Raw magnets / SmCo, NdFeB / GN 55.2

GANTER

Raw magnets GN 55.2 are unshielded disc-shaped magnets.
Owing to their vast range of different magnet materials and sizes, they are suitable for virtually universal use. They are mostly attached by gluing.
When used without air gap, individual raw magnets always have lower adhesive forces than a magnet system in which shielding and magnetic return enormously intensify the force acting at the adhesion surface. Depending on the air gap between magnet and mating component, individual raw magnets - unlike magnet systems - can have substantially higher adhesive forces.
In the event that no suitable retaining magnets / magnet systems are available, raw magnets may be used in combination with appropriate holding constructions to build up highly specific magnet systems.

Samarium-Cobalt Magnet Ring Type

MAGNA

Resistant to demagnetization at temperatures as high as 350℃ and resistant to rust, making this a perfect component of medical devices and sensors. There are some issues with respect to mechanical strength, but miniaturization and weight reduction of the product can be achieved like the neodymium product.

Retaining magnets, with bore, Stainless Steel

GANTER

Stainless Steel-Retaining magnets GN 50.45 are a shielded magnetic system.
Owing to the lower magnetic conductivity of the stainless steel housing, the adhesive forces are lower than in steel.
To ensure that the magnetic properties (adhesive forces) are not impaired, the fixing screws must be made of non-magnetic material.

Samarium-Cobalt Magnet Round Type

MAGNA

Ideal for medical devices and sensors thanks to good coercivity at temperatures as high as 350 ℃ and corrosion resistance. Mechanical strength can pose some issues, but product miniaturization and weight reduction can be achieved, as with neodymium magnets.

Ring‑Shaped Samarium-Cobalt Magnet

Ring‑Shaped Samarium-Cobalt Magnet【10 Pieces Per Package】

NEOMAG

[Features]
· Temperature changes for the magnetic force are minimal, making it suitable for use in applications requiring temperature stability or in high temperatures.
· The magnet materials do not easily rust so surface treatments such as plating, etc. are not normally necessary.
· There is high demand for this magnet in compact magnetic sensors, micro switches, small relays, optical communications and laser devices.
· They are particularly suited for uses requiring temperature stability.
· There is no attraction force measurement data available for the model numbers listed below. Thank you for your understanding.

Samarium-Cobalt Magnet Bar Shape

MAGNA

Resistance to demagnetization at temperatures as high as 350℃, as well as resistance to rust, make this a perfect component for medical devices and sensors. There are some difficulties in terms of mechanical strength, but miniaturization and weight reduction of the product can be achieved similar to neodymium products.

[Features]
· The unprecedented strength of the neodymium magnet with polyamide coating (powder coating) greatly improves the environment‐resistant characteristics compared with conventional plated products.
· Even after a 2, 000-hour salt spray test, durability is not compromised.
· Superior durability against cracks and chips thanks to the cutting-edge coating technology.
· Suitable for various applications because mold cases are not required and the design is highly flexible.
· Optimal for products that require direct contact with the skin, such as clothing, bags, toiletries, and kitchen and household products.

Retaining magnets, smooth finish, Brass

GANTER

Retaining magnets GN 54.1 are a shielded magnetic system.
The configuration of magnetic and iron poles is known as sandwich magnet system. These retaining magnets deliver ultimate holding power, also with smaller workpieces.
Attachment options include pressing in or gluing in.
* k1 is the maximum dimension by which the retaining magnet can be shortened without losing its properties.
** Mounting these retaining magnets directly in steel components will create a magnetic shortcircuit which reduces the retaining power by as much as 15%. To avoid this effect, the spacings k2 between brass jacket and steel component should be observed. These spacings should also be maintained if the retaining magnet is shortened.
