ELESA+GANTER GN 50.4-ND-20 Magnet

Ganter GN 50.4-ND-20 Retaining Magnet

Description

This is a Ganter GN 50.4 retaining magnet, often referred to as a pot magnet. It features a Neodymium (NdFeB) magnet embedded in a steel pot, which shields and concentrates the magnetic field onto the holding surface. This design provides a strong holding force in a compact size. The countersunk central bore is designed for easy and secure mounting with a standard screw.

FAQ

Question?

What type of screw should be used for mounting the GN 50.4-ND-20 magnet?

Answer:

This magnet is designed with a countersunk bore suitable for a standard countersunk head screw. For the 20mm diameter version, a size M4 screw is recommended for a secure, flush fit.

Question?

What is the maximum operating temperature for this Neodymium magnet?

Answer:

The GN 50.4-ND version with Neodymium (NdFeB) magnet material has a maximum operating temperature of 80 deg C (176 deg F). Exceeding this temperature can lead to a permanent loss of magnetic force.

Question?

Does the steel housing affect the magnetic field?

Answer:

Yes, the steel pot housing serves a specific purpose. It shields the magnetic field on the back and sides while concentrating it on the open holding surface. This significantly increases the holding force compared to an unshielded magnet of the same size.
