Proximity sensors, which are designed to detect the presence of nearby objects without any physical contact, have evolved from narrow application in industrial automation systems into broad use. They ...

The coated die-cast housing mounts flush while the thermoset plastic sensing face gives the unit a 20-mm sensing range. Two corner LEDs provide high-visibility status indication. A five-way ...

Available in 8, 12, 18 and 30 mm sizes, the sensors range feature extended sensing distances from 2 mm shielded and 4 mm unshielded for 8 mm sensors to 12 mm shielded and 18 mm unshielded for 30 mm ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...
