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 51.4 (with Bore, with Rubber Jacket) → Page 2042 Information • Housing Steel, zinc plated • Materials of the magnet: - - Hard ferrite HF Temperature resistant up to 200 °C - - NdFeB ND Neodymium, iron, boron Temperature resistant up to 80 °C - - SmCo SC Samarium, cobalt Temperature resistant up to 280 °C • RoHS Specification 1 • Holding Disks GN 70 → Page 2072 • Adhesive Disks GN 70.1 → Page 2073 • Rubber Caps GN 70.2 → Page 2074 Accessory 2 3 4 4 d 1 Tolerances h Tolerances d 2 d 3 d 4 d 5 t Nominal magnetic forces in N HF ND / SC HF ND SC HF ND / SC HF ND / SC HF ND SC  10 - ±0,1  4,5 - ±0,1 - - 2,6 - -  5,2 - - -  19 -  13 - ±0,1  4,5 - ±0,1 - - 3,5 - -  6,6 - - -  40 -  16 ±0,1 ±0,1  4,5 +0,2/-0,1 ±0,1 ±0,1 3,5 3,5 -  7 6,6 - -  14 75 57  20 ±0,1 ±0,1  6 +0,2/-0,1 ±0,1 ±0,1 4,3 4,5 - 10 9,3 - -  27 105 81  25 ±0,1 ±0,1  7 +0,3/-0,2 ±0,2 ±0,1 5,5 4,5 - 12    9 - -  36 160 105  32 ±0,1 ±0,1  7 +0,3/-0,2 ±0,2 ±0,1 5,5 5,5 - 12   11 - -  72 310 235  40 +0,2/-0,1 ±0,1  8 +0,4/-0,2 ±0,2 ±0,1 5,5 5,5 -13 10,3 - -  90 500 540  47 - +0,2/-0,1  9,2 - ±0,3 - - 8,5 - - 17,3 -  - - 740 -  50 +0,2/-0,1 - 10 +0,5/-0,2 - - - -  8,5 - - 22 8,5 180 - -  57 +0,2/-0,1 - 11 +0,5/-0,2 - - - -  6,5 - - 24 9  230 - -  63 +0,3/-0,1 - 14 +0,5/-0,2 - - - -  6,5 - - 24 12  290 - -  80 +0,3/-0,1 - 10 +0,5/-0,2 - - - -  6,5 - - 32 8  450 - -  80 +0,3/-0,1 - 18 +0,5/-0,2 - - - -  6,5 - - 11,5 15  540 - -  83 +0,3/-0,1 - 18 +0,5/-0,2 - - - - 10,5 - - 32 15  600 - - 100 +0,5/-0,1 - 22 +0,5/-0,2 - - - - 10,5 - - 34 18  680 - -
