RedRock® RR132-2E22-551 & RR132-2E23-551 TMR Digital Open-Drain Magnetic Sensor

The RedRock® RR132-2E22-551 and RR132-2E23-551 are digital magnetic sensors ideal for use in medical, industrial, automotive, and consumer applications. They are based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration.

The RR132-2E22-551 and RR132-2E23-551 feature an operate sensitivity of 15 G (1.5 mT), with a unipolar magnetic field response. They offer a wide supply voltage range from 1.7 up to 5.5 V, ideal for applications ranging from small battery-powered electronics to industrial machinery. They have an ultra low power consumption (70nA) – the world’s lowest for an active magnetic sensor operating at 10 Hz and high operating temperature range from -40°C up to +125°C.
