OPB856Z Features:  Designed for Industrial applications  Threaded housing (M12 X 1 TH), Nut included  Molded connectors mates with Molex 03-06-2023 plug.  Emitter (White) and Senor (Black) housing color coded Description: The OPB856 emitter and sensor pair 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).
