Features, Applications

The RedRockTM RR121 Series is a digital logic sensor 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 G (0.9 mT) G (10 mT), and either omnipolar, unipolar, or bipolar magnetic field response. It has the world's lowest average current drain (190 nA) for an active magnetic sensor, as well as operating frequencies to 333 kHz and high operating temperature ranges from to 125C.

Notes: m 1. Unless otherwise specifice, all characteristics as measured 25C 2. See "Magnetic Field vs. Output Status" (at right) for more details.

The output voltage on the RR121 is active low, meaning that while a sufficiently strong magnetic field is present, the output voltage is low. The output voltage can be connected to a digital I/O pin on a microcontroller. A decoupling capacitor between the supply voltage and ground is required with placement close to the magnetic sensor. A typical capacitor value 1.0 mF will suffice.

Note: 1. Custom options available for Sensitivity, Frequency, Temperature Rating, Supply Voltage, Output Response & more. Please contact redrock@cotorelay.com for more details.
