TMR4MxxB Series TMR Geartooth Sensor
●The TMR4MxxB 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 TMR40MxxB series is available in two compact LGA6L packages, with different configurations of gear pitches in following gear modules:
◆TMR4M02B: module 0.2
◆TMR4M04B: module 0.4
◆TMR4M05B: module 0.5
◆TMR4M08B: module 0.8.
■FEATURES AND BENEFITS:
●Tunneling magnetoresistance (TMR) technology
●Adapt to gears of different modules
●High saturation field
●DC (zero speed) operation
●Sine/cosine signal output with accurate phase difference
●Excellent thermal stability
●Excellent resistance to external magnetic field interference
●RoHS and REACH Compliant
