All new iPhone 12 models come with MagSafe, which uses a magnet on the back of the phone for users to attach accessories to it. Apple today updated the Accessory Design Guidelines to include more details on how accessory manufacturers must implement MagSafe technology in their products.
Apple has the Extended Accessory Design Principles that provide instructions for other companies to make certified accessories for iPhones, iPads, Apple Watch, and other products. These guides have been updated today with some interesting new details about the MagSafe technology built into the iPhone 12.
In a recently uploaded PDF, the company revealed the specifications that the “Made for MagSafe”; cases must follow. This includes covering the entire device with a maximum thickness of 2.1 mm – although Apple recommends building 2.0 mm thick cases.
Case manufacturers must also ensure the accessory works with both the MagSafe Charger and the iPhone Leather Wallet. The case magnet should align properly with the magnet behind the iPhone, and Apple says the MagSafe case can’t have any other magnets.
All magnets that are part of the series of MagSafe shell magnets must be positioned on the same plane. The case’s magnet array and MagSafe will allow the MagSafe accessories to self-align magnetically within a maximum radius of 1.55 mm.
Apple requires MagSafe accessories using N45SH NdFeB magnets with 7-13μm NiCuNi coating. Users can also remove the MagSafe accessory by applying a force level of between 800 and 1,100 gf (grams force).
