Neodymium magnetic holders: power and application
Which magnetic holder should I choose?
Start with the connection and load direction, then check the specifications of the individual holder. The magnet rating does not establish the strength of the whole assembly.
| Choose for | Check before ordering | Next step |
|---|---|---|
| A matching screw | Internal thread size and screw engagement. | Internal threads |
| An existing threaded fixing | External thread size and the mating component. | External threads |
| Frequent hanging and removal | Hook attachment and the direction of the load. | Hooked holders |
| Painted steel | Surface condition, rubber coating and the product rating. | Rubber-coated holders |
Types of holders: threaded, hooked, rubber-coated and countersunk
An internally threaded holder takes a screw; an externally threaded one fits a matching component. A hook makes frequently removed items easier to hang. A rubber-coated housing is useful on painted surfaces, subject to the operating conditions of the specific product. A countersunk hole seats the screw head. The range also includes through-hole, channel and fishing models. Compare diameter, thread and the way the holder joins the structure before ordering.
How to choose pull force for the load
Read the pull rating together with the measurement conditions on the product card. Steel thickness and condition, air gaps, coatings and load direction all matter. An item on a vertical wall can slide even when its perpendicular pull rating appears sufficient. Allow a margin for your use and check the limits of the screw, hook or rope as well. Where a falling item could cause harm, add mechanical protection.
Applications in warehouses, workshops and industry
A holder can position a lamp, sensor or sign on steelwork in a workshop. A hooked model can temporarily suspend a sign or light equipment in a warehouse. Industrial selection depends on the substrate, force direction and operating conditions. Magnetic welding angles position steel parts during assembly; a channel model may suit frequently moved items. Compare each application with the specifications of the selected product.
Installation and safety
A magnetic holder is not a certified load-safety device. Do not suspend loads above people or use it for fall protection. Check the surface, joints and operating conditions, and add a mechanical safeguard where vibration or impacts are possible. For components built into equipment, see neodymium magnets; for removing contamination from material, see magnetic separators. Discuss food-contact or other special requirements individually.
Choose the holder for the specific load, substrate and working conditions. Check the product card before use and add mechanical protection where a falling item could cause harm.
