² Holding force
The holding forces are ascertained using an even polished plate of ST 37 material with a thickness of 10 mm by the vertical withdrawal of the magnet at room temperature. Small cracks in the magnet material do not affect the holding force. Deviations up to minus 10 % are possible in some instances. The data given relates to minimum values which are normally exceeded.
Material designation
REFeB is the official designation for NdFeB materials according to DIN IEC 60404-8-1, February edition 2003 (replaces DIN 17410).
Description
This series consists of permanent-magnetic holding systems mainly used on sensitive surfaces as, for instance, on steel sheet with surface coatings like paint, chrome, nickel, etc. Due to the rubber-type consistency of Santoprene©, the sensitive surfaces are protected against scratches (provided the surfaces are clean). Moreover, strong friction forces sideways for resistance to displacement are achieved due to the favorable friction coefficient of Santoprene©.
Please note: The systems' holding force is reduced proportionally to the not magnetic coat thickness of the sheet metals handled.
