In inductive proximity switches, a wire coil is charged with an electric current, which is measured. If metal gets close enough to the coil, the frequency changes, which triggers the switch. Find out more below!

Inductive Proximity Switches | ISSC-Kanson Electronics Inductive Proximity Sensors are used to detect metal objects and carbon by using a coil and high frequency oscillator to create an electromagnetic field.
