4-GAP BALANCED ARMATURE MECHANISM

HOW IT WORKS (single side stable type)

2a2b/3a1b/4a 4 A

polarized power relay S RELAYS

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 gold-

clad 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.

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.

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, 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.

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.

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).
