Housing material is electrically conductive. 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. © 2002 Fairchild Semiconductor Corporation Page 1 of 3 5/13/02 PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH QCK3 ABSOLUTE MAXIMUM RATINGS (TA = 25°C unless otherwise specified) Parameter Operating Temperature Stor...
