Inductive Angular Arc Position Sensor

Piher Sensing Systems’ Inductive Arc Position Sensors are conceived for heavy-duty applications such as tractors, excavators and loaders. Inductive sensors do not depend on magnets, but detect the position of a solid metallic target that can easily be integrated into the existing machinery structure.
In addition to the sensors’ excellent accuracy, IP67 and IP69K sealing and high temperature tolerance make these absolute position sensors an excellent choice for harsh environments typically found in off-highway applications.
The arc design enables a simple and fast assembly and calibration process at the manufacturing line, leading to additional cost savings during the production process.

KEY FEATURES

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.

Immune to magnetic stray fields

No shielding required as inductive technology is not affected by electromagnetic stray fields.

Unlimited mechanical life

The separation of electronics and magnet module allows for a virtually unlimited lifetime independent of number of revolutions.

Compact and low profile package

The sensor target can be integrated into the existing application, and the sensor itself comes in an exceptionally compact and low profile package.

Made for harsh environments

The rugged package protects the sensor from dust, moisture, vibration and extreme temperatures for usage in the most demanding environments.

Adaptable to your requirements

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