2-Wire DC circuitry typically includes a diode bridge in series with the sensor, allowing functionality either as NPN or PNP in a DC circuit. Acceptable values of leakage current must be evaluated in ...
Electrical connections for hall effect proximity sensors can be fixed cable, connector(s), and terminals. There are a number of features that may be important to consider when selecting hall effect ...
[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.
