MagSafe, which is a technology that uses magnets on the back of the phone to let users attach accessories to it, comes with all the new iPhone 12 models. To include more details about how accessory manufacturers could implement MagSafe technology in their products , Apple today updated its Accessory Design Guidelines.
Apple has detailed Design Guidelines for Accessories that include guidelines for other businesses to create certified accessories for iPhone, iPad , Apple Watch, and other products. With some fascinating new information about the MagSafe technology built into the iPhone 12, these guidelines have been revised today.
The company revealed the specifications that “Made for MagSafe” cases must meet in a recently uploaded PDF file. This includes enclosing the whole device with a maximum thickness of 2.1 millimeters, while Apple recommends 2.0 millimeters of thickness for building cases.
Case manufacturers will have to make sure both the MagSafe Charger and the iPhone Leather Wallet work with the accessory. Case magnets must align properly with the rear iPhone magnets, and Apple says no other magnets can be used in MagSafe cases.
To use N45SH NdFeB magnets with a 7-13μm NiCuNi coating, Apple includes MagSafe accessories. By applying a force level of between 800 and 1,100 gf (gram force), users should also be able to remove a MagSafe accessory.
Apple also specifies that MagSafe cases do not rely on magnets to be securely attached to the device, as stated by MacRumors, which makes even some official iPhone 12 videos seem contradictory, as the company indicates that the cases are also magnetically attached to the iPhone 12.
Of course, accessory manufacturers willing to offer a MagSafe case or charger certified by Apple must follow all the guidelines given in the PDF file that you can read here.
