Impedance The total opposition alternating current.The symbol for
impedance “Z. Inductive reactance directly proportional to
frequency (f) and inductance (l).
Inductive Proximity Switch type sensing switch that uses electromagnetic coil
to detect the presence metal object without coming into
physical contact with it.
