What makes your iPhone 12 case compatible with MagSafe? Apple explains

Apple last month launched the iPhone 12 series and special MagSafe accessories that work with magnets to offer a new experience. However, the Cupertino giant doesn’t want to be limited to the only source bringing MagSafe accessories for the latest iPhone family, allowing third-party accessory makers to build new cases, covers, and other add-ons for the new iPhone 12 models. Apple has updated its accessory design guidelines, which outlines all of the key requirements accessory companies must meet in order to provide MagSafe compatibility for their products. The guidelines are also helpful in determining if the case or accessory you are purchasing for your iPhone 12 is compatible with Apple’s MagSafe.

Apple’s accessory design guidelines perform Certain rules that accessory manufacturers must follow in order to enable the new snap-on experience through MagSafe technology. The enclosures with MagSafe support must have a uniform maximum thickness of 2.1 mm. However, Apple recommends a thickness of 2.0 mm according to the updated guidelines noticed from a Twitter user.

The enclosures with MagSafe support should also be firmly attached to the device without relying on the magnets. In addition, there should not be any additional magnets on the back of the case – except for the magnets that support MagSafe technology.

It’s also important to note that third-party cases should work with the Apple MagSafe Charger and the iPhone Leather Wallet that Apple introduced along with the iPhone 12 series last month. This aims to provide lag-free wireless charging and ensure that the magnetic field on the case does not interfere with the magnetic stripe cards in the connected wallet.

On the mechanical side, Apple says that all of the magnets in the MagSafe case magnet array should be positioned in the same plane and that the case and MagSafe case magnet array should allow MagSafe accessories to magnetically self-align within a radial maximum of 1.55mm. The MagSafe case magnets should also be Neodymium-Iron-Boron (N45SH NdFeB) magnets with a NiCuNi coating or similar finish between seven and 13 microns.

The third-party case attached to the device should also require between 800 gf and 1,100 gf of magnetic force to remove a MagSafe accessory. Apple has also indicated two different ways the magnetic ring should be embedded in the case in order to work with MagSafe accessories.

Following the updated guidelines is mandatory for accessory manufacturers who mark MagSafe compatibility on their accessories. This indicates that Apple wants to expand the ecosystem around MagSafe by bringing reliable accessories and cases from third parties to the market – in addition to the in-house silicone case with MagSafe, the clear case with MagSafe, the iPhone leather wallet with MagSafe and the MagSafe- Charger.
