Inductive Loops

An alternative configuration to the inductive head type power supply is a stationary loop, which encircles the shaft and transfers power to a second loop located around shaft, or to a power pickup module (part IP2) carried on the shaft clamping kit strapping.

The stationary loop will usually be attached to the IL2 interface (loop matching) module. If the connecting cable is less than 2 metres connection can be made directly to the loop and the IL2 dispensed with.
