■Recommended Soldering Method
Temperature indicates the surface temperature of the PCBs.
IRS Method (for surface mounting terminal models)
(1) IRS Method (Mounting Solder: Lead) (2) IRS Method (Mounting Solder: Lead-free)
•The thickness of cream solder to be applied should be within a range between 150 and 200 μm on OMRON’s recommended PCB pattern.
•In order to perform correct soldering, it is recommended that the correct soldering conditions be maintained as shown below on the left side.
Visually check that the Relay is properly soldered.
Precautions
■Correct Use
Handling
Do not unpack the relay until mounting it.
Soldering
Solder: JIS Z3282, H63A or equivalent
Soldering temperature: Approx. 250°C (260°C if the DWS method is
used)
Soldering time: Approx. 5 s max. (approx. 2 s for the first time and
approx. 3 s for the second time if the DWS method is used)
Be sure to make a molten solder level adjustment so that the solder
will not overflow on the PCB.
Claw Securing Force During Automatic
Mounting
During automatic insertion of Relays, make sure to set the securing
force of each claw to the following so that the Relays characteristics
will be maintained.
Environmental Conditions During Operation,
Storage, and Transportation
It is best to keep the relay in its packaging in a controlled environ-
ment until it is ready for mounting.
If the Relay is stored for a long time in an adverse environment with
high temperature, high humidity, organic gases, or sulfide gases, sul-
fide or oxide films will form on the contact surfaces. These films may
result in unstable contact, contact problems, or functional problems.
Therefore, operate, store, or transport the product under specified
environmental conditions.
Latching Relay Mounting
Make sure that the vibration or shock that is generated from other
devices, such as relays in operation, on the same panel and imposed
on the Latching Relay does not exceed the rated value, otherwise the
Latching Relay that has been set may be reset or vice versa. The
Latching Relay is reset before shipping. If excessive vibration or
shock is imposed, however, the Latching Relay may be set acciden-
tally. Be sure to apply a reset signal before use.
Maximum Allowable Voltage
The maximum allowable voltage of the coil can be obtained from the
coil temperature increase and the heat-resisting temperature of coil
insulating sheath material. (Exceeding the heat-resisting tempera-
ture may result in burning or short-circuiting.) The maximum allow-
able voltage also involves important restrictions which include the
following:

•Must not cause thermal changes in or deterioration of the insulating
material.
•Must not cause damage to other control devices.
•Must not cause any harmful effect on people.
•Must not cause fire.
Therefore, be sure to use the maximum allowable voltage as speci-
fied in the catalog.
As a rule, the rated voltage must be applied to the coil. A voltage
exceeding the rated value, however, can be applied to the coil pro-
vided that the voltage is less than or equal to the maximum allowable
voltage. It must be noted that continuous voltage application to the
coil will cause a coil temperature increase which may affect charac-
teristics such as electrical life and coil insulation.
Coating
The Relay mounting on the PCB may be coated or washed but do not
apply silicone coating or detergent containing silicone, otherwise the
silicone coating or detergent may remain on the surface of the Relay.
PCB Mounting
If two or more Relays are closely mounted with the long sides of the
Relays facing each other and soldering is performed with infrared
radiation, the solder may not be properly exposed to the infrared
rays. Be sure to keep the proper distance between adjacent Relays
as shown below to insure formation of good solder joints.
Two or more Relays may be mounted as closely as desired with the
short sides of the Relays facing each other.
