TMR4001 - TMR Geartooth Sensor

General Description

The TMR40xx series of geartooth sensor adopts a unique push-pull Wheatstone bridge design.

This design includes a single-channel or dual-channel Wheatstone full bridge composed of four or eight unshielded high-sensitivity tunneling magnetoresistance (TMR) sensing elements.

Key Features

  • Tunneling magnetoresistance (TMR) technology.
  • High saturation field allows operation in large DC magnetic field.
  • High sensitivity to magnetic gradient.
  • Compatible to small pitch gear measurement.
  • Sine/cosine signal output with accurate phase difference.
  • Excellent resistance to external magnetic field interference.
  • Wide air gap tolerance.
  • DC (zero speed).

Datasheet Version 2.0.1 TMR40xx TMR Geartooth Sensor Description The TMR40xx series of geartooth sensor adopts a unique push-pull Wheatstone bridge design. This design includes a single-channel or dual-channel Wheatstone full bridge composed of four or eight unshielded high-sensitivity tunneling magnetoresistance (TMR) sensing elements. The Wheatstone bridge provides a differential voltage output along the gradient of the applied magnetic field along the sensor’s sensing direction. The dual-channel Wheatstone full bridge generates two orthogonal sine/cosine voltage output signals to measure the position of the gear rotation and detect the direction of rotation.
