PU substrate, not textile
The magnets are glued onto a flexible polyurethane film; the textile housing comes next.
Magnet Strips / Magnet Blocks
Strips to cut into Magnet Blocks.
Small NdFeB magnetic ceramics laid end to end on a PU substrate with silicone glue. The strip is cut to the useful length, then the Magnet Blocks slide into a pocket, a sheath or a dedicated housing.
Sized strength
The format, the cut length and the chosen grade determine the hold of the fastener.
Two complementary BAs
A fastener is built with two Magnet Blocks of the same length, active faces facing each other.
Nickel-freeDual zinc + epoxy coating, REACH-compliant: no substance of concern in contact with the skin.
8 to 10× more powerfulAlternating polarities multiply the hold compared with a single magnet of equal volume.
−50 °C to +90 °CWater, snow, sand, salt spray: estimated service life of over 20 years.
Flexible by constructionSmall magnets articulated on an elastomer binder: the band follows the shapes of the body.
Cut to length96 cm band to cut into Magnet Blocks, to the exact length you need.
BA catalog
Choose the strip format.
Magnet Strips are delivered in 96 cm lengths, then cut into Magnet Blocks at the useful length. The format sets the magnetised width, the strip width and the rows. All are documented in grade N40.

Magnetic grade
Documented in N40. Higher grades custom-made.
All BA formats are documented in grade N40 (NdFeB magnets): datasheets available, the recommended starting point for sampling. Grades N45, N48 and N52 exist as custom options and are qualified per project.
Power by grade
ref. N40 = 100%The grade sets the magnetic power: each step increases the attraction (around +15% per step, up to +28% at the maximum). The right grade mostly depends on the use case — substrate, gap between active faces and expected hold.
N40The recommended starting point to sample the four BA formats and validate the assembly.100 %
N45A higher-strength option when N40 lacks hold on the prototype or the final substrate.+12 %
N48An option to study for more demanding applications, validated on a real sample.+18 %
N52The most demanding range, reserved for cases where compactness and expected hold justify the trial.+28 %
The grade adjusts the strength of the fastener, not its size or appearance. In practice, start with N40 (documented), then move up in grade only if the hold measured on the prototype requires it.
Custom grade
Need a higher grade (N45 / N48 / N52)? We qualify it with you, case by case, in a call.
How to choose
Strength is built through cutting and assembly.
A fastener is made of two complementary Magnet Blocks. The cut length, the strip width and the thickness between active faces directly influence the result.
01
Choose the strip
The V04, V06, V08 or V12 format sets the magnetised width, the strip width and the number of rows.
02
Cut two BAs
The strip is cut to the useful length to obtain two complementary Magnet Blocks.
03
Insert into a housing
The BAs go into a pocket, a sheath or a housing built into the final product.
04
Validate the fastener
The hold depends on the format, the cut length, the grade and the thickness between active faces.
What you choose
You first choose a width — V04, V06, V08 or V12 — then a block length and a magnetic range to test.
What we validate
The final hold depends on the substrate, the thickness between magnets, the direction of the active faces and the care protocol.
Integration approaches
Choose the right family for your product.
Keep the same navigation principle across zips, strips, blocks, sheaths and custom developments.
