G6K Surface Mounting Relay
Surface Mounting Relay with the World’s
Smallest Mounting Area and a Height of
Only 5.2 mm
Subminiature model as small as 5.2 (H) x 6.5 (W)
x 10 (L) mm is ideal for high-density mounting.
Low profile of 5.2 mm and weight of only 0.7 g
combine to improve mounting efficiency.
Models with inside-L surface mounting terminals
are available.
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 irradi-
ation efficiency which allows the terminal temper-
ature 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 x
160 µs).
New-Y models offer an impulse withstand voltage
of 2,500 V for 2 x 10 µs (conforms to Telcordia
specifications) by optimizing the distance between
coil and contacts.
Conforms to UL1950 (File No. E41515)/CSA
C22.2 No. 950 (File No. LR24825)
The above specifications are ensured as of August 1999.

2. Values in parentheses are actual values.
3. The insulation resistance was measured with a 500-VDC megohmmeter applied to the same parts as those used for checking
the dielectric strength.

value may vary depending on the switching frequency and operating environment. Always double-check relay suitability under

Recommended Soldering Method
Temperature indicate 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
Refer to page 25 for information on general precautions. Be sure to read these precautions before using the Relay.
Correct Use
Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continu-
ously 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 moisture-
proof package. If the Relay is left for a long time after opening the
moisture-proof package, the appearance may suffer and seal fail-
ure 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.
Soldering
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 adjust the level of the molten solder so that the solder
will not overflow onto the PCB.
Claw Securing Force During Automatic Mounting
During automatic insertion of Relays, make sure to set the secur-
ing force of each claw to the following so that the Relays charac-
teristics will be 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 sulfide
gases, sulfide 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 exces-
sive 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 maxi-
mum allowable voltage also involves important restrictions which
include the following:
Must not cause thermal changes in or deterioration of the insu-
lating 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 volt-
age. It must be noted that continuous voltage application to the
coil will cause a coil temperature increase thus affecting charac-
teristics 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, other-
wise 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 adja-
cent Relays as shown below.
Two or more Relays may be closely mounted with the short sides
of the Relays facing each other.
