For diameter d 1 ≥ 50 the adhesive surface is lagged with an all over plastic cover. To ensure that the magnetic properties are not impaired negatively, the fixing screws should be made of non-magnetic material, like for example stainless steel, brass or plastic. see also... • More Information to Retaining Magnets → Page 2028 • Retaining Magnets GN 51.5 (with Internal Thread) → Page 2041 Information • Housing Steel, zinc plated • Material of the magnet NdFeB ND Neodymium, iron, boron Temperature resistant up to 80 °C • Plastic cover Technopolymer (Polyamide PA) • Plastic Characteristics → Page 2158 • RoHS Specification 1 • Holding Disks GN 70 → Page 2072 • Adhesive Disks GN 70.1 → Page 2073 • Rubber Caps GN 70.2 → Page 2074 Accessory
