S 2a2b/3a1b/4a 4A polarized power relays RoHS compliant FEATURES 1. Compact with high sensitivity The high-efficiency polarized electromagnetic circuits of the 4-gap balanced armature and our exclusive spring alignment method achieves, with high-sensitivity in a small package, a relay that can be directly controlled by a driver chip. 2. Strong resistance to vibration and shock Use of 4G-BA technology realizes strong resistance to vibration and shock. 3. High reliability and long life Our application of 4G-BA technology, along with almost perfectly complete twin contact, ensures minimal contact bounce and high reliability. 4. Ability to provide wide-ranging control Use of 4G-BA technology with goldclad silver alloy contacts in a twin contact structure enables control across a broad range from microcurrents of 100 A 100 mV DC to 4 A 250 V AC. 5. Latching types available With 4G-BA technology, as well as single side stable types, convenient 2 coil latching types for circuit memory applications are also available. 6. Wide variety of contact formations available The compact size of the 4G-BA mechanism enables the provision of many kinds of package, including 2a2b, 3a1b, and 4a. These meet your needs across a broad range of applications. S RELAYS 7. Low thermal electromotive force relay High sensitivity (low power consumption) is realized by 4G-BA technology. Separation of the coil and spring sections has resulted in a relay with extremely low levels of thermal electromotive force (approx. 0.3 V). 8. DIL terminal array Deployed to fit a 2.54 mm .100 inch grid, the terminals are presented in DIL arrays which match the printed circuit board terminal patterns commonly in international use. 9. Relays that push the boundaries of relay efficiency High-density S relays take you close to the limits of relay efficiency. 10. Sockets are available. TYPICAL APPLICATIONS Telecommunications equipment, data processing equipment, facsimiles, alarm equipment, measuring equipment. 4-GAP BALANCED ARMATURE MECHANISM 1. Armature mechanism has excellent resistance to vibration and shock The armature structure enables free rotation around the armature center of gravity. Because the mass is maintained in balance at the fulcrum of the axis of rotation, large rotational forces do not occur even if acceleration is applied along any vector. The mechanism has proven to have excellent resistance to vibration and shock. All our S relays are based on this balanced armature mechanism, which is able to further provide many other characteristics. 2. High sensitivity and reliability provided by 4-gap balanced armature mechanism As a (polarized) balanced armature, the S relay armature itself has two permanent magnets. Presenting four interfaces, the armature has a 4-gap structure. As a result, the rotational axis at either end of the armature is symmetrical and, in an energized into a polarized state, the twin magnetic armature interfaces are subject to repulsion on one side and attraction on the other. This mechanism, exclusive to Panasonic Corporation, provides a highly efficient polarized magnetic circuit structure that is both highly sensitive and has a small form factor. Moreover, suitability for provision with many types of contact array and other advantages promise to make it possible to provide many of the various characteristics that are coming to be demanded of relays. HOW IT WORKS (single side stable type) 1) When current is passed through the coil, the yoke becomes magnetic and polarized. 2) At either pole of the armature, repulsion on one side and attraction on the other side is caused by the interaction of the poles and the permanent magnets of the armature. Panasonic Corporation 3) At this time, opening and closing operates owing to the action of the simultaneously moulded balanced armature mechanism, so that when the force of the contact breaker spring closes the contact on one side, on the other side, the balanced armature opens the contact (2a2b).
