Analog Devices Inc. ADMAGB3476 Magnet & ADMAGMECH04 Magnetic Shield
Analog Devices ADMAGB3476 Magnet and ADMAGMECH04 Stray Magnetic Field Shield provide a robust solution for maintaining the magnetic window requirements of the ADMT4000 sensor. The integrated shielding provides protection against stray magnetic fields, which is crucial for accurate measurements. The integrated magnet shield rotates with the magnet, resulting in low angular hysteresis. Manufactured from samarium cobalt (SmCo), the magnet maintains the magnetic operating window of the Analog Devices ADMT4000 over the entire temperature range.
