from the allowable range. In this case be sure to check the
individual specifications.
Also allowable humidity level is influenced by temperature,

GUIDELINES FOR SIGNAL RELAYS USAGE
For cautions for use, please read “GUIDELINES FOR RELAY USAGE”.
https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp
Precautions for Coil Input
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 affected by ambient conditions and make a failsafe
circuit design that considers the possibility of contact failure or
disconnection.
Temperature rise due to pulse voltage
When a pulse voltage with ON time of less than 2 minutes is used, the
coil temperature rise bares no relationship to the ON time. This varies
with the ratio of ON time to OFF time, and compared with continuous
current passage, it is rather small. The various relays are essentially
the same in this respect.
Current passage time
(%)
For continuousu passage
Tempereture rise value is 100%
ON : OFF = 3 : 1
About 80%
ON : OFF = 1 : 1
About 50%
ON : OFF = 1 : 3
About 35%
DC Coil operating power
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, fire 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.
Maximum allowable voltage for coil
In addition to being a requirement for relay operation stability, the
maximum continuous impressed coil voltage is an important constraint
for the prevention of such problems as thermal deterioration or
deformity of the insulation material, or the occurrence of fire hazards.
Panasonic Corporation Electromechanical Control Business Division
industrial.panasonic.com/ac/e/
ON : OFF = 1 : 1
Voltage
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.
Time
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.

GUIDELINES FOR SIGNAL RELAYS USAGE
Ambient Environment
Dew 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. 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 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.
Storage requirements
Since the SMD type is sensitive to humidity it is packaged with tightly
sealed anti-humidity packaging. However, when storing, please be
careful of the following.
1) Please use promptly once the anti-humidity pack is opened.(Signal
relay: within 72 hours, Max. 30°C/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) The following cautionary label is affixed to the anti-humidity pack.
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. 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 affects 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

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) Surface mount terminal type relay is sealed type and it can be
cleaned by immersion. Use pure water or alcohol-based cleaning
solvent.
3) 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 the
ultrasonic energy.
Please refer to "the latest product specifications"
when designing your product.
