A typical inductive proximity sensor has an inductor or what in its sensing head?

Explanation:
Inductive proximity sensors detect metal by the magnetic field created in the sensing head by a coil. That coil, acting as an inductor, is the sensing element: when a metal object comes near, eddy currents in the metal disturb the magnetic field and change the coil’s impedance, and the sensor electronics detect this change to trigger an output. The other parts listed (capacitor, transistor, resistor) are used in the circuitry, not the sensing head itself.
