RedRock® RR122-1B92-511/512 & RR122-1B93-511/512 TMR Digital Push-Pull Magnetic Sensor

The RedRock® RR122-1B92-511/512 and RR122-1B93-511/512 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 RR122-1B92-511/512 and RR122-1B93-511/512 feature an operate sensitivity of 30 G (3.0 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 ultra low power consumption (32 mA) for an active magnetic sensor operating at 10 kHz and high operating temperature range from -40°C up to +125°C.
