The RedRock® RR122-1A52-511 and RR122-1A53-511 are digital TMR 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 RR122-1A52-511 and RR122-1A53-511 feature an operate sensitivity of 9 G (0.9 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 extremely low average current drain (1.0µA) for an active magnetic sensor operating at 250 Hz and high operating temperature range from -40°C up to +125°C. (See Datasheet)
