RR122-2B22-511 & RR122-2B23-511 TMR Digital Push-Pull Magnetic Sensor

RR122-2B22-511 & RR122-2B23-511 TMR Digital Push-Pull Magnetic Sensor

The RedRock™ RR122-2B22-511 and RR122-2B23-511 are digital magnetic sensor ideal for use in medical, industrial, automotive, and consumer applications. They are based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. Short lead times are making RedRock® RR122 TMR Magnetic Sensors a popular replacement alternative for hard-to-get Hall Effect Sensors and Reed Switches.

The RR122-2B22-511 and RR122-2B23-5112 feature an operate sensitivity of 30 G (3 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 (100nA) for an active magnetic sensor operating at 10 Hz and high operating temperature range from -40°C up to +125°C.
