The OPB680 is an Optical Flag Switch that consists of an infrared emitting diode in a molded plastic housing. The phototransistor has an enhanced low current roll-off that improves contrast ratio and immunity to background irradiance. A lever arm actuated flag interrupts the light beam and switches the output between states that can readily drive logic gates. This can be actuated by passing a paper sheet without damaging the paper"s edge. Insertion into the punched side of metal is recommended.
