NORELEM

Industrial magnets

Description

norelem magnets are available with different magnetic cores and bodies. Their magnetic cores are composed of the materials with permanent magnetic properties AlNiCo (aluminum, nickel and cobalt), NdFeB N35 (neodymium), hard ferrite or SmCo (samarium-cobalt).

Thanks to their technical structure, norelem magnets are distinguished by their contact surface, their effect of attraction/magnetic force (adhesion) and therefore by their use in industry.

Structure of a norelem industrial magnet using the example of the holding magnet

Magnetic cores differ, for example, in their heat resistance, demagnetization or magnetic adhesion/strength. Sheaths made of steel, stainless steel, aluminum or rubber protect the magnetic core and additionally support the operation of the magnet.

The shape of the magnets also plays an important role here. Depending on the application and area of use in industry, different shapes may be required, such as flat, round, angular, with or without drilling hole, U-shaped or rod-shaped.

In addition, magnets differ in their system. Norelem magnets can be acquired both with a shielded system, in which only certain points present a magnetism effect, and with an unshielded system, in which the entire surface presents a magnetism effect.

Technical details

Raw magnets

norelem raw magnets are universal and can be mounted by fitting, screwing or gluing. Raw magnets are always unshielded systems, so they are not magnetic systems. Therefore, all surfaces of raw magnets have a magnetism effect. Raw magnets are subdivided into disc magnets, disc magnets with drilling, rectangular magnets and cylindrical magnets.

The disc magnet from the raw magnet group is available both with drilling (the disc magnet can also be screwed and therefore securely attached) and without drilling in the norelem online shop. The disc magnet is made of NdFeB N35 (neodymium) and has a zinc-plated surface.

norelem cylindrical magnets are made of AlNiCo (aluminum, nickel and cobalt) and have the advantage of high heat resistance (max. temperature range 450 °C). Cylindrical magnets can be ordered with different lengths and diameters depending on requirements.

Rectangular magnets differ from disc magnets only in their shape. Their flat shape provides optimal conditions for simple and practical use of rectangular magnets in industry.

Round aluminum, nickel and cobalt magnets

These magnets have a permanent magnetic alloy core (AlNiCo) and a steel housing. The magnetic core is separated from the housing using a non-magnetic material, creating a shielded system. Fixing possibilities include press-fit, shrink-fit and gluing.

Round magnets are available as cylindrical stud magnets, with or without calibrated outer diameter . All round magnets are heat-resistant (up to max. 450°C), have high adhesion and are available in different versions.

Round neodymium and samarium-cobalt (SmCo) magnets

Here we distinguish cylindrical magnets with a magnetic core in NdFeB (neodymium) or SmCo (samarium-cobalt) . The magnetic core is protected by a brass housing with smooth surface, which creates a shielded system.

SmCo magnets are particularly suitable for use in direct contact with spot welding machines, as they are not likely to demagnetize.

Fine or precision polar pitch magnetic clamping blocks

norelem clamping blocks consist of a fine polar pitch magnetic system that can act on two to three separate surfaces at the same time. The finer the pole pitch, the thinner the clamped steel parts can be. The life of the magnetization of the clamping blocks is unlimited under the conditions prevailing in industrial production.

Magnets (flat magnets)

The magnetic core of flat magnets is embedded or fitted into a housing. A non-magnetic separation layer separates the magnet from the housing. Thus, flat magnets make it possible to obtain a shielded system.

Flat magnets are available with a hard ferrite, samarium-cobalt (SmCo) or neodymium (NdFeB) magnetic core. The difference is in their grip. Flat magnets with SmCo core have three to five times greater adhesion than flat AlNiCo or hard ferrite magnets. Flat magnets have a steel or stainless steel housing.

The norelem online store offers different versions of flat magnets: with or without thread, with thread, with hook, with countersunk hole or with countersunk hole.

Magnets (flat magnets) with protective rubber coating

The great advantage of flat magnets with protective rubber coating (TPE or synthetic rubber) is the protection of the magnetic core or sensitive surfaces of the magnets. Thanks to the protective rubber coating of the flat magnets, the coefficient of friction increases, thereby achieving a high lateral movement force.

The flat magnets with protective rubber coating are available with internal thread , with rectangular body (optimal adhesion on thin sheets with fragile surfaces) , with threaded sleeves , with threaded stud or with countersunk hole .

norelem offers rubber protective caps for flat magnets in its range of flat magnets. Protective rubber caps are positioned on the contact surfaces of the flat magnets. The moving force in the lateral direction is doubled and almost reaches the initial adhesion of the magnets. The protective rubber caps fit all flat magnets with a diameter of 50, 63 or 80 mm.

Reinforced magnets & button type magnets

Strong magnets are hard magnets with aluminum housing and steel casing. Reinforced magnets feature high heat resistance. Their cases are lacquered red. The reinforced magnet has a shielded system and is used for holding, lifting and mounting in equipment. In case of reduced space in equipment, flat reinforced magnets can be used.

The button type magnet, on the other hand, has a separate contact surface with a through-mounting bore. Button type magnets are mainly used in laboratories, for measurements and for holding metal objects.

U-shaped magnets

The red-lacquered U-magnets made from the permanent magnetic alloy AlNiCo have high adhesion, an unshielded system and are supplied with a zinc-plated cover plate. U-shaped magnets are used for holding, sorting and lifting.

Holding magnets

Holding magnets , whose magnetic core is made of hard ferrite, are often used on bulletin boards, whiteboards and magnetic boards. Their housing is made of plastic.

Accessories

In addition to a complete range of magnets, norelem also offers corresponding accessories.

The flexible magnet handle equipped with a brass hose and a plastic handle is mainly used for searching and removing steel parts from inaccessible places.

Permanent magnetic feet which can be plugged or unplugged and with black surface and high adhesion are used in equipment as holding magnets, holders, diamond stones, etc.
