G6L Surface-mounting Relay
■Recommended Soldering Method for G6L
(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.
Visually check that the Relay is properly soldered.
■Approved Standards
UL recognized: UL60950 (File No. E41515)
CSA certified: C22.2 No.60950 (File No. LR31928)
■Precautions
●Please refer to “PCB Relays Common Precautions” for 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.
●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.
●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.
●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
characteristics will be maintained.
Secure the claws to the area indicated by shading. Do not attach them to
the center area or to only part of the Relay.
●Environmental Conditions During Operation, Storage,
and Transportation
Protect the Relays from direct sunlight and keep the Relays
under normal temperature, humidity, and pressure.
●Maximum Allowable Voltage
• The maximum 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 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 provided 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 silicone coating or detergent may remain on the surface of
the Relays.
