tween contacts of different polarity with an insertion loss of 0.2 dB max.
• Miniaturized to 10.3 × 6.9 × 5.4 mm (L × W × H).
• Rated power consumption of 100 mW with high sensitivity
• Single-side stable and single-winding latching models are available.
• Models with a smaller footprint (G6K(U)-2F-RF-S) are available to help save space.
• G6K(U)-2F-RF-T models for 3-GHz band join the lineup with a downsized footprint.
• New PCB terminals models are available.
■Model Number Legend ■Application Examples
• Communications equipment

Standard Specifications
Board space-saving model
Compatible with 3 GHz
PCB terminals
Note 1. When ordering, add the rated coil voltage to the model number.
Example: G6K-2F-RF DC3
However, the notation of the coil voltage on the product case as well as on the packing will be marked as @@ VDC.
Note 2. When ordering Relays in tape packing, add "-TR03" to the end of the model number.
Example: G6K-2F-RF-TR03 DC3
Relays per reel: 300 pcs for -TR03
Be sure since "-TR" is not part of the relay model number, it is not marked on the relay case.
When ordering tape packing, minimum order unit is 1 reel (300 pcs ✕ 1 = 300 pcs).
Note 3. Surface mounting terminal (SMT) standard models are shipped in moisture-proof package.
PCB terminal standard types do not require moisture proof packaging and therefore shipped in non-moisture-proof package.

■Tube Packing and Tape Packing Specifications
Surface mounting terminal (SMT) standard models are shipped in moisture-proof package, and PCB terminal standard types do not
require moisture proof packaging and therefore shipped in non-moisture-proof package.
Please refer to "Correct Use" for handling after opening moisture-proof packaging for Surface mounting terminal (SMT) models.
(1) Tube Packing
• G6K-2P-RF in tube packing are arranged so that the
orientation mark of each Relay in on the left side. Fifty Relays
are packed on one tube.
Be sure not to make mistakes in Relay orientation when
mounting the Relay to the PCB.
Tube length: 520 mm (stopper not included)
No. of Relays per tube: 30 pcs
(2) Tape Packing (Surface Mounting Terminal Models)
• Add “TR03” to the end of the model number to order Relays in
tape packing.
If “-TR03” is not added, the Relays will be provided in tray
packing.
Relays per reel: 300 pcs

■G6K(U)-2F-RF(-S, -T) Recommended Soldering Method
●Recommended Conditions for IRS Method (Surface-mounting Terminals)
(1) IRS Method (Mounting Solder: Lead)
(2) IRS Method (Mounting Solder: Lead-free)
• The thickness of cream solder to be applied should be
between 200 and 250 m and the land pattern should be
based on OMRON’s recommended PCB pattern.
• To maintain the correct soldering joint shown in the following
diagram, we recommend applying solder with the soldering
conditions shown on the left.
Check the soldering in the actual mounting conditions before use.

■Safety Precautions
●For general precautions on PCB Relays, refer to the precautions provided in General Information of the Relay Product
Data Book.
●Relay Handling
• Use the Relay as soon as possible after opening the
moistureproof package. (As a guideline, use the Relay within
one week at 30°C or less and 60% RH or less.) 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
seal 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.
●Environmental Conditions for Usage, Storage, and
Transport
• Avoid direct sunlight when using, storing, or transporting the
Relay and maintain normal temperature, humidity, and
pressure conditions.
●Long-term, Continuous ON Contacts
• Using the Relay in a circuit where the Relay will be ON continuously
for long periods (rather than switching) can lead to unstable contacts
because the heat generated by the coil itself will affect the insulation
and can cause 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 adding fail-safe circuits in case the contact
fails or the coil burns out.
●Claw Securing Force During Automatic Mounting
• During automatic insertion of Relays, be sure to set the
securing force of each claw to the following so that the Relay’s
characteristics will be maintained.
Secure the claws to the shaded area. Do not attach them to the center of
the Relay or just one part of the Relay.
●Coating
• Do not use silicone coating to coat the Relay when it is
mounted to the PCB. Do not wash the PCB after the Relay is
mounted using detergent containing silicone. Otherwise, the
detergent may remain on the surface of the Relay.
●Repeatability
• Contact your OMRON representative if the Relay will be used
in an application that requires high repeatability in
high-frequency characteristics for the microload region. (Such
applications include testing and measurement equipment and
ATE applications.)
●About use of an IC socket.
For: G6K-2P-RF
• When using IC sockets, select IC sockets by confirming that
the sockets Rated/Spec./Characteristics are within the range
of using condition.
Also, confirm whether there is any problem of electric
capability or plug insertion or not with actual using condition.
●Others
For: G6K-2P-RF
• The dotted line below on the surface of relay is connected with
a metal case (ground).
So confirm the actual influence of insulation and signal
characteristics when designing.
