QCK4 - PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH

Description

The QCK3/QCK4 is a slotted opticalswitch designed for surface mount applications where extreme temperatures are experienced during solder reflow.

The switch consists of a GaAs LED and a silicon photodarlington facing each other across a.157" (4.0 mm) gap.

Features

  • Unique single piece housing designed to reduce cost.
  • High temperature housing material to withstand extreme temperature.
  • Shipped in plastic tubes for protection of leads and to feed automatic placement equipment.
  • Sensor package is infrared transparent and tinted to attenuate visible light. © 2002 Fairchild Semiconductor Corporation Page 1 of 3 5/13/02.
