Two new subsystem reference designs from Maxim Integrated Products provide very accurate, low-power optical proximity sensing and enhance distributed control with a compact digital-input hub. The ...

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 ...

Manufacturers of proximity sensors are among those showcasing new products at the Design & Manufacturing Midwest show, Sept. 22-24, in Rosemont, IL. Sensor manufacturers include Balluff, Banner ...

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 ...

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.
