■ Other things to observe
• Exceeding
the stipulated conditions when soldering may
affect coaxial switch performance. Be sure to consult us
beforehand.
• Creep-up,
wettability and solder strength will differ
depending on changes in the mounting conditions and
type of solder. Please evaluate based on actual production
conditions.
• Only
apply coating after the relay has returned to room
temperature.
• Since
thermal stress on a relay will depend on the PC
board and process conditions, please be sure to test using
the actual PC board.

A
fluctuations and different operating conditions, we
recommend setting the coil applied set and reset pulse
time to 10 ms or more at the rated coil voltage.
• The relay is shipped in the reset position. But jolts
during transport or impacts during installation can
change the reset position. It is, therefore, advisable to
build a circuit in which the relay can be initialized ( set
and reset ) just after turning on the power.
Please chuck the

portion.
Avoid chucking the center of the
relay. In addition, excessive
chucking pressure to the pinpoint of
the relay should be also avoided.
● Precaution
Table 1: Chucking pressure
When using at 3.5 A, connection of NO ( pin #5 and #8 )

GUIDELINES FOR SIGNAL RELAYS USAGE
■ For cautions for use, please read ” GUIDELINES FOR RELAY USAGE “.
PRECAUTIONS FOR COIL INPUT
■ Long term current carrying
■
Coil connection
A circuit that will be carrying a current continuously for
long periods without relay switching operation. ( circuits for
emergency lamps, alarm devices and error inspection that,
for example, revert only during malfunction and output
warnings with form B contacts )
When connecting coils of polarized relays, please check coil
polarity ( ＋, － ) at the internal connection diagram
( Schematic ).
If any wrong connection is made, it may cause unexpected
malfunction, like abnormal heat, fire and so on, and circuit
do not work.
Avoid impressing voltages to the set coil and reset coil at the
same time.
Continuous,long-term current to the coil will facilitate
deterioration of coil insulation and characteristics due to
heating of the coil itself. 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
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.
■
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.
● Operate voltage change due to coil temperature rise
( hot start )
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.
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.

GUIDELINES FOR SIGNAL RELAYS USAGE
NOTES
■
Usage, Storage, and Transport Conditions
During usage, storage, or transportation, avoid locations
subject to direct sunlight and maintain normal temperature,
humidity, and pressure conditions.
The allowable specifications for environments suitable for
usage, storage, and transportation are given below.
1) Temperature:
● Condensation
Condensation occurs when the ambient temperature
drops suddenly from a high temperature and humidity,
or the relay and microwave device is suddenly transferred
from a low ambient temperature to a high temperature
and humidity.
The allowable temperature range differs for each relay,
so refer to the relay’s individual specifications.
In addition, when transporting or storing relays while
they are tube packaged, there are cases when the
temperature may differ from the allowable range.
In this situation, be sure to consult the individual
specifications.
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.
2) Humidity: 5 to 85% RH
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. )
The humidity range varies with the temperature.
Use within the range indicated in the graph.
( The allowable temperature depends on the relays. )
Humidity (％ RH)
● Icing
Condensation or other moisture may freeze on relays
when the temperature become lower than 0 ℃.
This icing causes the sticking of movable portion, the
operation delay and the contact conduction failure etc.
Panasonic Industry Co., Ltd. does not guarantee the
failures caused by the icing.
The heat conduction by the equipment may accelerate
the cooling of relay itself and the icing may occur.
Please conduct product evaluations in the worst condition
of the actual usage.

● Low temperature and low humidity
The plastic becomes brittle if the switch 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 in which the units are to be
stored and transported.
● Package
In terms of the packing format used, make every effort
to keep the effects of moisture, organic gases and sulfide
gases to the absolute minimum.

GUIDELINES FOR SIGNAL RELAYS USAGE
● Storage requirements
Since the surface-mount terminal type is sensitive to
humidity it is packaged with tightly sealed anti-humidity
packaging. However, when storing, please be careful of
the following.
4 ) The following cautionary label is affixed to the anti-
humidity pack.
1) Please use promptly once the anti-humidity pack is
opened. ( within 72 hours, Max. 30 ℃ / 70% RH ).
If left with the pack open, the relay will absorb
moisture which will cause thermal stress when reflow
mounting and thus cause the case to expand. As a
result, the seal may break.
2) If relays will not be used within 72 hours, please store
relays in a humidity controlled desiccator or in an anti-
humidity bag to which silica gel has been added.
* If the relay is to be soldered after it has been exposed to excessive
humidity atmosphere, cracks and leaks can occur.
Be sure to mount the relay under the required mounting conditions.
3) When relays ( which is packaged with humidity
indicator and silica gel ) meeting one of below criteria,
please bake ( dry ) before use.
• When the storage conditions specified in 1) are
exceeded.
● Silicon
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.
• When humidity indicator is in Ⅲ or Ⅳ status according
to judgement standard.
<How to judge>
Please check humidity indicator color and decide if
baking is necessary or not.
Do not use any sources of silicone gas around the relay
( Including plastic seal types ).
●: indicate brown, ○: Other than brown ( blueish color )
Bake treatment
● NOx Generation
5％
10％
60％
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.

■ Cleaning
• Although
the environmentally sealed type relay (plastic
sealed type,etc. ) can be cleaned, avoid immersing
the relay into cold liquid ( such as cleaning solvent )
immediately after soldering.
• Cleaning
with the boiling method is recommended ( The
temperature of cleaning liquid should be 40℃ or lower ).
Avoid ultrasonic cleaning on relays.
Use of ultrasonic cleaning may cause breaks in the coil
or slight sticking of the contacts due to the ultrasonic
energy.
Doing so may deteriorate the sealing performance.
•
Surface-mount terminal type relay is sealed type and it
can be cleaned by immersion.
Use pure water or alcohol-based cleaning solvent.
Please refer to
