FEATURES
TYPICAL APPLICATIONS
1. Compact, slim design
Use of high-performance flat
electromagnetic design achieves
10.9 mm .429 inch profile, flat type thin
package. Slim type, with width of
11.2 mm .441 inch, enables high-density
mounting on PC boards.
2. High reliability
Provides stable contact pressure needed
for card lift-off contact driver method. The
use of Ac clad twin contacts provides
stable contact resistance and ensures
high contact reliability.
3. Compatible with all major safety
standards
UL and CSA certified, and complies with
Japanese Electrical Appliance and
Material Control Law.
1. Information processing and telecom
equipment such as computers and
terminal devices.
2. Gas hot air heating equipment and
air conditioners.
3. Timer, temperature controller and
other equipment that requires form
factor reduction.
4. Transmission and measuring
devices such as facsimile machines
and electronic counting devices.
5. Control panels for industrial
equipment such as machine tools,
factory automation devices, and NC
machines.

NOTES
1. Because the NC relay is polarized, the
positive “+” and negative “–” connections
to the coil should be done as indicated on
the wiring diagram. If connected
incorrectly, it may malfunction or fail to
operate.
2. As a 2 coil latching type, under the
stipulations of the Japanese Electrical
Appliance and Material Control Law,
because the terminals of NC relay coils
have an insulation distance of more than
1.5 mm, NC relays can be used in power
supply operating circuits of up to 100 V.
When used in contact circuits, 200 V is
the maximum voltage.
3. To maintain insulation between coils of
2 coil latching series, terminals 5 and 6
for flat series, and terminals 3 and 4 for
vertical series should be connected to
provide common return.

Figure 1 shows wiring that complies with
Japanese Electrical Appliance and
Material Control Law stipulations for
power supply circuits. At the copper
traces on PC boards, between terminals
3 and 4, as shown in Figure 2, apply
epoxy resin (to thickness of more than 3
mm) or similarly adhesive to provide
insulation.
4. 2 coil latching series 4 Form C are for
intermittent operation only. Power should
be applied to coils continuously for no
more than two minutes.
See page 30 for general cautions to be
observed regarding latching relays.
5. While NC relays can be used with any
transmission-wave current to their
operation, due to slight weakening of the
force of magnetic attraction, decreased
resistance to vibration and shock should
be taken into account.
6. The current that energizes the coil in
an NC relay is AC type. Because the AC
sine waveform is distorted, when testing,
it is essential to use a measuring device
that can properly characterize the
distorted waveform.
The operating power of the coil in the 100
V AC 4 Form C type is relatively higher
than other NC types of AC relay and
consequently, the total current applied
through all the contacts should be kept
below 10 A.
7. The AC type NC relay has a special
magnetic design. As a result, once the aside contacts have switched, the b-side
contacts may once again go into a
temporary ON state depending on the
coil inrush phase. To ensure that this
phenomenon does not occur, it is
necessary to carry out sufficient practical
testing with relays installed in actual
devices.

8. When designing top and bottom view
schematic diagrams, note that:
1) “Top view” wiring diagram is indicated
for the flat series because terminals can
be seen from above.
2) “Bottom view” schematic diagram is
indicated for the vertical series because
terminals cannot be seen from above.

9. Cautions for close proximity mounting
When using slim series in close proximity,
mount all relays facing the same
direction. Different mounting directions
may cause change in the relay
characteristics because NC relays are
polarized.

• Socket
1) The vertical (slim) type with solder
terminals has a retainer, which enables
snap-in fixing on chassis, panels, and
similar locations. Because the sockets for
both solder terminals and PC boards
firmly fix the relay at the time of insertion,
once snapped in, spring clips are
unnecessary.
2) For the flat type, pull up the hinged
clasps in the direction of the arrows
shown in the drawing after inserting the
relay. Spring clips are unnecessary.
