* k is the maximum dimension by which the retaining magnet can be shorted without losing its properties.

Identification No.

  • No. 1: Tolerance d = ±0.1
  • No. 2: Tolerance d = h6

Housing

Steel

  • Identification No. 1: zinc plated
  • Identification No. 2: blank

Materials of the magnet:

AlNiCo AN

Aluminium, nickel, cobalt

temperature resistant up to 450 °C

NdFeB ND

Neodymium, iron, boron

temperature resistant up to 80 °C

Retaining magnets GN 52.1 are combined with a steel housing and insulation of brass/aluminum or plastic into a system that shields and strengthens the magnet for optimal transmission of the magnetic flux onto the magnetic surface.

The retaining magnets are easy to fasten securely by pressing, shrinking or gluing.
