QCK4 PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH

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 dur.
