Clamping onto thin sheet could result in a reduced clamping force as the thin ferromagnetic sheet magnetically saturates. Clamping through an ‘effective air gap’ also significantly reduces the pull force. However, the temperature characteristics of the magnets, directly affect upon pull force (above ambient temperatures result in reduced pull forces – the amount of reduction depends on the magnet material in the Pot Magnet).
 
For marine applications, we have some specially designed pot magnets, which can resist any extreme-to-extreme temperature range for magnets. To provide strong pot magnet with much improved corrosion resistance, we have come up with new formula, which is a combination of ferromagnetic stainless steel with SmCo to provide a strong Pot Magnet with improved corrosion resistance and with a stable pull force over a very wide temperature range. The extreme performance characteristics make it a superb choice where the application has to work in extreme environments.

Ferrite Limpet Pots

Limpet Pot Magnets provide high performance and a low profile. The pot magnet incorporates a ferrite magnet to give a superior hold on surfaces which are dirty and uneven. Common applications include holding back doors and gates or any other application which needs a solid, positive and reliable magnetic grab.
Maximum operating temperature: 180C.
