RR121
RR121 is TMR DIGITAL PUSH-PULL MAGNETIC SENSOR manufactured by COTO.
Description
The Red Rock™ RR121 Series is a magnetic sensor with digital pushpull output ideal for use in medical, industrial, automotive, and consumer applications. Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, the RR121 offers multiple configurations of several parameters to enable applications like proximity sensing, rotary sensing, and level detection.
The RR121 features available operate sensitivities from 9 G (0.9 m T) to 70 G (7 m T), and either omnipolar, unipolar, or bipolar magnetic field response. It has the world’s lowest average current drain (200 n A) for an active magnetic sensor, as well as operating frequencies up to 10 k Hz and high operating temperature ranges from -40°C up to 125°C.
