104 High Frequency Relay G6K-RF
Precautions
■Recommended Soldering Method
3.
The thickness of cream solder to be applied should be between 200 and 250
μ
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 using the soldering conditions
shown above. Check the soldering in the actual mounting conditions prior to use.
■Precautions for correct use
For general precautions, refer to Omron’s Relay Technical guidelines, contained in Omron’s relay catalog.
Relay Handling
Do not unpack the relay until ready to mount it. Use the relay as soon as
possible after opening the moisture-proof bag. Otherwise, the terminals
may tarnish and seal failure may occur after the solder process.
When washing the product after soldering, use a water-based or
alcohol-based solvent. Keep the solvent temperature below 40°C.
Do not put the relay in a cold cleaning bath immediately after soldering.
Operating, Storage Environment
If the relay is stored for a long time in an adverse environment with high
temperature, high humidity, organic or sulfide gases, then sulfide or
oxide films will form on the contact surfaces. These films may result in
unstable contact, contact problems or function problems. Therefore,
operate, store or transport the product under specified environmental
conditions.
1. Use in locations where the relay is not exposed to corrosive
gas such as hydrogen sulfide gas or salty air.
2. Use in locations where no visible dust exists.
3. Use, store and transport in locations where the product is not
exposed to direct sunlight, rain or snow.
4.
Do not apply force to the product which may result in deformation
or change in quality of the product.
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.
Latching Relay Mounting
Make sure that excess vibration or shock doesn’t set or reset the
relay during normal operation. The relay is shipped in the ‘reset’
position.
Shock or vibration during shipping may require the application
of a reset signal, prior to operation.
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 relay’s characteristics
will be maintained.
Maximum Allowable Voltage
The maximum allowable voltage of the coil can be obtained from the
coil temperature increase and the heat-resisting temperature of the
coil insulating sheath material. (Exceeding the heat-resisting tem-
perature 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, which may result in films developing on the contacts.
• 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 as specified in
the catalog. As a rule, the rated voltage must be applied to the coil. Con-
sider using a latching relay instead of a non-latching relay with a continu-
ous voltage applied to the coil.
Long-term, Continuous ON contacts
Using the relay where it will remain continuously energized for long
periods of time can lead to unstable contacts. We recommend using
a latching relay for this type of application.
