Description
Neodymium ring magnet 17.5 x 4.75 mm with plastic coating and countersink hole
Discover our 17.5mm diameter, 4.75mm tall neodymium ring magnet, designed for versatile use in both indoor and outdoor applications. This powerful magnet features a durable polypropylene plastic coating, providing additional protection against rust and wear. A countersunk hole allows for easy screw mounting, making it ideal for a variety of applications.
Unlike standard neodymium magnets, this variant is more resistant to moisture and external influences, making it perfect for outdoor applications such as on ships, in shipbuilding, bathrooms, and campers. The plastic coating reduces the risk of breakage, extending the magnet's lifespan and making it suitable for long-term use in demanding environments.
Technical description:
Volgens de door de fabrikant verstrekte conformiteitsverklaringen voldoet dit product aan de actuele Europese RoHS-richtlijn en REACH-verordening.

Neodymium magnets are very powerful and can bounce off each other and/or iron objects at high speed. The force increases as the magnet gets larger, which also increases the risk of breakage. Two of the larger magnets in our range are powerful enough to break fingers or at least cause a few large blisters.
Therefore, wear work gloves and keep magnets away from children. Also, keep Neodymium (NdFeB) magnets at a safe distance from people with pacemakers. This also applies to electronic devices and payment cards.
Neodymium magnets are still the most powerful magnets available today. Our super-strong magnets also remain magnetic virtually indefinitely, provided they are not exposed to the maximum operating temperature or are used with opposite poles.
The letters and numbers in the material coding have the following meaning: The N stands for Neodymium, the subsequent digits indicate the maximum magnetic energy expressed in MgOe. If there are no further letters after this, the magnet can be used up to 80 degrees Celsius.
If there are still letters behind it, it can reach a higher temperature.
We indicate adhesive force in grams or kilograms because this appeals to more people than Newton. The indicated force is measured perpendicular to the magnet. The adhesive force is the force required to pull a smooth, flat steel object (ST37) at least 10 millimeters thick from the magnet in question.
This force quickly diminishes when, for example, there's a gap or layer of paint between the magnet and the object. Even half a millimeter can reduce the force by half. A steel alloy or a rough surface also significantly reduces the holding force.
As mentioned, the direction of the adhesive force is perpendicular to the magnet, but the shear force is much smaller and also depends on the friction between the magnet and the object.
