2. Specifications (relay)
Notes: *1. 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.
*2. Response time is the time after the coil voltage turns off until the time when “a” contact turns off.
*3. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*4. Response time of built-in diode type is 12 ms or less (excluding contact bounce time when nominal coil voltage is applied to the coil).

NOTES
1. For cautions for use, please read “GENERAL
APPLICATION GUIDELINES”.
2. Coil operating power
Pure DC current should be applied to the coil. If it includes
ripple, the ripple factor should be less than 5%. However, check
it with the actual circuit since the characteristics may be slightly
different.
The wave form should be rectangular.
3. Coil connection
When connecting coils, refer to the wiring diagram to prevent
mis-operation or malfunction.
4. Cleaning
This relay is not sealed, therefore, immersion may cause failure.
Be careful that flux does not overflow onto the PC board or
penetrate inside the relay.
5. Soldering
When using automatic soldering, the following conditions are
recommended
1) Preheating: 120°C 248°F, within 120 Sec (PC board solder
surface)
2) Soldering: 260°C±5°C 500°F±41°F, within 6 Sec
6. Other
1) If the relay has been dropped, the appearance and
characteristics should always be checked before use.
2) The switching lifetime is defined under the standard test
condition specified in the JIS* C 5442-1996 standard
(temperature 15 to 35°C 59 to 95°F, humidity 25 to 75%). Check
this with the actual product as it is affected by the coil driving
circuit, load type, activation frequency, activation phase, ambient
conditions and other factors.
Also, be especially careful with loads such as those listed below.
(1) When used for AC load-operation and the operating phase is
synchronous. Rocking and fusing can easily occur due to
contact shifting.
(2) During high frequency on/off operation with certain loads,
arcing may occur at the contacts. This can cause fusion to
Oxygen and Nitrogen gas in the air creating Nitric Acid (HNO3)
which can cause corrosion to the contacts.
Please see the following countermeasure examples:
1. Incorporate an arc-extinguishing circuit.
2. Lower the operating frequency
3. Lower the ambient humidity
3) For secure operations, nominal coil voltage should be applied.
In addition, please note that pick-up and drop-out voltage will
vary according to the ambient temperature and operating
conditions.
4) Heat, smoke, and/or fire may occur if the relay is used outside
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. Also, make sure
that the relay is wired correctly.
5) Incorrect wiring may cause false operation or generate heat or
flames.
6) Check the ambient conditions when storing or transporting
the relays and devices containing the relays. Freezing or
condensation may occur in the relay causing damage. Avoid
exposing the relays to heavy loads, or strong shock and
vibration.
7. Usage, transport and storage conditions
1) Ambient temperature, humidity, and atmospheric pressure
during usage, transport, and storage of the relay:
(1) Temperature: –40 to +85°C –40 to +185°F
(When the temperature is 70 to 85°C 158 to 185°F, reduce the 6
A max. switching current by 0.1 A/°C.)
(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
2) 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.
3) Freezing
Condensation or other moisture may freeze on the relay when
the temperatures is lower than 0°C 32°F. This causes problems
such as sticking of movable parts or operational time lags.
4) Low temperature and low humidity
At low temperature, low humidity environments, the plastic
becomes brittle.
Please note corrections.
8. Please connect DC coil types with LED and built-in diode
correctly by verifying the coil polarity (“+” and “–”).
Connecting with reverse polarity will cause the LED not to
light and damage the built-in diode due to its specification.

GUIDELINES FOR POWER, HIGH-CAPACITY DC CUT OFF AND SAFETY RELAYS USAGE
Precautions for Coil Input
For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
Ambient Environment
Long term current carrying
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) 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 a󰀨ected by ambient conditions and make a failsafe
circuit design that considers the possibility of contact failure or
disconnection.
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 di󰀨ers for
each relays, please refer to the relay's individual specications.
Coil connection
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, re and so on, and circuit do not work. Avoid
impressing voltages to the set coil and reset coil at the same time.
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.
Operate voltage change due to coil temperature rise
(Hot start)
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 pick-up 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°C, 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 pick-up voltage and the pick-up voltage rises in
accordance with the increase in the resistance value. However, for
some polarized relays, this rate of change is considerably smaller.
●Usage, Transport, and Storage Conditions
During usage, storage, or transportation, avoid locations subjected to
direct sunlight and maintain normal temperature, humidity and
pressure conditions.
●Temperature/Humidity/Pressure
When transporting or storing relays while they are tube packaged,
there are cases the temperature may di󰀨er from the allowable range.
In this case be sure to check the individual specications.
Also allowable humidity level is inuenced by temperature, please
check charts shown below and use relays within mentioned conditions.
(Allowable temperature values di󰀨er for each relays, please refer to
the relay's individual specications.)
1) Temperature:
The tolerance temperature range di󰀨ers for each relays, please
refer to the relay’s individual specications

●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 Corporation 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.)
●Icing
Condensation or other moisture may freeze on relays when the
temperature become lower than 0°C.This icing causes the sticking of
movable portion, the operation delay and the contact conduction failure
etc. Panasonic Corporation 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 sulde gases may cause a sulde lm or oxide lm 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.

Others
Please refer to "the latest product specications"
when designing your product.
•Requests to customers:
https://industrial.panasonic.com/ac/e/salespolicies/
●Package
In terms of the packing format used, make every e󰀨ort to keep the
e󰀨ects of moisture, organic gases and sulde gases to the absolute
minimum.
●Silicon
When a source of silicone substances (silicone rubber, silicone oil,
silicone coating materials and silicone lling 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 seal
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 a󰀨ects operation.
Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use
at high humidity is unavoidable, please contact our sales
representative.
Cleaning
1) 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. Doing so may
deteriorate the sealing performance.
2) Cleaning with the boiling method is recommended(The temperature
of cleaning liquid should be 40°C 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
ultrasonic energy.
