Coto Technology RedRock® RR112 TMR Analog Magnetic Switch Sensors
Coto Technology RedRock® RR112 TMR Analog Magnetic Switch Sensors are ideally suited to the demands of next-generation security, metering, medical, automotive, instrumentation, and industrial markets. These TMR sensors are a prevalent alternative to Hall-effect sensors and reed switches due to their ultra-low power, high sensitivity, miniature size, robustness, and availability. The RR112 sensors offer multiple configurations of several parameters to enable applications such as proximity sensing, rotary sensing, and level detection. These magnetic switch sensors encompass the RR112-1D9x and the RR112-1G4x, offering flexibility around magnetic sensitivity, magnetic range, sensing frequency, and power consumption.
The RR112 sensors operate with a wide supply voltage range of 1.7V up to 5.5V. Target applications include fluid-level detection, door, window, or lid open-close detection, water and gas meters, portable medical devices, consumer electronics, and IoT devices.
