GUIDELINES FOR USAGE
■ For cautions for use, please read " GUIDELINES FOR RELAY USAGE ".
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
■ Cautions for usage of DW relays
● Set and reset pulse time
Regarding the set and reset pulse time of the latching
type, for the purpose of reliable operation under ambient
temperature fluctuations and different operating
conditions, we recommend setting the coil applied set
and reset pulse time to 30 ms or more at the rated coil
voltage.
● Solder and cleaning conditions
• IRS heat conditions ( recommended conditions; number
of reflows: 1 time, measurement location: surface of PC
board where relay is installed )

Cautions to observe when mounting temperature
increases in the relay are greatly dependent on the way
different parts are located a PC board and the heating
method of the reflow device. Therefore, please conduct
testing on the actual device beforehand after making
sure the parts soldered on the relay terminals and
the top of the relay case are within the temperature
conditions given above.

the set coil and reset coil at the same time.
For circuits such as these, please use a magnetic-hold type
latching relay. If you need to use a single stable relay, use
a sealed type relay that is not easily affected by ambient
conditions and make a failsafe circuit design that considers
the possibility of contact failure or disconnection.
■ Maximum allowable voltage and temperature
rise
■ DC Coil operating power
Steady state DC current should be applied to the coil. The
wave form should be rectangular. If it includes ripple, the
ripple factor should be less than 5 %.
However, please check with the actual circuit since the
electrical characteristics may vary. The rated coil voltage
should be applied to the coil and the set/reset pulse time of
latching type relay differs for each relays, please refer to the
relay's individual specifications.
Proper usage requires that the rated coil voltage be
impressed on the coil. Note, however, that if a voltage
greater than or equal to the maximum continuous voltage
is impressed on the coil, the coil may burn or its layers short
due to the temperature rise. Furthermore, do not exceed the
usable ambient temperature range listed in the catalog.
● Operate voltage change due to coil temperature rise
In DC relays, after continuous passage of current in
the coil, if the current is turned OFF, then immediately
turned ON again, due to the temperature rise in the
coil, the operate voltage will become somewhat
higher. Also, it will be the same as using it in a higher
temperature atmosphere. The resistance/temperature
relationship for copper wire is about 0.4 % for 1 ℃,
and with this ratio the coil resistance increases. That
is, in order to operate of the relay, it is necessary that
the voltage be higher than the operate voltage and the
operate voltage rises in accordance with the increase
in the resistance value. However, for some polarized
relays, this rate of change is considerably smaller.

●Low temperature and low humidity
The plastic becomes brittle if the relay is exposed to a
low temperature, low humidity environment for long
periods of time.
●High temperature and high humidity
Storage for extended periods of time ( including
transportation periods ) at high temperature or high
humidity levels or in atmospheres with organic gases
or sulfide gases may cause a sulfide film or oxide film
to form on the surfaces of the contacts and/or it may
interfere with the functions. Check out the atmosphere

●Dew condensation
Condensation occurs when the ambient temperature
drops suddenly from a high temperature and humidity,
or the relay is suddenly transferred from a low ambient
temperature to a high temperature and humidity.
Condensation causes the failures like insulation
deterioration, wire disconnection and rust etc.
Panasonic Industry Co., Ltd. does not guarantee the
failures caused by condensation.
The heat conduction by the equipment may accelerate
the cooling of device itself, and the condensation may
occur.
Please conduct product evaluations in the worst
condition of the actual usage. ( Special attention should
be paid when high temperature heating parts are close
to the device. Also please consider the condensation
may occur inside of the device. )
When a source of silicone substances ( silicone rubber,
silicone oil, silicone coating materials and silicone filling
materials etc. ) is used around the relay, the silicone gas
( low molecular siloxane etc. ) may be produced.
This silicone gas may penetrate into the inside of the
relay. When the relay is kept and used in this condition,
silicone compound may adhere to the relay contacts
which may cause the contact failure. Do not use any
sources of silicone gas around the relay ( Including
plastic sealed types ).
●NOx Generation
When relay is used in an atmosphere high in humidity
to switch a load which easily produces an arc, the NOx
created by the arc and the water absorbed from outside
the relay combine to produce nitric acid.
This corrodes the internal metal parts and adversely
affects operation.
Avoid use at an ambient humidity of 85 % RH or higher
( at 20 ℃ ). If use at high humidity is unavoidable,
please contact our sales representative.
