- 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...
