Variable air gap touchless sensor.

The custom touchless variable air gap sensor creates immunity to radial and axial play on mobile shafts where significant misalignment results in poor operational performance and labour intensive maintenance programmes. It complements our PS2P-LIN and PS2P-CON series of air-gap non-contact linear and angular position sensors.

A round or arc magnet (where 360º rotation angle is unnecessary) is attached to rotating parts of kit, such as boom loaders, skid steer buckets and hitch arms, and the electronics module to the chassis (or vice versa).

PS2P-ARC models

Here, Piher separates the magnet from the electronics module.
As an absolute sensor it will not loose the values even after a power failure.

All Piher sensors are compact, low-profile, yet extremely rugged and can be custom-engineered to fit existing mechanical assemblies.
