This special design is also known by the name “sandwich magnet” or “pole shoe magnet”. The retaining magnets are easy to fasten securely by pressing, shrinking or gluing. * k 1 is the maximum dimension by which the retaining magnet can be shortened without losing its properties. ** Mounting these retaining magnets directly in steel components will create a magnetic shortcircuit which reduces the retaining power by as much as 15%. To avoid this, the distance k 2 should be maintained bet- ween the brass housing and steel part or installation hole. This distance should also be maintained if the retaining magnet is shortened. see also... • More Information on Retaining Magnets → Page 2028 • Retaining Magnets GN 52.1 (without Bore) → Page 2056 Information • Housing Brass • Materials of the magnet: - - SmCo SC Samarium, cobalt Temperature resistant up to 200 °C - - NdFeB ND Neodymium, iron, boron Temperature resistant up to 80 °C • Identification of ND: Magnetic area colored blue • RoHS Specification 1 • Holding Disks GN 70 → Page 2072 • Adhesive Disks GN 70.1 → Page 2073 • Rubber Caps GN 70.2 → Page 2074 Accessories • Housing in stainless steel • Pols in stainless steel • Higher magnetic forces • Temperature resistance up to 280 °C On request
