xMR Sensor ICs for applications in Automotive, Industrial, Automation, IoT, Consumer devices and beyond.
Discover our range of magnetoresistive sensor ICs
based on proprietary AMR, GMR and TMR technology,
researched and developed indigenously in India.
AMR
Anisotropic magnetoresistance (AMR) refers to the change in electrical resistance of a ferromagnetic material when its magnetization is rotated relative to the current direction.
GMR
Giant magnetoresistance (GMR) refers to the quantum mechanical phenomena that causes a significant change in electrical resistance when the magnetization of neighboring ferromagnetic layers switches between parallel and antiparallel.
TMR
Tunneling magnetoresistance (TMR) is the effect of spin-dependent electron tunneling through the nanometer layer of dielectric or semiconductor, located between two ferromagnets.

High sensitivity
The MR sensors are up to 50 times more sensitive than with all other known magnetic solid-state effects, such as the Hall effect. MR sensors can detect the Earth's magnetic field for compass applications and are used successfully for non-destructive material testing and vehicle recognition. In these applications, extremely weak magnetic fields are measured very accurately.
High accuracy
MR sensors feature inherently low hysteresis and high linearity. Sensohm designs for angle and length measurement, as well as compensation techniques for current measurement provide even better performance for particularly demanding measurement applications.
High resolution
MR sensors boast a very high resolution, which is particularly important in applications requiring very good control quality, such as encoders for direct drives. The low noise level associated with MR sensors combined with the large signal amplitude results in an excellent signal-to-noise ratio.
Dynamics
MR sensors have an extremely high bandwidth and can detect magnetic fields with frequencies in the megahertz range. They are therefore well suited to high-speed applications, for example, high-frequency machine tool spindles.
High reliability
The solid-state and non-contacting measurement principle means that MR sensors are intrinsically safe. This is backed by the extensive and intensive qualification tests according to the latest industrial and automotive standards with results that confirm the long-term stability and reliability of Sensohm MR sensors.
Durability
MR sensors are fundamentally insensitive to very high or very low temperatures, oil, dirt or mechanical loads from shocks or vibrations. They can also be used in radiation and in a vacuum. Regardless of whether at -120°C 400 million kilometers away on Mars or 10 kilometers deep in the Earth at +200°C in an oil well, Sensohm MR sensors are always reliable and durable under the harshest conditions.
Energy efficiency
MR sensors can be specially designed with a high internal resistance, making them well suited to battery powered applications. Thanks to the integrated compensation conductor, current sensors require a very low compensation current, making Sensohm current sensors extremely energy efficient.
Galvanic isolation
The non-contacting measurement principle of MR sensors is ideal for applications that demand safe electrical isolation.
Easy to integrate
Sensohm MR sensors are inherently compact and their high sensitivity allows them to bridge mechanically dependent distances and tolerances to the measurement scale. This makes them particularly easy to integrate in designs in which there is not much installation space, tolerances are unavoidable and assembly costs should be kept to a minimum.
