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 ...
Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...
