Automotive optical sensing functions, from auto-dimming rearview mirrors and rain / light tunnel (RLT) sensing to ambient light measurement, rotary encoders, and reflective switches, each demand accurate, repeatable light detection despite wide swings in cabin lighting and temperature.
Vishay's optical sensors and photo detectors provide precise ambient and reflective light sensing, while infrared emitters and reflective switch components enable non-contact encoder and switch designs. Additionally, our Automotive Grade resistors and capacitors filter and condition the sensor's analog output for accurate downstream processing.
