RR142-1LD2-545

RR142-1LD2-545 is a RR142 series REDROCK® TMR digital + analog multichannel sensor. It is a multi-channel magnetic sensor with multiple output options ideal for use in medical, industrial, automotive, and consumer applications. Based on patented Tunneling Magnetoresistance (TMR) technology with seamless CMOS integration, it offers multiple configurations of several parameters to enable applications like proximity sensing, rotary sensing, and level detection. It features both digital and analog channels. It offers an innovative new option to meet the needs of next-generation applications. For “wake-up” applications, the analog output functionally is kept inactive until the sensor detects the removal of a nearby magnetic field (B <lt/> Brp). The application includes proximity detection, rotary sensing, fluid level detection, door and lid closure detection, utility meters, portable medical devices, motor controllers, consumer electronics, and wake-up µProcessor.
