The Coil wire-wound for analogue sensing, planar for digital sensing.
Planar (PCB) coils are much more cost effective, custom per application and have a smaller part to part variation.
The Flag (Metal target) is where the eddy current losses are generated.
This can be either part of the customer’s system (shaft, gear, valve…) or it can be custom designed to fit within the customer’s product or within our product. Flags can be insert-moulded or metal injection moulded.
