Silicon Labs SI1102-A-GM

19.7"（50cm）1.6'2.2V ~ 5.25V

Overview

The SI1102-A-GM is a high-performance (0–50 cm) active proximity detector. Because it operates on an absolute reflectance threshold principle, it avoids the ambiguity of motion-based proximity systems.The SI1102-A-GM consists of a patented, high-EMI immunity, differential photodiode and a signal-processing IC with LED driver and high-gain optical receiver. Proximity detection is based on measurements of reflected light from a strobed, optically-isolated LED. The standard package for the SI1102-A-GM is an 8-pin ODFN.Applications:• Proximity sensing• Photo-interrupter• Occupancy sensing• Touchless switch• Object detection• Handsets• Intrusion/tamper detection
