Approximate Maximum Working Gap: 12" 13,000 gauss per 2/cm @ 250mm (5/8") 7,000 gauss per 2/cm @ 350mm (8") Approximate Belt Speed: 4.26ft/s Lifting Eyes & Stainless Steel Framework High powered non-deteriorating compact permanent magnet design. Alternating poles contain the magnetic field into the working area and minimize stray magnetic flux. This is a deep field high intensity magnetic system, with a similar performance to many rare earth magnet systems at the working gap.
