Temperatures indicate the surface temperatures of the PCB.
IRS Method (for surface-mounting terminal models)
• 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.

Surface-Mounting Signal Relay – G6K
Precautions
CORRECT USE
Handling
Leave the Relay unpacked until mounting it.
Soldering
Solder: JIS Z3282, H63A
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 are maintained.
Environmental Conditions During Operation, Storage, and
Transportation
Protect the Relay from direct sunlight and keep the Relay under
normal temperature, humidity, and pressure.
If the Relay is stored for a long time in an adverse environment
with high temperature, high humidity, organic gases, or sulphide
gases, sulphide 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 accidentally. 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
temperature may result in burning or short-circuiting.) The
maximum allowable 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 beyond
the value specified 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
provided that the voltage is less than the maximum allowable
voltage. It must be noted that continuous voltage application to
the coil will cause a coil temperature increase thus affecting
characteristics such as electrical life and resulting in the
deterioration of coil insulation.
Coating
The Relay mounted 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.
Two or more Relays may be closely mounted with the short sides
of the Relays facing each other.
