Proximity sensing based on infrared signal acquisition and processing typically requires two parts to form the optical front end: an infrared LED and an optical sensor. The infrared LED beams infrared ...

Designing with high-fidelity capacitive proximity sensors requires careful consideration of mechanical design, sensor placement/design, and end-application operating environments. Careful evaluation ...

HOW DOES THE CHOICE OF PROXIMITY SENSORS AFFECT THE DESIGN AND OPERATION OF MOTION-CENTRIC AUTOMATION SYSTEMS? Alex • Baumer: Proximity sensors, through their specifications, have a significant effect ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

STMicroelectronics' TMOS sensors handle presence sensing using a 5- to 20-µm passive IR sensor. This provides more accurate results as well as information about the distance rather than just a basic ...

The VCNL3020 proximity sensor from Vishay Intertechnology combines an IR emitter, photo-pin-diode, signal-processing IC, and 16-bit analog-to-digital converter (ADC) in a 4.85- by 2.35- by 0.83-mm ...
