GUIDELINES FOR USAGE
or cautions for use, please read “GUIDELINES FOR SIGNAL RELAYS USAGE” and “GUIDELINES FOR RELAY
F
USAGE”.
Cautions for usage of TQ relay
Latching
• Use latching when conditions involve continuous carrying
current.
• Regarding the set and reset pulse time, 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 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.

External magnetic field
Since TQ relays are highly sensitive polarized relays, their
characteristics will be aff ected by a strong external magnetic
field. Avoid using the relay under that condition.

PRECAUTIONS FOR COIL INPUT
Long term current carrying
Maximum allowable voltage and temperature rise
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.
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.
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.
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 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°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 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.
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.

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: 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.
2) Humidity: 5 to 85% RH
The humidity range varies with the temperature.
Use within the range indicated in the graph.
(The allowable temperature depends on the relays.)
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 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.

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 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.)

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.
3) Pressure: 86 to 106 kPa
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.
1) Please use promptly once the anti-humidity pack is opened.
(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.
4) The following cautionary label is affixed to the anti-humidity
pack.
* 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.
When humidity indicator is in Ⅲ or Ⅳ status according to
judgement standard.
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).
Please check humidity indicator color and decide if baking is
necessary or not.

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
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) 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.
