TMR4003
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 posed 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) operation
- Excellent thermal stability
- pact package
