The OPB702 series consists of an infrared Light Emitting Diode (LED) or red Visible Light Emitting Diode (VLED) and the choice of a NPN silicon phototransistor (OPB702), a photodarlington (OPB702D) or a base-emitter resistor for low light suppression (OPB702R, OPB702RR).

On each sensor, the LED and the phototransistor, photodarlington or base-emitter resistor are mounted side-by-side on converging optical axes in a black plastic housing. The OPB702 uses type OP505 sensor, the OPB702D uses an OP535 sensor and the OPB702R, OPR702RR uses an OP705 sensor.

Custom electrical, wire, cabling and connectors are available. Contact your local representative or OPTEK for more information.
