OPB857Z - TT

OPB857Z Slotted Optical Switch

OPB857Z is a non-contact optical switch with a NPN silicon phototransistor and infrared Light Emitting Diode (LED) which are mounted on opposite sides of a 0.150” ( 3.8 mm) wide slot. The device upper body is a single molded piece IR transparent plastic that is tinted to reduce ambient light interference and offers water resistance as well as dirt/dust prot.

Features

• Three wires for economy in electrical connection
• Water resistant, no optical openings in upper plastic body
• Internal narrow aperture for high motion resolution Description: OPB857Z is a non-contact optical switch with a NPN silicon phototransistor and infrared Light Emitting Diode (LED) which are mounted on opposite sides of a 0.150” ( 3.8 mm) wide slot.
