Optical Switches, Transmissive, Phototransistor Output
(1356 results)Slot type photointerrupters with transistor output are optical sensor modules that utilize a built-in infrared light source and a photodiode separated by an air gap (slot). When an actuator, liquid or other detection object blocks the light source, an output transistor is turned on or off which toggles the applied voltage. Mounting options include chassis, snap-in, surface, free-hanging, and through-hole.
