com Features • Phototransistor output • Mechanical switch replacement • Printed circuit board mounting • Enhanced signal to noise ratio • Lever force options Description The OPB680 consists of an NPN phototransistor and an infrared emitting diode in a molded plastic housing.
The phototransistor has an enhanced low current roll-off which improves contrast ratio and immunity to background irradiance.
A lever arm actuated flag interrupts the light beam, switching the output between states that can readily drive logic gates.
The lever can be actuated by a passing paper sheet without damaging ...
