FEATURES
1. High contact reliability over a long
life has been made possible for low
level loads.
Using a low le vel load (1 mV 10
µ
A to 10 V
10 mA) 10
7
operations were achieved with
a static contact resistance of Max. 100
m
Ω
(voltage drop of 20 mV, 1 mA, 1 kHz)
and a dynamic contact resistance of Max.
1
Ω
(Measurement delay 10 ms, voltage
drop of 20 mV, 1 mA, 1 kHz).
2. High sensitibity of 50 mW
By using the highly efficient polar magnet-
ic circuit "seesaw balance armature
mechanism", a rated pow er consumption
of 50 mW (f or single side stable type) has
been achieved.
3. Low thermal electromotive force
Reducing the heat from the coil enables a
thermal electromotive force of 3
µ
V or
less.

NOTES
1. Coil operating power
1) As a general rule, only a pure DC pow-
er supply should be used f or the coil driv e.
2) T o 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 aw are that the
pick-up and drop-out voltages will fluctu-
ate depending on the ambient tempera-
ture and operating conditions.
3) The ripple factor f or the voltage applied
to the coil should be less than 5%.
4) For set and reset latching relays, the
rated operating v oltage should be applied
to the coil for 10 ms or more.
2. Coil connection
When connecting coils, ref er to the wiring
diagram to prevent mis-operation or mal-
function.
3. External magnetic field
Since SX relays are highly sensitive polar-
ized rela ys , their char acteristics will be af-
f ected by a strong external magnetic field.
A void using the rela y under that condition.
4. Cleaning
In automatic cleaning, cleaning with the
boiling method is recommended. A v oid ul-
trasonic cleaning which subject the relay
to high frequency vibrations. It ma y 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.
2) Tape and reel packing
(1) Tape dimensions mm inch
(2) Dimensions of plastic reel mm inch
6. Automatic insertion
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.
Avoid chucking the center of the relay.
In addition, excessive chucking pressure
to the pinpoint of the rela y should be also
avoided.
