RJM3143 · TMR 3D Position / Angle Sensor
TMR tunnel-magnetoresistance analog output with highly sensitive 3D magnetic field detection for angle and position measurement. Pin-to-pin compatible with TDK TAS2143.
RJM3143 is built on TMR (tunnel magnetoresistance) technology for highly sensitive 3D magnetic field detection with analog output, targeting high-accuracy angle and position measurements such as steering angle and actuator position.
It is pin-compatible with the TDK TAS2143 and comes in a TSSOP8 package, making it straightforward to localize the supply of an existing design.
