Wide Gap Optical Sensor
OPB856Z
Features:
xDesigned for Industrial applications
xThreaded housing (M12 X 1 TH), Nut included
xMolded connectors mates with Molex 03-06-2023 plug.
xEmitter (White) and Senor (Black) housing color coded
Description:
The OPB856 emitter and sensor pair that consists of an LED (935 nm) and a Phototransistor designed to operate
efficiently with each other. They are mounted in a threaded (M12x1TH) color-coded housing. The LED (white)
and the Phototransistor (black) are designed to easily panel mount in through a 0.4724 (12.0 mm) hole. A 12 mm
nut is included for each housing. Both components is designed to electrically mate with a Molex (03-06-2023)
connector.
The OPB856 pair are designed to operate with separation distances between the LED and Phototransistor up to
12 (30.48 cm).
For Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK
