MR-Sensors
Where do you use MR-sensors?
MR-sensors, evaluation electronics and magnetic scales from Sensitec are in use everywhere, where movement is being controlled and steered, where paths, angles, positions, electric or magnetic fields are measured and detected.
What is the MR effect?
The MagnetoResistive Effect, "MR-Effect", has been known for 150 years. However, its use in sensor applications was first made practically possible through the development of thin-film technology some 30 years ago.

Our exhibition team is looking forward to presenting you our new products and innovations and to giving you technical advice for your individual measuring application.
Measurement Technology
Hand-held measuring devices increasingly feature electronic position feedback systems. This provides the data for digital readouts or for integrated control systems that give additional functionality to previously mechanical devices. The robustness of MR-sensors is a key argument in this type of application, where the measurement system must withstand the demands of the workshop environment.
Typical Applications
- Linear encoder for workshop slide gauge
- Linear encoder for electro-mechanical calliper
- Measurement system for portable hardness tester
APPLICATION EXAMPLE: Stroke measurement in a workshop calliper gauge
Requirements
Stroke measurement in a workshop calliper gauge that should be non-contacting and resistant to humidity.
Key Specifications
