Precautions
Use a DC power supply with 5% or less ripple factor to operate
the coil.
Do not use the G6S where subject to strong external magnetic
fields.
Do not use the G6S where subject to magnetic particles or excessive amounts of dust.
Do not reverse the polarity of the coil (+,
Latching types are delivered in the reset position. We recommend
that a reset voltage be applied in advance to start operation.
Do not drop the G6S or otherwise subject it to excessive shock.
Remove the relay from the packing immediately prior to usage.
Precautions
■
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.
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 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.
−).
G6S-2G, G6SU-2G, G6SK-2G, G6S-2G-Y
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.
G6S (K) (-U) -2 Soldering
• Soldering temperature: Approx. 250°C (At 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, be sure to set the securing
force of each claw to the following so that the Relay’s characteristics will be maintained.
