Neodymium Channel Magnet Assemblies w/Countersunk Holes for Mounting Applications

Neodymium rectangular channel magnets are powerful, U-shaped magnetic assemblies built for heavy-duty mounting, holding and fixing applications. They are constructed with strong neodymium block magnets encased in a nickel-plated steel channel for maximum holding power(up to 79 lbs). Channel magnets have one or two counterbore/countersunk holes for attaching M3 standard flat-head screws, nuts and bolts.

Neodymium channel magnets are stronger than ceramic channel magnets or standard neodymium block/bar shapes, as the steel channel concentrates most of the magnetic field to one side (the surface) of the magnet. They are plated with a triple layer of: Ni-Cu-Ni (Nickel+Copper+Nickel), using an electrolytic based process for maximum protection against corrosion and oxidation.

Channel magnets can be used in both indoor & outdoor applications, they are ideal for industrial & consumer mounting holding & fixing applications where high-magnetic strength is required.

Approximate Pull Info:

The approximate pull info listed is for reference only. These values are calculated under the assumption that the magnet will be attached to a flat, ground 1/2" thick mild steel plate. Coatings, rust, rough surfaces, and certain environmental conditions can significantly reduce the pull force. Please be sure to test the actual pull in your actual application. For critical applications, it is suggested that the pull be de-rated by a factor of 2 or more, depending on the severity of a potential failure. (top)

Manufacturing Methods

Our neodymium channel magnets are sintered for optimal magnetic strength and axially magnetized (the magnetism direction is along the axis of the magnet from the north to the south poles). (top)

Measurement Tolerances

Standard tolerances are +/- 0.005” on both diameter and thickness dimensions. (top)
