GN 51.2 Retaining magnets technical informations Specification Disc-shaped, with female thread, 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 80 Features and applications Retaining magnets GN 51.2 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.
