GN60 Button Type Magnet, Through Bore, Unshielded
GN 60 Button Type Magnet, Through Bore, Unshielded
Button magnets are a simple, cost effective & long lasting means of securely holding items in place. They have a split adhesive surface. They are a non-shielded magnet made by a casting method. The poles in a button magnet are at each side of the magnet surface, separated by a groove. Because they are made from one piece of material, they are unaffected by differential expansion or contraction making them more suited to some higher temperature applications than pot magnets. It should be noted that they are not as powerful as the equivalent pot magnet but they do attract over a further distance.
There is a through bore for fixing in place. To ensure that the magnetic properties (adhesive forces) are not impaired, the fixing screws must be made of non-magnetic material.
For easier handling and/or to avoid demagnetisation, these magnets have an iron plate on their adhesive surface.
