Slotted Optical Flag Switch

Each OPB850A Switch has a NPN Phototransistor coupled with a 940 nm gallium arsenide Infrared Emitting Diode in a molded plastic housing. Each OPB850-1Z has a Rbe Phototransistor coupled with an 880 nm gallium arsenide Infrared Emitting Diode in a molded plastic housing. An actuated lever ARM flag interrupts the light beam, which switches the Transistor output between states that CAN readily drive Logic Gates These devices are designed to replace conventional mechanical limit switches where long life and reliability are critical. The switches are designed to easily snap mount into a 0.036 inch (0.914 mm) 20 gage thick material with a rectangular opening of 0.315 x 0.472 (8.0 mm x 12.0 mm). Minor differences exist in the package between the OPB850A and OPB850-1Z (see drawings below). The cable exits the package in different locations. By Optek Technology, Inc.
