High sensitivity and reliability Panasonic Corporation, provides a highly resistance to vibration and shock provided by 4-gap balanced armature efficient polarized magnetic circuit The armature structure enables free mechanism structure that is both highly sensitive and rotation around the armature center of As a (polarized) balanced armature, the has a small form factor. Moreover, gravity. Because the mass is maintained S relay armature itself has two suitability for provision with many types of in balance at the fulcrum of the axis of permanent magnets. Presenting four contact array and other advantages rotation, large rotational forces do not interfaces, the armature has a 4-gap promise to make it possible to provide occur even if acceleration is applied structure. As a result, the rotational axis many of the various characteristics that along any vector.
