High sensitivity and reliability Panasonic Corporation, provides a highly resistance to vibration and shock provided by 4-gap balanced armature efcient 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. The mechanism has at either end of the armature is are coming to be demanded of relays. 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. This mechanism, exclusive to ASCTB207E 201701-T 1S HOW IT WORKS (single side stable type) 1) When current is passed through the 3) At this time, opening and closing Repulsion coil, the yoke becomes magnetic and operates owing to the action of the Permanent magnet Attraction polarized. simultaneously moulded balanced Residual plate 2) At either pole of the armature, armature mechanism, so that when the Attraction repulsion on one side and attraction on force of the contact breaker spring closes Axis the other side is caused by the interaction the contact on one side, on the other Repulsion of the poles and the permanent magnets side, the balanced armature opens the of the armature. contact (2a2b).
