d e v r e s s t e k r a m * * * * * * PS2P-CON. Rotary concentric touchless sensor Description. Something that is truly contactless. 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 core True touchless operation: free from wear and tear. technology -slimline magnetic Hall Effect sensing- into something truly original. Low profile & robust magnetic design that easily adapts to your design. Selectable output: analogue (ratiometric) or PWM. SPI upon request. Programmable angular range up to 360 degrees. Nominal air gap: 3mm between plastic parts. Maximum air gap: 5mm. For higher air gap: check availability. Maximum magnet radial offset allowed: 3mm. (Measured directly on non-ferromagnetic material. For other configurations check with Piher.) Resolution: analogue & PWM: 12 bits / SPI: 14 bits. Big vertical & lateral magnet misalignment allowed. Linearity: +/-1% absolute (+/-0.5% upon request). Over voltage protection. Reverse voltage protection. Supply voltage up to 25V. Programmable Linear Transfer Characteristic. Touchless (Some positive slopes & one negative slope can be programmed in the same working principle transfer characteristic up to 4 programmable points) Measurement of angular Unlimited mechanical life. position using variation of High vertical & lateral tolerance to magnet misalignment. magnetic field amplitude induced by the displacement of Simple, redundant and full redundant versions available. a moving magnet has been intensively developed over the Sealed for harsh environments. last fifteen years. However, Operating temperature: -40C to +125C. these solutions have limits in terms of angular range and Self-diagnostic features. temperature influence. The technology used by Piher is Sensing the position, avoiding contact. only sensitive to the flux density coplanar with the IC surface. The angular information is computed from both vectorial The concentric touchless linear sensors create immunity to magnets components of the flux density (i.e. BX and BY) of a magnet. Then misalignment that negatively impacts operational performance and an output signal proportional to the decoded angle is produced. results in labour intensive maintenance programmes. It complements our linear and variable air-gap touchless series of non-contact angular rotary position sensors. The magnet is attached to the moving parts whose displacement is Agriculture.

Material handling. Medical. 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.
