Plating: Nickel / Zinc
Channel magnet gets its name exactly from its structure. It shares the same working principle with round shape pot magnet that conduct magnetic field strength via the steel channel to have alternating-pole pattern on the holding face so that high holding force can be obtained.
This NdFeB channel magnet has a through hole in the center and it can be fastened at places where the space is limited, but high holding force is needed. NdFeB is strong rare earth magnet and the special construction of the channel enhances its performance with higher force. That’s why this small channel magnet can give a holding force up to 15kg.

WHAT ARE CHANNEL MAGNETS AND WHAT ARE THEY USED FOR?
Channel Magnetic Assemblies are created using ceramic magnets clad in a steel channel. Magnetic strength can be multiplied by up to 32 times by using steel armatures to concentrate magnetic flux. Such armatures may take the form of backing plates or channels. The maximum increase in power is obtained when magnets are sandwiched between two plates.
For example: A 0.187″ thick x 0.750″ wide x 1″ long rubber magnet has 4 oz. of pull strength. The same magnet bonded to a channel assembly will pull 5 Ibs., which is 20 times greater.
Common Applications: Sign and Banner Holders – License Plate Mounts – Door Latches.
U-CHANNEL NDFEB MAGNET WITH COUNTERSUNK HOLES
Our Neodymium and Ferrite channel magnets with are encased within a secure steel shell, with either countersunk or through hole fixing and are extremely versatile for use in mounting or securing, in door latches and for holding signage and banners.
Channel Magnet Features
These rectangular base magnets channel great holding strength onto one large surface. A strong ceramic or rubber magnet is set into a plated steel channel with holes, loops or threaded nuts for mounting.
Common applications
• Door latches
• Vehicle license plate holders
• Blueprint holders
• Sign and banner holders
Holding and pull strength
Channel assemblies are up to 32 times stronger than ceramic magnets by themselves. Pull strength is tested on a flat steel plate 3/8 inch thick. The pull may vary depending on the surface it is attracted to, for example, if the steel is less than 3/8 inch thick, coated, rough or rusty. We recommend that you obtain a sample to test and confirm the actual pull / holding capability when used in your application. Channel Holders Latch Ceramic Sandwich Magnets
Colors, packaging
Adams can produce rectangular magnet assemblies in just about any color. We can package them in individual bags or other the packaging types you specify.
Design and handling considerations
Most of our magnetic assemblies are made with ceramic magnets, which are brittle and may break if dropped or if riveting is used in their application. Please use caution when handling channel magnets assemblies, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that putting fingers in their path could prove painful.
