Inductive proximity sensors are non-contact proximity devices that set up a radio frequency field with an oscillator and a coil. The presence of an object can alters this field and the sensor is able ...

2-Wire 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 ...

For anyone unfamiliar with the original project, the circuit detected a vehicle via an inductive loop and was able to perform a task like opening a gate. It now has two independent channels which ...

These connect to an LX3302A inductive sensor IC, which reads the position of the copper slug inside the float. That simplifies the process greatly; [Mark] goes into great detail about the design ...
