Surface Mounting Relay
Surface Mounting Relay with the World’s
Smallest Mounting Area
• Subminiature model as small as 5.2 (H) × 6.5 (W) × 10 (L) mm is ideal for
high-density mounting (G6K(U)-2F(-Y)).
• Low profile of 5.2 mm improves mounting efficiency (G6K(U)-2F(-Y)).
• Light weight of 0.7 g contributes to higher speed mounting.
• Consumes approximately 70% the power of a conventional OMRON model and
operates at a current that is as low as 100 mW.
• Surface mounting terminal models incorporate a unique terminal structure with
high infrared irradiation efficiency which allows the terminal temperature to rise
easily when mounting the IRS, thus ensuring excellent soldering.
• Ensures a dielectric strength of 1,500 VAC and conforms to FCC Part 68 (i.e., withstanding an impulse withstand voltage of
1,500 V for 10 × 160 μs).
• -Y models offer an impulse withstand voltage of 2,500 V for 2 × 10 μs (conforms to Telcordia specifications) by optimizing the
distance between coil and contacts.
• Standard model conforms to UL/CSA standards.
RoHS Compliant

■Recommended Soldering Method
●IRS Method (for Surface-mounting Terminal Relays)
Temperature (°C)
(1) IRS Method (Mounting Solder: Lead)
Soldering
220 to 245
• 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.

■Precautions
●Please refer to “PCB Relays Common Precautions” for correct use.
Correct Use
●Long-term Continuously ON Contacts
G
6
K
• Using the Relay in a circuit where the Relay will be ON
continuously for long periods (without switching) can lead to
unstable contacts because the heat generated by the coil itself
will affect the insulation, causing a film to develop on the
contact surfaces. We recommend using a latching relay
(magnetic-holding relay) in this kind of circuit. If a single-side
stable model must be used in this kind of circuit, we
recommend using a fail-safe circuit design that provides
protection against contact failure or coil burnout.
●Relay Handling
• Use the Relay as soon as possible after opening the
moistureproof package. If the Relay is left for a long time after
opening the moisture-proof package, the appearance may
suffer and seal failure may occur after the solder mounting
process. To store the Relay after opening the moisture-proof
package, place it into the original package and sealed the
package with adhesive tape.
• When washing the product after soldering the Relay to a PCB,
use a water-based solvent or alcohol-based solvent, and keep
the solvent temperature to less than 40°C. Do not put the
Relay in a cold cleaning bath immediately after soldering.
●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.
• 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.

●Environmental Conditions During Operation, Storage,
and Transportation
• 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.
G6K-2G
• Protect the Relay from direct sunlight and keep the Relay
under normal temperature, humidity, and pressure.
●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.
