Reflective Object Sensor
OPB702, OPB702D
Features:
Focused for maximum sensiꢀvity
Choice of phototransistor or photodarlington
Low cost plasꢀc housing
Description:
The OPB702 series consists of an infrared Light Emiꢂng Diode (LED) and the choice of a NPN silicon phototransistor
(OPB702) or a photodarlington (OPB702D).
On each sensor, the LED and the phototransistor or photodarlington are mounted side‐by‐side on converging opꢀcal axes in
a black plasꢀc housing. The OPB702 uses type OP505 sensor, the OPB702D uses an OP535 sensor.
Custom electrical, wire, cabling and connectors are available. Contact your local representaꢀve or OPTEK for more
informaꢀon.
