1. High contact reliability over a long
life has been made possible for low
level loads.
Using a low level load (1 mV 10µA to 10 V
10 mA) 107 operations were achieved with
a static contact resistance of Max. 100
mΩ (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 magnetic circuit "seesaw balance armature
mechanism", a rated power consumption
of 50 mW (for 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 µV or
less.

NOTES
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
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 {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
,
1. Coil operating power
1) As a general rule, only a pure DC power 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 fluctuate depending on the ambient temperature 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 malfunction.
3. External magnetic field
Since SX relays are highly sensitive polarized relays, their characteristics will be affected 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 ultrasonic cleaning which subject the relay
to high frequency vibrations. It may cause
the contacts to stick.
lt is recommended that a fluorinated hydrocarbon or other alcoholic solvent be
used.
