The RedRock™ RR122-1A52/1A53 sensor series from Coto Technology is a range of digital push-pull magnetic sensors designed using a patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. The RR122-1A52/1A53 series features a typical operate sensitivity of 9 G (0.9mT), with an omnipolar magnetic field response. They offer a wide supply voltage range from 1.7V to 5.5V, ideal for applications ranging from small battery-powered electronics to industrial machinery. The TMR sensors have a typical current drain of 1.3μA (at 3V and operating at 10Hz), and are available with operating temperature ranges of -40°C to +85°C (RR122-1A52-511) or -40°C to +125°C (RR122-1A53-511). These sensors are ideal for use in medical, industrial, automotive, and consumer applications.
