Reflective Object Sensor OPB702, OPB702D, OPB702R, OPB702RR Features: * Focused for maximum sensitivity * Choice of phototransistor, photodarlington or base-emitter Product Photo Here resistor * Low cost plastic housing Description: 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-byside 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.

RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. d is the distance from the assembly face to the reflective surface. Measured using Eastman Kodak gray card. The white side of the card is used as a 90% diffuse reflectance surface.
