GN 51.4 Retaining magnets technical informations Specification Disc-shaped, with bore, with rubber jacket Steel part, zinc-plated Rubber jacket, Elastomer (TPE), 73 shore, black Material of the magnet Neodymium, iron, boron NdFeB ND, temperature resistant up to 80C Features and applications Retaining magnets GN 51.4 are a shielded magnetic system with rubber jacket. The rubber jacket protects sensitive surfaces from being damaged by the magnet and also delivers a higher friction coefficient, resulting in high lateral adhesion forces.
