Apple Provides Design Guidelines for MagSafe Accessories

About Apple’s New iPhone 12 Charging Technology

All of the ‌iPhone 12‌ models have a ring of magnets built into the back around the wireless charging coil that adhere to MagSafe-based accessories like cases and chargers, which can be compatible with magnetic accessories such as mobile phone cases, chargers, and wallets. Apple produces its own MagSafe accessories, but third-party companies can also design MagSafe products.

Design guidance for phone case with MagSafe.

Apple has an accessory design guide that details the types and directions of magnets that accessory manufacturers can use, as well as other design details that Apple requires.

For example, a mobile phone case using MagSafe magnets must enclose the device with a maximum thickness of 2.1mm and must be firmly attached to the device instead of relying on magnets, which means that magnetic snap-on mobile phone cases cannot be used, otherwise they cannot be used with iPhone Stay connected.

There is a scene in Apple’s own iPhone 12 advertisement. Using MagSafe magnets, the phone case seems to be able to “click”. But in reality, the first-party and third-party phone cases do not have such a function. Apple does not plan to do so.

The content of the design file is very informative, with a specific position, size, and polarity instructions. So that all MagSafe accessories can be magnetically self-aligned “within a radial maximum of 1.55mm”. A mobile phone case with a magnetic array can neither interfere with wireless charging nor with the magnetic stripe card in the attached iPhone wallet. Apple has a special test protocol for manufacturers to use.

In addition, the magnet array supplier also recommends and has requirements for the magnets used. Apple requires that the magnet array must be N45SH neodymium iron boron, and the coating is 7μm-13μm NiCuNi. There are specific guidelines for the magnetic force, make sure the accessory does not fall off. Apple said that the phone case connected to the iPhone 12 needs at least 800 gf (gram force) to fall off, and the maximum is 1100 gf.

If the accessory manufacturer wants to put a label on the accessory. Indicating that the accessory is a MagSafe device, it must follow Apple’s guidelines. Friends who are interested in reading more about Apple’s guidelines can contact us for a complete PDF file.
