Sandwich Magnet, assemblied with steel plates and ferrite magnets or ndfeb magnets, are usually used in door latchs, mounting displays, signs, mounts, etc. Those sandwich magnets have strong holding force. Magnetic strength can be multiplied by up to 32 times by using steel armatures to concentrate magnetic flux. Such armatures may take the form of backing plates, channels or cups. The maximum increase in power is obtained when magnets are sandwiched between two plates. Custom-sized sandwich magnetic assemblies can be produced on demands. All other round bases, channels and sandwiches assembly magnets are available as well.
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.
Material: Steel Parts, Ceramic Magnets or Neodymium Magnets as per requirements
Surface Treatment: Zinc or NiCuNi-plating, Color Paiting Steel Plate.
Max Working Temperature: 200℃
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.
Magnetic Sandwich Assemblies
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.
