MDT Introduces AMR4020VD, a High-Precision Magnetic Scale Sensor IC

MultiDimension Technology (MDT), a supplier of magnetic sensors known for its work in Tunneling Magnetoresistance (TMR) technology, has announced the launch of its AMR4020VD, a high-precision magnetic scale sensor IC designed for linear and rotary displacement measurement. MDT will display the new sensor alongside its broader TMR and AMR magnetic sensor lineup at Electronica Shanghai 2026 (Booth N3.501).

The AMR4020VD pairs MDT's advanced AMR sensor design with an innovative package design to deliver high measurement accuracy, strong temperature stability, solid resistance to external magnetic field interference, and simpler integration for compact encoder designs. The sensor eases many of the alignment and mounting constraints typical of conventional magnetic scale sensors, giving engineers more design flexibility for next-generation encoder and motion control systems.

A notable feature of the AMR4020VD is its ability to support both perpendicular and parallel PCB mounting relative to the magnetic scale or magnetic ring. While conventional solutions typically require mounting the sensor along the PCB edge, the AMR4020VD allows for parallel mounting instead, making better ...
