Sandwich Assembly Features
A ceramic magnet is “sandwiched” between two plated steel pole pieces to form a powerful latch magnet assembly held together by glue or rivets.
Holding and pull strength
Magnetic assemblies are up to 32 times stronger than magnets by themselves. Pull strength is tested on a flat steel plate 1/2 inch thick. The pull may vary depending on the surface it is attracted to, for example if the steel is less than 1/2 inch thick, coated, rough or rusty. We recommend that you obtain a sample to test and confirm the actual pull / holding capability when used in your application. Tiny Ring Bulk Round Grade 8 Ceramic Holding Disc Magnets with Hole

Colors, packaging
Our stock sandwich assemblies are usually nickel plated. MPCO can produce sandwich assemblies in just about any color. We can package them in individual bags or other packaging types you specify.
Common applications
Money clips, Channel letter holders, Door latches
Design and handling considerations
Most of our magnetic assemblies are made with ceramic magnets, which are brittle and may break if dropped or if riveting is used in their application. Please use caution when handling sandwich magnets, their exceptional magnetic force may cause them to attract to metal (or to each other) so strongly that putting fingers in their path could prove painful.
