. Their low-profile design facilitates stacking and easy integration into various systems, with voltage and current ratings tailored for robust operation.
