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.
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, 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.
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).

NOTES
1. Based on regulations regarding
insulation distance, there is a restriction
on same-channel load connections
between terminals No. 2, 3 and 4, 5, as
well as between No. 8, 9 and 10, 11. See
the figure below for an example.
