Type: Permanent
Composite: Neodymium Magnet
Shape: Rectangle
N35 Rectangle sintered NdFeB magnets are supplied in stock sizes varying from 3mm cubes up to 100mm x 50mm x 30mm and 50mm x 50mm x 25mm blocks. The stock sizes are supplied with +/-0.1mm tolerances. The pull forces vary from 0.7kg up to 88.5kg. The larger magnets can be very difficult to handle because of the very high pull forces that exist. For note the last dimension (with "mmA" as the ending) defines the direction of magnetisation. So, for a 5mm x 10mm x 2mmA magnet, the pole faces are 5mm x 10mm in size with 2mm being the distance between the pole faces of that magnet. The "A" in "mmA" means that direction of magnetisation is "Aligned" with the axis that the "A" has been put against.
There are multiple uses for such magnets. Because the larger magnets have very high pull forces, they are favoured for clamping applications, magnetic sweeper applications, and industrial applications, amongst others.
We can produceN35 Rectangle sintered NdFeB magnets in different sizes, different grades (strengths and temperature ratings), different coatings/finishes and with different directions of magnetisation as part of our custom magnet (made-to-order) service. For example, we can produce magnets as big as 150mm x 150mm x 30mmA and 200mm x 130mm x 30mmA.
Grades: N30-N54, N30M-N52M, N30H-N50H, N30SH-N45SH, N28UH-N42UH, N26EH-N38EH, N28AH-N35AH;
