The MRA 1427/1426 magnetic sensor utilizes Giant magneto-resistive (GMR) technology, where highly sensitive unshielded GMR elements are configured in a form of single Wheatstone bridge. The Wheatstone bridge generates a differential output voltage with respect to magnetic field gradient along the sensor's sensitive direction. Each resistor has 45 kΩ nominal resistance and output of the bridge is purely ratiometric with the power supply voltage. Due to our unique technology and design, MRA 1427 is highly sensitive and has the ability to detect signals at the wide air gap. The excellent thermal and voltage stability makes it suitable for challenging environments.
The MRA 1427 GMR sensor available in 8T-DFN package with dimensions 3 mm x 3 mm x 0.75 mm.
