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.

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.

HOW IT WORKS

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.

(single side stable type)

THE VARIETY OF CONTACT

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.

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

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).

ARRANGEMENTS

4 A CAPACITY,

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

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.

TYPICAL APPLICATIONS

Telecommunications equipment, data

processing equipment, facsimiles, alarm

equipment, measuring equipment.

Matsushita Electric Works, 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.
