TMR Magnetic Sensors & Switches

Using proven ultra low power consumption TMR magnetic sensor technology, the high-performance RedRock® analog and digital TMR magnetic sensors have numerous technologically-advanced applications in multiple markets.

Offering the lowest power consumption, highest sensitivity, ultra-miniature package size, short lead times and a highly-competitive price, the TMR Magnetic Sensor devices are ideally suited to the demands of next generation security, metering, medical, automotive, instrumentation, and industrial markets. Target applications include fluid level detection, open-close / proximity detection, rotary sensing, tablets and laptops, “wake-up” and more. Due to their low power consumption, high sensitivity, small size and ready availability, RedRock® magnetic sensors are popular alternatives to existing Hall Effect sensors and Reed Switches.
