Touchless Variable Gap Sensor is immune to radial and axial play.

Press Release Summary:

Achieving play-resistant performance on mobile shafts due to circular arc magnet, custom 2-piece magnetic Hall effect variable gap sensor can be custom-engineered to fit existing mechanical assemblies for mission-critical off-road, construction, and marine applications. Stable electrical output and specified linearity is maintained between both sensor packages for over 50 million cycles despite radial and axial play such as ±1.5 to ±7 mm (and upwards), respectively.

PIHER Introduces Touchless Variable Gap Sensor

Brighton, MI – PIHER Sensors and Controls S.A. introduces a new custom sensor suitable for the harshest of environments, a two-piece magnetic Hall effect variable gap sensor that maintains stable electrical output and specified linearity on mobile shafts, despite radial and axial movement.

The new variable gap sensor is immune to typical radial and axial play on mobile shafts where significant misalignment often results in poor operational performance and labor-intensive maintenance. The play resistance performance is achieved by means of a circular arc magnet (where 360º rotation angle is unnecessary) that is attached to rotating shafts or assemblies, such as boom loaders, skid steers, buckets and hitch arms, and the electronics module to the chassis (or vice versa).

“This sensor’s ability to maintain reliable and stable positioning, no matter the environment, will be invaluable in mission critical applications such as off-road, construction and marine applications,” says Jose Luis Macía, Program Manager.

Over 50 million cycles, stable electrical output and the specified linearity is maintained between both sensor packages, despite any radial and axial play such as +/-1.5 to +/-7mm (and upwards) respectively.

All Piher sensors are low-profile, yet extremely rugged and can be custom-engineered to fit existing mechanical assemblies for a wide range of industrial, off-road and marine applications.
