Murata MRMS AMR Sensors

Murata MRMS Anisotropic Magneto Resistance (AMR) Sensors are magnetic sensors designed with AMR components whose resistance fluctuates depending on the strength or direction of the magnetic field. The MRMS magnetic sensors detect a horizontal magnetic field, allowing a single magnet to support multiple sensing positions. These sensors offer a wider detection area and more design flexibility in terms of mounting location compared to hall ICs. Murata MRMS sensors feature a supply voltage range from 1.6V to 5.5V. Typically, MRMS magnetic sensors are used in aircraft equipment, digital cameras, medical equipment, refrigerators, and washing machines.
