Summary

Positional Sensors: Inductive Proximity Switch
Detects the presence of metallic objects (non-contact) via changing inductance
Sensor has 4 main parts: field producing Oscillator via a Coil; Detection Circuit which detects change in the field; and Output Circuit generating a signal (NO or NC)
