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. The period of this signal equals to the gear

pitch to measure the rotation position and direction of

the gear.

The TMR4M02B/3B/4B/5B/8B series are available

in the compact LGA6L (3 mm × 6 mm × 0.9 mm)

packages, with different configurations of gear pitches

in following gear modules:

? TMR4M02B: module 0.2

? TMR4M03B: module 0.3

? TMR4M04B: module 0.4

? TMR4M05B: module 0.5

? TMR4M08B: module 0.8
