SG243

The SG243 is designed as one kind of reflective sensor that can be used in wide range of applications such as (1)printers; (2)scanners; (3)plotters; (4)auto stampers. Features of this device are:(1)PWB direct mount type; (2)single-sided screw-mount; (3)GAP: 5.0 mm; (4)easy to mount. And this device combines high-output GaAs IRED with high sensitive phototransistor, it is most applicable to paper sensor.
