Low Signal Relay
G6L
Extremely Thin SPST-NO Flat Relay, One
of the Thinnest Relays in the World
• Uses 20% less mounting area and approximately 64% less
volume in comparison with the G5V-1 relay.
• Measures just 7.0 (W) x 10.6 (L) x 4.5 (H) mm for surface-
mount or 4.1 (H) for through-hole.
• High dielectric strength: 1,000 VAC between coil and con-
tacts and 750 VAC between contacts of the same polarity.
• Conforms to FCC Part 68.
• UL recognized / CSA certified
• RoHS Compliant - Use of lead completely eliminated.

Note: 1. When ordering, add the rated coil voltage to the model number.
Example: G6L-1P DC12
2. When ordering tape packing (surface mount versions), add "-TR" to the model number.
Example: G6L-1F-TR DC12
Be sure since "-TR" is not part of the relay model number, it is not marked on the relay case.

■Contact Ratings
Note: This value was measured at a switching frequency of 120 operations/min. This value may vary, depending on switching frequency, operating
conditions, expected reliability level of the relay, etc. It is always recommended to double-check relay suitability under actual load conditions.
■Coil Ratings
Note: 1. The rated current and coil resistance are measured at a coil temperature of 23°C with a tolerance of ±10%.
2. The operating characteristics are measured at a coil temperature of 23°C.
3. The maximum voltage is the highest voltage that can be imposed on the relay coil.
4. The voltage measurements for Pick-up/Dropout are the values obtained for instantaneous changes in the voltage (rectangular wave).
■Characteristics
Note: 1. The contact resistance was measured with 10 mA at 1 VDC with a fall-of-potential method.
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 dielec-
tric strength.
4. The above values are initial values.

•The thickness of cream solder to be applied should be 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

Precautions
Be sure to read the precautions and information common to all Electromechanical Relays, contained in the Technical User’s Guide,
“Electromechanical Relays, Technical Information”, for correct use.
■Correct Use
Long-term Continuously ON Contacts
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. Be sure to use a
fail-safe circuit design that provides protection against contact failure
or coil burnout.
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 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.
Claw Securing Force During Automatic
Insertion
During automatic insertion of Relays, make sure to set the securing
force of the claws to the following values so that the Relay character-
istics will be maintained.
Environmental Conditions During Operation,
Storage, and Transportation
Protect the Relays from direct sunlight and keep the Relays under
normal temperature, humidity, and pressure.
Maximum Voltage
The maximum voltage of the coil can be obtained from the coil tem-
perature increase and the heat-resisting temperature of coil insulat-
ing sheath material. (Exceeding the heat-resisting temperature may
result in burning or short-circuiting). The maximum 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 not to exceed the maximum voltage 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 pro-
vided that the voltage is less than the maximum 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
Relays mounted on PCBs may be coated or washed. Do not apply
silicone coating or detergent containing silicone, otherwise the sili-
cone coating or detergent may remain on the surface of the Relays.
Coil Power Supply Waveform
If the voltage applied to the coil is increased or decreased gradually,
operating characteristics may be unstable, contact endurance may
decline, or the Relay may not function at its full performance level.
Therefore, always use an instantaneous ON and instantaneous OFF
when applying the voltage. Be sure that the rated voltage or zero
voltage is reached within 1 ms.

Relay.
