The RedRock™ RR111 Series is a magnetic sensor with a continuous analog output linearly proportional to an applied magnetic field. Ideal for use in medical, industrial, automotive, and consumer applications, they are based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration. The RR111 enables applications like proximity sensing, and continuous level detection. The RR111 features a low average current drain (1.6 mA) for a continuously active magnetic sensor and temperature range from -40°C up to 85°C. It comes in an SOT-23-3 package measuring 2.9 x 1.6 x 1.2 mm as well as an LGA-4 package measuring just 1.4 x 1.4 x 0.45 mm.
