    Category:

    Optical Sensors

    Manufacturer:

    TT Electronics

    Description:

    Each OPB685 and OPB695 series flag switch consists of an infrared emitting diode and a monolithic integrated circuit that incorporates a photodiode, a linear amplifier and a Schmitt trigger. A lever arm actuated flag interrupts the light beam, which switches the output between states that can readily drive logic gates.
