PIHER - Inductive Linear Position Sensor
Piher Sensing Systems develops custom Inductive Linear Position Sensors for applications such as transmissions, suspensions and steering systems in automotive, two-wheelers and off-highway vehicles. We provide custom product design and adaptations to meet any form, fit and function, including the choice of digital or analog output, wire harness and interface connector.
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, up to 14bit resolution, IP67 and IP69K sealing, stray-field immunity and high temperature tolerance make these absolute position sensors an excellent choice for harsh environments typically found in automotive and off-highway applications.
Thanks to the extended measuring range, sensitivity to any metal material, high tolerance to misalignment between the sensor and the target, and low cost, Piher’s inductive sensors are the ideal alternative to LVDTs.
Immune to magnetic stray fields
No shielding required as inductive technology is not affected by electromagnetic stray fields.
Made for harsh environments
The rugged package protects the sensor from dust, moisture, vibration and extreme temperatures for usage in the most demanding environments.
Low weight and compact dimensions
Reduced size and weight compared to resolvers.
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.
Unlimited mechanical life
The separation of electronics and magnet module allows for a virtually unlimited lifetime independent of number of revolutions.
Long measurement ranges
Precise, touchless linear position measurement for stroke length from 10 mm to 800 mm.
Quick and simple replacement
If needed, the sensor inside the housing can be swapped out quickly and easily on site (in the field), saving both time and downtime expenses.
