    Products Detail

    These optical flag switches are designed as mechanical switch replacements, featuring an infrared emitter and phototransistor. They use a lever arm actuated flag to interrupt the light beam, switching the output to drive logic gates. The devices can be actuated by passing a paper sheet without damaging the edge. OPB680-20 offers increased lever operating force for heavy-duty applications like door sensing, while OPB690Z allows snap mounting into materials with a rectangular opening. Custom lever arms, spring torques, electrical options, and connectors are available.

    Key Features

    • Phototransistor output
    • Mechanical switch replacement
    • Enhanced signal to noise ratio
    • Printed PCBoard mounting
