High sensitivity and reliability Panasonic Corporation, provides a highly 1. Armature mechanism has excellent provided by 4-gap balanced armature efcient polarized magnetic circuit resistance to vibration and shock mechanism structure that is both highly sensitive and The armature structure enables free As a (polarized) balanced armature, the has a small form factor. Moreover, rotation around the armature center of S relay armature itself has two suitability for provision with many types of gravity. Because the mass is maintained permanent magnets. Presenting four contact array and other advantages in balance at the fulcrum of the axis of interfaces, the armature has a 4-gap promise to make it possible to provide rotation, large rotational forces do not structure. As a result, the rotational axis many of the various characteristics that occur even if acceleration is applied at either end of the armature is are coming to be demanded of relays. along any vector. The mechanism has proven to have excellent resistance to symmetrical and, in an energized into a vibration and shock. All our S relays are polarized state, the twin magnetic based on this balanced armature armature interfaces are subject to mechanism, which is able to further repulsion on one side and attraction on provide many other characteristics. the other.
