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. 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 RR122-1B92-511/512 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 μA) for an active magnetic sensor operating at 10 kHz and high operating temperature range from -40°C up to +125°C.  (See Complete Datasheet)
