New Generation COTO RED ROCK

TMR (Tunneling MagnetoResistance) is the next-generation sensing technology for applications like storage/automotive/metering/motor control ..and etc

  • TMR sensor measures magnetic flux from rotary wheel to estimate flow speed/direction
  • High sensitivity TMR sensor could extend air gap and minimize magnet size & diversity
  • Low power consumption TMR sensor is a battery-wise solution for metering application.
  • TMR sensors allow higher resolution compared to bare-glass reed switches.
  • Robust packaging compared to bare glass reed switches. No cracking or contamination due to semiconductor process and packaging
