Acceptable values of leakage current must be evaluated in this type of circuit Switch types can be normally open (NO) or normally closed (NC). Image Credit: Fargo Controls, Inc. If the switch is a ...

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 ...

Allegro's ACS37030 and ACS370032 take advantage of the Hall effect and an inductive coil for efficient current sensing with minimal noise. Introduction to Allegro MicroSystems’ ACS37030 and ...

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 ...
