One magnet, One electronics module. No gears. Nothing to wear out over a lifetime. A sensor that will deliver the same level of precision and stability throughout its life as the first day it was installed -despite extremes of vibration, shock, temperature and contamination. Something that is easy to assemble -delivering additional cost reduction on the production line. Something that can be fitted anywhere on the pivoting shaft, giving engineers the flexibility to be creative. Main features. Our touchless sensor is Piher Sensing Systems at its best, packaging its True touchless operation: free from wear and tear. core technology -slimline magnetic Hall Effect sensing- into something Low profile & robust magnetic design that easily adapts to your truly original. design. Selectable output: analogue (ratiometric) or PWM. SPI upon request. Programmable measuring range: up to 12mm. Resolution: analogue & PWM: 12 bits / SPI: 14 bits. Linearity: +/-1% absolute (+/-0.5% upon request). Over voltage protection up to 30V. Reverse voltage protection up to -50V. Supply voltage up to 30V. Programmable linear transfer characteristic (some positive slopes & one negative slope can be programmed in the Lateral magnet linear displacement Concentric magnet linear displacement version. version. same transfer characteristic up to 4 programmable points) Unlimited mechanical life. High vertical & lateral tolerance to magnet misalignment. Simple, redundant and full redundant versions available. Sealed for harsh environments. Operating temperature: -40C to +125C Touchless Self-diagnostic features. working principle Measurement of linear position Agriculture. using variation of magnetic field amplitude induced by the Construction & forestry. displacement of a moving Material handling. magnet has been intensively Lifts & cranes. developed over the last fifteen Marine. years.

The linear touchless linear sensors create immunity to magnets The technology used by Piher is only sensitive to the flux density misalignment that negatively impacts operational performance and coplanar with the IC surface. results in labour intensive maintenance programmes. It complements our concentric and variable air-gap touchless series of non-contact angular rotary position sensors. The absolute position information is computed from both vectorial components of the flux density (i.e. BX and BY) of a magnet. Then The magnet is attached to the moving parts whose displacement is an output signal proportional to the decoded position is produced. to be measured, such as hydraulic/pneumatic controls or gear selector, and the electronics module is fixed to the chassis (or vice versa). As absolute sensors, they will not lose the values even after a power failure. All Piher touchless sensors are compact, sealed, low-profile, yet extremely rugged and can be custom-engineered to fit customers specifications and existing mechanical assemblies.
