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 ...
An example is the sensing of a rotary cam position. The oblong shape of the cam dictates use of a sensor able to detect different shapes and sizes. A simple prox sensor merely detects the presence or ...
Of course, many different types of distance measuring sensors exist but not all sensors are the same. Each sensor has its own advantages and disadvantages. At its most basic level, a distance ...
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 ...
DW Series round metal inductive proximity sensors with analog outputs are now available from AutomationDirect in 8mm, 12mm, 18mm and 30mm cylindrical sizes. These reliable DC-powered (10-30V or 15-30V ...
IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...
How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...
