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. 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. The high-sensitivity performance of the TMR40xx series enables detection of small magnetic field changes, and its output signal has good temperature stability.

The TMR40xx series is available in two compact LGA6L(3 mm × 3 mm × 0.9 mm) and LGA6L(3 mm × 6 mm × 0.9 mm) packages, with multiple configuration of TMR sensing element spacing:

• TMR4001:0.25 mm   • TMR4002:0.5 mm

• TMR4003:0.75 mm   • TMR4004:0.5 mm
