MultiDimension Technology (MDT), a developer of magnetic sensors specializing in tunneling magnetoresistance (TMR) technology, unveils its AMR4020VD magnetic scale sensor IC for linear and rotary displacement measurement. According to MDT, the chip pairs the company’s AMR sensor design with an innovative package design that significantly relaxes the alignment and mounting constraints of conventional magnetic scale sensors, thereby enabling greater design flexibility for next-gen encoder and motion control systems.
The AMR4020VD supports both perpendicular and parallel PCB mounting relative to the magnetic scale or magnetic ring. Conventional components require mounting the sensor along the PCB edge. The AMR4020VD enables parallel PCB mounting, maximizing board space while simplifying routing and system integration.
Reportedly, the design also enables more consistent air-gap control during assembly, improving assembly consistency and manufacturing yield while maintaining high positioning accuracy. Target applications include industrial encoders, CNC machines, linear motors, robotics, semiconductor manufacturing equipment, precision positioning stages, and other motion control applications.
The AMR4020VD is available through MDT’s online store. For deeper details, procure and peruse the AMR4020VD datasheet,
