NOTES
For Cautions for Use, see Relay Technical Information.
■ Usage, transport and storage
conditions
1) Temperature:
–40 to +85C –40 to +185F
2) Humidity: 5 to 85% RH
(Avoid freezing and condensation.)
The humidity range varies with the
temperature. Use within the range
indicated in the graph below.
3) Atmospheric pressure: 86 to 106 kPa
Temperature and humidity range for
usage, transport, and storage
4) Condensation
Condensation forms when there is a
sudden change in temperature under
high temperature and high humidity
conditions. Condensation will cause
deterioration of the relay insulation.
5) Freezing
Condensation or other moisture may
freeze on the relay when the
temperatures is lower than 0C 32F.
This causes problems such as sticking of
movable parts or operational time lags.
6) Low temperature, low humidity
environments
The plastic becomes brittle if the relay is
exposed to a low temperature, low
humidity environment for long periods of
time.
■ Solder and cleaning conditions
1) Please obey the following conditions
when soldering automatically.
(1) Preheating: Within 120C 248F
(solder surface terminal portion) and
within 120 seconds
(2) Soldering iron: 260C5C
500F41F (solder temperature) and
within 6 seconds (soldering time)
2) Do not use ultrasonic cleaning.
This will adversely affect the relay
characteristics. Also, it is recommended
that alcoholic solvents be used.
■ Certification
1) This relay is UL and C-UL certified.
UL and C-UL standards:
5 A 277 V AC 70C
5 A 30 V DC
2) This relay is certified by VDE.
VDE standards:
5 A 250 V AC cos = 1.0 70C
5 A 30 V DC 0ms
3) UL, C-UL and VDE certified ratings are
displayed on the packaging box.
(On the relay, only the certification marks
are shown and not the certified ratings.
Please refer to the product specification
diagrams to see what is stamped.)
■ Part number display
The “W” at the end of the part number
only appears on the inner and outer
packaging. It does not appear on the
relay itself.
■ Others
1) To ensure good operation, please
keep the voltage on the coil ends to 5%
(at 20C 68F) of the rated coil operation
voltage. Also, please be aware that the
pick-up voltage and drop-out voltage may
change depending on the temperature
and conditions of use.
2) Keep the ripple rate of the nominal coil
voltage below 5%.
3) The cycle lifetime is defined under the
standard test condition specified in the
JIS C 5442 standard (temperature 15 to
35C 59 to 95F, humidity 25 to
75%R.H.). Check this with the real device
as it is affected by coil driving circuit, load
type, activation frequency, activation
phase, ambient conditions and other
factors.
Also, be especially careful of loads such
as those listed below.
(1) When used for AC load-operating and
the operating phase is synchronous.
Rocking and fusing can easily occur due
to contact shifting.
(2) Highly frequent load-operating
When highly frequent opening and
closing of the relay is performed with a
load that causes arcs at the contacts,
nitrogen and oxygen in the air is fused by
the arc energy and HNO3 is formed. This
can corrode metal materials.
Three countermeasures for these are
listed here.
• Incorporate an arc-extinguishing circuit.
• Lower the operating frequency
• Lower the ambient humidity
4) Minimum switching capacity is a
guideline as to the lowest possible level
at which it will be possible for a low level
load to allow switching. This value can
change due to the switching frequency,
environmental conditions, and desired
reliability level, therefore it is
recommended to check this with the
actual load.
5) Heat, smoke, and even a fire may
occur if the relay is used in conditions
outside of the allowable ranges for the
coil ratings, contact ratings, operating
cycle lifetime, and other specifications.
Therefore, do not use the relay if these
ratings are exceeded.
6) If the relay has been dropped, the
appearance and characteristics should
always be checked before use.
7) Incorrect wiring may cause
unexpected events or the generation of
heat or flames.
8) Creepage distance and clearances
between contact and coil: Min. 6 mm
