Vishay Intertechnology IR sensor modules
Summary
Unlike high sensitivity fixed-gain IR sensor modules that require attenuators like dark panels, apertures, and sunshades to protect them against sunlight — adding to overall solutions costs — the controlled sensitivity of the Vishay Semiconductors devices released today allows them to operate in full sunlight without unwanted pulses. In addition, for short range presence and proximity applications, the sensors reduced sensitivity eliminates the need for extremely low emitter forward currents, which can lead to unstable intensity outputs. Featuring a fast 260 μs reaction time, the TSSP93038DF1PZA and TSSP93038SS1ZA deliver long range proximity sensing (1m with TSAL6100 at 100 mA). The devices are ideal for sensing the distance to objects for toys, drones, robots, and vicinity switches; presence detection for traffic control lights and parking lot, gateway access, and water level sensors; and light barriers for sports racing and lawnmower robots. They may also be used as reflective sensors for hand dryers, towel or soap dispensers, water faucets, toilets, vending machine fall detection, and security and pet gates.
