RedRock TMR Low-Power Magnetic Switch Sensor

RedRock TMR Low-Power Magnetic Switch Sensor


Coto Technology’s RedRock TMR ultra-low-power magnetic switch sensor features high sensitivity and miniature size

Coto Technology’s RedRock series of analog and digital TMR low-power magnetic switch sensors are ideally suited to the demands of next-generation security, metering, medical, automotive, instrumentation, industrial markets, and any application requiring a magnet and sensor. Due to their ultra-low-power (especially important in battery-powered applications), high sensitivity, miniature size, robustness, and availability, TMR sensors are a popular alternative to both Hall effect sensors and reed switches. Target applications include fluid level detection; door, window or lid open-close detection; water and gas meters; proximity sensing; rotary sensing; and any application where the device or product needs to wake up, turn on, and perform, thus providing a true out-of-the-box experience. These tiny sensors offer high magnetic sensitivity with high hysteresis, EMF resistance, and a small package size, all while consuming extremely low power.



  • Low power consumption
  • High sensitivity
  • Stable temperature performance
  • Resistant to mechanical stress
  • Tiny size
  • Reach compliant
  • RoHS compliant
