If there is something that characterizes Apple, it is the quality, not only of the products themselves and the materials used, but also of the technology designs they use. Seeing an iMac or MacBook inside is a small work of art. And to comply with the standards imposed by the company, it is important to follow their guidelines. This is why Apple has updated your accessory design guide for design accessories compatible with the new MagSafe.
With the launch of the iPhone 12 Apple has incorporated MagSafe, the wireless charger with a magnetic system to never fail, so that whenever you put your smartphone above you find it with a full battery. But for third parties to create MagSafe-compatible chargers or cases, the strict details established by Apple must be taken into account.
Apple thoroughly sets out how to make accessories compatible with its products in the Accessories Design Guide.
So if you are a manufacturer of accessories and If you want to get the “Made for MagSafe” seal, you should, for example, not exceed 2.1 mm. of thickness, although Apple itself recommends not to exceed 2 mm. It also shows a special emphasis not only on the number, but also on the position of the magnets, to match those of the iPhone.
In fact, Apple’s precision when designing its technology is such that the position of the magnets has to allow compatible accessories self-align within a maximum radial 1.55mm.
Magnets used in accessories for MagSafe must be neodymium N45SH NdFeB
And to achieve all this, the company establishes the material of the magnets that must be neodymium magnets N45SH NdFeB coated with a 7-13 μm NiCuNi layer. It also specifies that users should not apply more than 800-1100 gram-force to detach the accessories.
For all these specs it is important or convenient to use Apple’s own products or at least that the company has authorized and approved. We will avoid problems derived from poor manufacture of accessories. And if you are a manufacturer, you know, do not forget to read in detail the Apple Accessories Design Guide.
