GN 51.6 magnets are a shielded magnetic assembly with rubber jacket.
They are especially suitable for applications where the surface is easily marred. Also, these magnets have an increased coefficient of friction, which creates high lateral retaining force.
Dimensions, especially drill hole spacing m and thread d2, match the clamp mounting units in series GN 473, GN 477 and GN 480.
Type ND temperature resistant to 175 °F (80°C).
