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.
For Cautions for Use, see Relay Technical Information.

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 a-
side 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.
