NOTES
1. Coil operating power
5. Packing style
6. Automatic insertion
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.
1) The relay is packed in a tube with the
relay orientation mark on the left side, as
shown in the figure below.
To maintain the internal function of the re-
lay, the chucking pressure should not ex-
ceed the values below.
Chucking pressure in the direction A:
4.9 N {500 gf} 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

Please chuck the
portion.
When connecting coils, refer to the wiring
diagram to prevent mis-operation or mal-
function.

Avoid chucking the center of the relay.
In addition, excessive chucking pressure
to the pinpoint of the relay should be also
avoided.

Since SX relays are highly sensitive polar-
ized relays, their characteristics will be af-
fected by a strong external magnetic field.
Avoid using the relay under that condition.

4. Cleaning
In automatic cleaning, cleaning with the
boiling method is recommended. Avoid ul-
trasonic cleaning which subject 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.
