This circuit is designed to provide delayed relay switching action at power on. The delay is a function of the time constant produced by the combination of R1 and C1. At power on, C1 charges slowly ...

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 ...

Sensor manufacturers use three common methods to combat this problem: time-based filtering, lowpermeability core and coil systems, and air-coil systems. Time-based filtering installs a time-delay ...
