The SG-105F reflective photointerrupter sensor is a compact and high-performance device designed to be easy to mount on printed circuit boards. It combines a GaAs IRED with a high-sensitivity phototransistor, resulting in a fast response time. This photointerrupter is versatile and can be used for a variety of applications, such as timing sensors, edge sensors, micro floppy disk drives, and liquid level sensors.

The maximum ratings for the SG-105F reflective photointerrupter sensor include a power dissipation of 0.5 W, a reverse voltage of 5 V, an input forward current of 20 mA, a pulse forward current of 100 mA, a collector power dissipation of 0.5 W, a collector current of 100 mA, and an output C-E voltage of 80 V and an E-C voltage of 5 V.
