General Description

The TMR4M02B/3B/4B/5B/8B geartooth sensors are composed of a dual-channel push-pull Wheatstone full bridge including eight high-sensitivity tunneling magnetoresistance (TMR) sensing elements.

The placement of TMR sensing elements is designed for specific gear pitches in different gear modules.

The dual-channel Wheatstone full bridge outputs two orthogonal sine and cosine signals with the rotation of the gears.
