Slotted Optical Flag Switch OPB850A, OPB850-1Z Features: Snap into PCBoard mounting Transistor output Product Photo Here Mechanical switch replacement Four 18 (457 mm) 26 AWG, UL wires for electrical connections Choice of phototransistor or Rbe phototransistor output Description: 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. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
