Applications


The RedRock™ RR122-3CU2/3CU3 sensor series from Coto Technology is a range of digital push-pull magnetic sensors with turbo mode designed using a patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. The RR122-3CU2/3CU3 series features a typical operate sensitivity of 10 G (1 mT), with a bipolar latching 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 0.8μA at 3V/100Hz (typical), 75μA at 3V/10kHz (typical), and are available with operating temperature ranges of -40°C to +85°C (RR122-3CU2-511) or -40°C to +125°C (RR122-3CU3-511). These sensors are ideal for use in medical, industrial, automotive, and consumer applications.
