Coto Technology RedRock® RR132 TMR Magnetic Switch Sensors

Coto Technology RedRock® RR132 TMR Magnetic Switch Sensors are digital TMR low power magnetic switch sensors ideally suited to the demands of next generation security, metering, medical, automotive, instrumentation, industrial markets, and any application requiring a magnet and sensor. TMR sensors are a popular alternative to Hall Effect sensors and Reed switches due to their ultra-low power (especially important in battery-powered applications), high sensitivity, miniature size, robustness, and availability.

Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, the RedRock RR132 series incorporates digital magnetic sensors ideal for use in medical, industrial, automotive, and consumer applications. The RR132 series features operating sensitivities ranging from 15G to 30G, with omnipolar or unipolar magnetic field responses. The series offers a wide supply voltage range from 1.7V up to 5.5V, ideal for applications ranging from small battery-powered electronics to industrial machinery. They over a very low average current drain for an active magnetic sensor, with a wide range of operating frequencies ranging from 2Hz up to 20Hz and a high operating temperature range from -40°C up to +125°C.

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. These tiny sensors offer high magnetic sensitivity with high hysteresis, EMF resistance, and small package size, all while consuming extremely low power.
