The RedRock™ RR112-1G42/1G43 sensor series from Coto Technology is a range of analog magnetic sensors designed using a patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. The RR112-1G42/1G43 series features a typical operate sensitivity from -80 G to +80 G (typical), with a linear analog voltage 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 1.5μA (at 3V and operating at 100Hz) and are available with operating temperature ranges of -40°C to +85°C (RR112-1G42-531/RR112-1G42-532) or -40°C to +125°C (RR112-1G43-531/RR112-1G43-532). These sensors are ideal for use in medical, industrial, automotive, and consumer applications.
