RATING  
Coil data  
• Operating characteristics such as ‘Operate voltage’ and ‘Release voltage’ are influenced by mounting conditions, ambient  
temperature, etc.  
Therefore, please use the relay within ±5% of rated coil voltage.  
• ‘Initial’ means the condition of products at the time of delivery.

GUIDELINES FOR USAGE  
For cautions for use, please read “GUIDELINES FOR REL
A
Y
U
SAGE”.  
Cautions for usage of ST relays  
• The standard values of operate (set) and release (reset)  
voltage are for when the relay is installed with the terminals  
oriented downward.  
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 50 ms or  
more at the rated coil voltage.  
• When using, please be aware that the N.C. and N.O. sides  
of 1 Form A 1 Form B type may go on simultaneously at  
operate time and release time.

Mounting method of relay  
Removing method of relay  
1) Align the direction of relay and  
socket.  
1) When removing the relay, completely  
release the hooks on both sides and  
pull the relay out.

2) In case there is not enough  
space to grasp relay with  
fingers, after completely  
removing both hooks, use  
screwdrivers in the way  
shown.  
2) Insert the relay all the way in, so it is securely in place.  
3) Press the hook section in the direction of the arrow and firmly  
secure the relay with the hook.

3) Exercise care when removing relays. If greater than necessary  
force is applied at the socket hooks, deformation may alter the  
dimensions so that the hook will no longer catch, and other  
damage may also occur.

GUIDELINES FOR POWER, HIGH-CAPACITY DC CUT OFF AND SAFETY RELAYS USAGE  
For cautions for use, please read “GUIDELINES FOR REL
A

SAGE”.  
Precautions for Coil Input  
Long term current carrying  
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.  
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.  
Operate voltage change due to coil temperature rise  
In DC relays, after continuous passage of current in the coil, if the  
current is turned OF
F
,
t
hen 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.  
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.  
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.  
Ambient Environment  
Dew condensation  
Usage, Transport, and Storage Conditions  
During usage, storage, or transportation, avoid locations subjected  
to direct sunlight and maintain normal temperature, humidity and  
pressure conditions.  
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.  
Temperature/Humidity/Pressure  
When transporting or storing relays while they are tube packaged,  
there are cases the temperature may differ from the allowable  
range. In this case be sure to check the individual specifications.  
Also allowable humidity level is influenced by temperature, please  
check charts shown below and use relays within mentioned  
conditions. (Allowable temperature values differ for each relays,  
please refer to the relay’s individual specifications.)  
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  
1)
T
e
mperature:  
The tolerance temperature range differs for each relays, please  
refer to the relay’s individual specifications  
2) Humidity: 5 to 85 % RH  
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.  
3) Pressure: 86 to 106 kPa  
Humidity (% RH)  
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.

Package  
In terms of the packing format used, make every effort to keep the  
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.  
effects of moisture, organic gases and sulfide gases to the absolute  
minimum.  
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 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.  
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).  
Others  
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. Doing so may  
deteriorate the sealing performance.  
• 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.  
Please refer to
“the latest product specifications”  
when designing your product.
