Compact Panel Mount Hall-Effect Rotary Sensor with Mechanical Stop

Piher Sensing Systems’ PSE Series Rotary Position Sensors are based on contactless Hall-effect technology and deliver high accuracy and linearity in a compact package. Increased rotational life and robustness against humidity, vibration and shock make them perfectly suited for harsh industrial and transportation environments. These absolute sensors will not lose its values even after a power failure.

By integrating a mechanical stop at 290 degrees unintentional over travel is mechanically prevented. This makes the PSE-290 especially suitable for human machine input. Custom versions with different shafts, mechanical  or electrical rotational angle can be delivered on request.


Without any gears or mechanical interfaces the sensor is easily assembled and calibrated and subject to limited wear and tear over lifetime.
Reliably stops the rotary movement at a maximum rotational travel of 290 degrees.
The magnet is securely fastened to the shaft and acts as only moving component in the sensor.
The rugged package protects the sensor from dust, moisture, vibration and extreme temperatures for usage in the most demanding environments.

Custom mechanical design, programmable transfer function as well as different output protocols and redundancy levels available.
