Version 2.0.2 TMR4M02B/3B/4B/5B/8B TMR Geartooth Sensor Description The TMR4M02B/3B/4B/5B/8B geartooth sensors are posed 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 pact 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 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 - - Ro HS and REACH pliant Applications - - Gear speed and direction measurement - - Linear and angular speed sensing - - Linear and angular displacement sensing LGA6L Multi Dimension Technology Co., Ltd. http://.dowaytech./en/ Output Voltage (V) Phase A output V1+ - V1Phase B output V2+ -...
