They are mostly attached by gluing. blank When used without air gap, individual raw magnets always have temperature resistant up to 200 °C lower magnetic forces than a magnet system in which shielding and -- NdFeB ND magnetic return enormously intensify the force acting at the adhesiNeodymium, iron, boron on surface. Depending on the air gap between magnet and mating nickel-plated component, individual raw magnets - unlike magnet systems - can have temperature resistant up to 80 °C substantially higher magnetic forces. • RoHS 3.8 1 In the event that no suitable retaining magnets / magnet systems are available, raw magnets may be used in combination with appropriate holding constructions to build up highly specific magnet systems. 3.9 Specification 3.5 h ±0,1 3.6 2 d ±0,1 3.4 3.3 3.2 3.1 disc-shaped, without bore On request • in other dimensions • made of hard ferrite (HF) see also... • More information to raw magnets → Page 1380 ff.
