Variable Air Gap Arc Position Sensor.

Piher Sensing Systems’ PS2P-ARC touchless variable air gap position sensor creates immunity to radial and axial play on pivot joints where misalignment result in poor operational performance and labor intensive maintenance programs. The magnet is attached to the rotating parts of a pivot joint and the electronics module to the chassis (or vice versa). Without the need for any gears or linkages the sensor is easy to mount thereby delivering additional cost reduction on the production line and improving product reliability and durability during its lifetime.

Different magnet configurations arc position sensor

The PS2P-ARC measures changes in position relative to the sensor by detecting the movement of a sinusoidal magnetized arc magnet that is located in a separate housing and is only sensitive to the flux density co-planar with the IC surface. The PS2P series is complemented by touchless linear (PS2P-LIN) and angular (PS2P-CON) position sensors. All sensors of the series will deliver the same level of precision and stability throughout their lifetime as on the first day they are installed - despite extremes of vibration, shock, temperature and contamination and as absolute sensors they will not loose the values even after a power failure.

KEY FEATURES
icon play resistant sensor Immune to radial and axial play
Maintains stable electrical output and specified linearity despite radial and axial tolerances avoiding performance loss and maintenance cost.
icon touchless sensor True touchless operation
Without any internal or external gears or linkages the sensor is easily assembled and calibrated and free from wear and tear over lifetime.
icon compact Compact and low profile package
Without the need for a shaft or lever the sensor is provided in a exceptionally compact and low profile package that fits in space constraint applications.
harsh sensor Made for harsh environments
The rugged package protects the sensor from dust, moisture, vibration and extreme temperatures for usage in the most demanding environments.
icon virtually unlimited life Unlimited mechanical life
The separation of electronics and magnet module allows for a virtually unlimited lifetime independent of number of revolutions.
icon custom sensor Adaptable to your requirements
Custom mechanical design, programmable transfer function and switch outputs as well as different output protocols and redundancy levels available.
