Custom Series · Magnetic
"N52 magnets" is on almost every magnetic case listing and it is not the number that decides whether a wallet stays put. Geometry, panel thickness and retention matter more than the grade — and on foldables, placement is the whole game.

| Factor | Spec we hold | Why |
|---|---|---|
| Array geometry | Ring plus alignment magnet, official layout | A correct ring with no alignment magnet lets accessories rotate |
| Ring offset | ≤ 1.0 mm | 1.5 mm still holds a wallet but measurably drops charging speed |
| Panel thickness over magnet | ≤ 1.2 mm | Force falls off sharply with distance; every 0.3 mm costs hold |
| Magnet retention | Over-moulded or bonded, never loose press-fit | Press-fit magnets break free after repeated drops |
| Grade | N52 in slim cases, N42 acceptable in thick shells | Higher grade buys force per millimetre, not force overall |
A card slot sits exactly where the ring wants to be; on a foldable the hinge occupies the centre line and the array must move to the lower panel; a steel kickstand over the magnet zone shunts the field. Each of our magnetic ranges resolves one of these, which is why the ring position differs between products.
Run these on a production sample, not a golden sample, and do not tell the supplier what you are testing.
Only when thickness is the constraint. N52 gives more force in less space; in a thick shell with room for a larger array, N42 can match the hold at lower cost.
Only if the array is misaligned or the back is too thick. Correct alignment supports full-rate charging.
No. Modern phones are designed around MagSafe-style accessories. The real risks are magnet retention and magnetic stripe cards.
Yes — the array is routed into the lower back panel, clear of the hinge flex.
