NOTES
1. Coil operating power
1) As a general rule, only a pure DC pow-
er supply should be used for the coil drive.
2) To ensure proper operation, the voltage
applied to both terminals of the coil should
be
±5%
(at 20°C
68°F)
the rated operating
voltage of the coil. Also, be aware that the
pick-up and drop-out voltages will fluctu-
ate depending on the ambient tempera-
ture and operating conditions.
3) The ripple factor for the voltage applied
to the coil should be less than 5%.
4) For set and reset latching relays, the
rated operating voltage should be applied
to the coil for 10 ms or more.
2. Coil connection
When connecting coils, refer to the wiring
diagram to prevent mis-operation or mal-
function.
3. External magnetic field
Since GN relays are highly sensitive po-
larized relays, their characteristics will be
affected by a strong external magnetic
field. Avoid using the relay under that con-
ditions.
4. Cleaning
In automatic cleaning, cleaning with the
boiling method is recommended. Avoid ul-
trasonic cleaning which subjects the relay
to high frequency vibrations. It may cause
the contacts to stick.
lt is recommended that a fluorinated hy-
drocarbon or other alcoholic solvent be
used.
5. Packing style
1) The relay is packed in a tube with the
relay orientation mark on the left side, as
shown in the figure below.
Orientation (indicates PIN No.1)stripe
Please chuck the
portion.
Avoid chucking the center of the relay.
In addition, excessive chucking pressure
to the pinpoint of the relay should be
avoided.

6. Automatic insertion
To maintain the internal function of the
relay, the chucking pressure should not
exceed the values below.
Chucking pressure in the direction A:
4.9 N {500gf} or less
Chucking pressure in the direction B:
9.8 N {1 kgf} or less
Chucking pressure in the direction C:
9.8 N {1 kgf} or less
