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.
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).
