RedRock® RR131 Series TMR Digital Magnetic Switch

The RedRock® RR131 Series is a magnetic switch with digital open drain output ideal for use in medical, industrial, automotive, and consumer applications. Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, the RR131 is capable of multiple configurations of several parameters to enable applications like proximity sensing, limit switching, and level detection.
The RR131 features multiple operate sensitivities in both omnipolar and unipolar magnetic field responses.  It has the world’s lowest average current drain (200 nA) for an active magnetic switch, as well as high operating temperature ranges from -40°C up to 125°C.

Please note:  This Product Series is approaching end of life and is not recommended for new designs.
For new designs, please consult the end of life announcement which specifies recommended new RedRock series replacements.
