OPB680 - Slotted Optical Flag Switch Types

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.

Features

  • Phototransistor output.
  • Mechanical switch replacement.
  • Printed circuit board mounting.
  • Enhanced signal to noise ratio.
  • Lever force options.

Product Bulletin OPB680 April 1998 Slotted Optical Flag Switch Types OPB680, OPB680-20 www.datasheet4u.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 the paper edge.
