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. The leads are formed to sit flush on a PCB during solder reflow.
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.
