Product Details

The ADMAGB3476 and ADMAGMECH04 provide a robust solution for maintaining magnetic window requirements of the ADMT4000. The integrated shielding provides protection against stray magnetic fields, which is crucial for accurate measurements. The integrated magnet shield rotates with the magnet to result in low angular hysteresis. Manufactured from samarium cobalt (SmCo), the magnet maintains the magnetic operating window of the ADMT4000 over the entire temperature range.
