TMR4004 - TMR Geartooth Sensor

Download the TMR4004 datasheet PDF. This datasheet also covers the TMR4001 variant, as both devices belong to the same tmr geartooth sensor family and are provided as variant models within a single manufacturer datasheet.

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.
