RedRock® RR132-1B12-551/552 & RR132-1B13-551/552 TMR Digital Open-Drain Magnetic Sensor

The RedRock® RR132-1B12-551/552 and RR132-1B13-551/552 are digital magnetic sensors ideal for use in medical, industrial, automotive, and consumer applications. It is based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration.  Short lead times are making RedRock® TMR Magnetic Sensors a popular replacement alternative for hard-to-get Hall Effect Sensors and Reed Switches.

The RR132-1B12-551/552 and RR132-1B13-551/552 feature an operate sensitivity of 30 G (3 mT), with an omnipolar 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 (50nA) – the world’s lowest for an active magnetic sensor, operating at 2 Hz and high operating temperature range from -40°C up to +125°C.  (See Datasheet)
