GN 54.1 magnets are a shielded magnetic assembly.
The configuration of magnetic and iron poles is known as a sandwich magnet assembly. These retaining magnets provide superior holding power and work well with smaller workpieces.
Mounting options include pressing in or gluing in.
Type SC temperature resistant to 390°F (200°C), Type ND temperature resistant to 175 °F (80°C).

*k 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 short-circuit which reduces the magnetic power by as much as 15%. To avoid this effect, the k2 distance between the brass housing and the steel component should be observed. These distances should also be maintained if the retaining magnet is shortened.
