| TMR Technologies Brief |
| TMR (Tunnel Magneto Resistance) is a new technology, using magneto resistance effect sensors for industrial applications in recent years. It's tunnel magneto resistance effect is induced by magnetic multilayer film material, the rate of resistance change of TMR performs better than AMR's and GMR's. We usually refer TMR to Magnetic Tunnel Junction (MTJ). Comparing with the Hall element, the MTJ element has better thermal stability, higher sensitivity, lower power consumption, better linearity, no additional polyethylene magnetic circular structure. Relative to AMR, TMR has better temperature stability, higher sensitivity, wider linear range and no additional set / reset coil structure; Relative to the GMR, TMR has higher stability in temperature, higher sensitivity, lower power consumption and wider linear range. Our target customers are the top supplier of automotive components and systems |
| TMR Angle Sensors |  | ||
| There is a growing demand for high-accuracy angle detection in the fields of vehicle electrical components, industrial equipment, and consumer electronics. TDK has applied TMR technology, which has shown excellent performance in HDD heads, to develop sensors that have high-output, resistant to noise and have high angle accuracy. TDK offers angle sensors with high stability in temperature and compact package that are fit into automobiles. They have already been under mass production, and used in a wide range of applications which require high accuracy and stability, namely EPS motors. | |||
