Technical Data for Retaining Magnets and Raw Magnets

Construction and Versions:
The document outlines different magnet types, including rubber-encased magnets for surface protection, unshielded systems with divided magnetic faces, and shielded systems with isolated magnetic cores. Pot magnets have a single magnetic face, while raw magnets are unshielded with all faces magnetic.

Properties:
Magnets may experience mechanical changes due to heat or chemical stress, but functionality is typically unaffected. Materials such as Hard Ferrite, AlNiCo, SmCo, and NdFeB are detailed, highlighting their magnetic force, remanence, retention force, mechanical strength, corrosion resistance, and temperature stability.

Mounting Instructions:
For shielded pot magnets, magnetic forces are minimum values achieved by vertical pull-off and full face contact. Clean pole faces are recommended to avoid decreased magnetic force due to air gaps and non-magnetic barriers.

Material and Assembly:
Magnets are made from materials like NdFeB and AlNiCo, with versions electro zinc-plated or bright. They can be mounted by press-fit, screwing-in, or gluing. Temperature stability varies, with some magnets stable up to 450°C.

Order Specifications:
Detailed order numbers, dimensions, and magnetic forces are provided for various magnet types, including disc, block, bar, and pot forms. Tolerances and assembly methods are specified for each type.

Special Notes:
Magnets with SmCo cores are suitable for spot-welding machines due to their resistance to demagnetization. Hairline cracks in certain magnets do not impair function.

Conclusion:
The document provides comprehensive technical specifications and guidelines for various magnet types, emphasizing clean contact surfaces and understanding the effects of air gaps and non-magnetic barriers on magnetic force.

Catalog excerpts

Technical data for retaining magnets and raw magnets Construction: Pot magnets are magnetic systems that, due to their technical structure have only one magnetic face. Unlike raw magnets, pot magnets only exert a magnetic force on one face. This design enables the spatial effect of the magnetic field to be limited. This prevents unwanted magnetisation of workpieces or machine elements by the pot magnet. Raw magnets are not magnetic systems, all the faces are magnetic. Version: Shallow pot magnet: The magnetic core is moulded or pressed into a housing. There is a non-magnetic barrier between the...

Magnetic strengths: The indicated magnetic forces are minimum values which are achieved by a vertical pull-off and full face contact. By dirty pole faces or uneven workpieces, air gaps are formed which sharply decrease the magnetic force. In general, the attractive force of a magnet decreases as the air gap increases. It is therefore advisable to always ensure a clean pole face and clean it from time to time. Non-magnetic barriers have the same effect as air gaps. magnetic strength % Mounting instructions for shielded pot magnets without pins 1. correct permanent magnet non-magnetic sleeve Non-magnetic...
