Page 2038 | 3.9 Holding with Magnets GN 50.45 Stainless Steel Retaining Magnets Disc-Shaped, with Bore Stainless steel retaining magnets GN 50.45 are combined with a stainless steel housing and a plastic ring / insulation ring into a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface. 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 50.25 (with Internal Thread) → Page 2034 • Stainless Steel Retaining Magnets GN 52.5 (with Threaded Stud) → Page 2061 • Retaining Magnets GN 51.4 (with Bore) → Page 2042 Information • Housing Stainless steel • Materials of the magnet: - - Hard ferrite HF Temperature resistant up to 220 °C - - SmCo SC Samarium, cobalt Temperature resistant up to 350 °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 1 Material of the magnet 2 d 1 3 h 4 d 3 (d 2 ) How to order 1 2 3 4 GN50.45-HF-50-10-8,5 2 3 4 4 d 1 Tolerances h Tolerances d 2 d 3 d 4 d 5 t Nominal magnetic forces in N HF SC HF SC HF HF SC HF SC HF SC HF SC 16 - ±0,1  4,5 - ±0,1 - - 3,5 - -  6 -  3 -  41 20 ±0,1 ±0,1  6 +0,2/-0,1 ±0,1 4,3 - 4,5 9,5  -  8 - 3,5 22  60 25 ±0,1 ±0,1  7 +0,3/-0,2 ±0,2 5,5 - 4,5 11,5 -  8 - 4 29  80 32 ±0,1 ±0,1  7 +0,3/-0,2 ±0,2 5,5 - 5,5 11,5 - 11 - 4 58 200 40 +0,2/-0,1 ±0,1  8 +0,4/-0,2 ±0,2 5,5 - 5,5 12,5 - 10,5 - 4 72 420 50 +0,2/-0,1 - 10 +0,5/-0,2 - - 8,5 - - 22 -  8,5 - 145 - 63 +0,3/-0,1 - 14 +0,5/-0,2 - - 6,5 - - 24 - 12  - 230 -
