To avoid negatively impacting the magnetic properties, the fastening screws should be made of a non-magnetic material such as stainless steel, brass or plastic. see also... • More Information to Retaining Magnets → Page 2028 • Stainless Steel Retaining Magnets GN 50.45 (with Bore) → Page 2038 • Raw Magnets GN 55.1 (with Bore) → Page 2068 • Retaining Magnets GN 51.5 (with Internal Thread, with Rubber Jacket) → Page 2041 Information • Housing Steel, zinc plated • Materials of the magnet: - - Hard ferrite HF Temperature resistant up to 200 °C • RoHS Specification 1 2 3 4 d 1 h d 2 d 3 Nominal magnetic forces in N 25 ±0,1  7 +0,3/-0,2 M 4 -  5,2  36 32 ±0,1  7 +0,3/-0,2 M 4 -  5,2  75 40 +0,2/-0,1  8 +0,4/-0,2 M 4 -  5,2  90 50 +0,2/-0,1 10 +0,5/-0,2 M 6 M  8 12 170 63 +0,3/-0,1 14 +0,5/-0,2 M 8 - 13   290 80 +0,3/-0,1 10 +0,5/-0,2 M 8 - 12 450 80 +0,3/-0,1 18 +0,5/-0,2 M 8 M 10 14,5 550 1 Material of the magnet 2 d 1 3 h 4 d 2 1 2 3 4 GN50.4-HF-32- 7 -M4 How to order • Holding Disks GN 70 → Page 2072 • Adhesive Disks GN 70.1 → Page 2073 • Rubber Caps GN 70.2 → Page 2074 Accessory
