PrintG6K Surface-Mounting Relay
Surface-Mounting Relay with the World's Smallest Mounting Area
- Subminiature model as small as 5.2 (H) × 6.5 (W) × 10 (L) mm is ideal for high-density mounting (G6K(U)-2F(-Y)).
- Low profile of 5.2 mm improves mounting efficiency (G6K(U)-2F(-Y)).
- Light weight of 0.7 g contributes to higher speed mounting.
- Surface mounting terminal models incorporate a unique terminal structure with high infrared irradiation efficiency which allows the terminal temperature to rise easily when mounting the IRS, thus ensuring excellent soldering.
- Ensures a dielectric strength of 1,500 VAC and conforms to FCC Part 68 (i.e., withstanding an impulse withstand voltage of 1,500 V for 10 × 160 νs).
- -Y models offer an impulse withstand voltage of 2,500 V for 2 × 10 νs (conforms to Telcordia specifications) by optimizing the distance between coil and contacts.
- Standard model conforms to UL/CSA standards, certified by BSI (EN60950).
- Models available with a 2.54-mm terminal pitch.
- Rated carry current: 2A.

| Note: | 1. | When ordering, add the rated coil voltage to the model number. | |
| Example: G6K-2F |  | ||
| However, the notation of the coil voltage on the product case as well as on the packing will be marked as □□ VDC. | |||
| 2. | When ordering tape packing, add -TR" to the model number. 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 2 reels (900 pcs ✕ 2 = 1,800 pcs). | ||
| 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. | ||

Correct Use
●Long-term Continuously ON Contacts
Using the Relay in a circuit where the Relay will be ON continu- ously 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 moisture- proof package. If the Relay is left for a long time after opening the moisture-proof package, the appearance may suffer and seal fail- ure 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℃. Do not put the Relay in a cold cleaning bath immediately after soldering.
●Soldering
Soldering temperature: Approx. 250℃ (260℃ 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, make sure to set the secur- ing force of each claw to the following so that the Relays charac- teristics will be maintained.
●Environmental Conditions During Operation, Storage, and Transportation
Protect the Relay from direct sunlight and keep the Relay under normal temperature, humidity, and pressure. If the Relay is stored for a long time in an adverse environment with high temperature, high humidity, organic gases, or sulfide gases, sulfide or oxide films will form on the contact surfaces. These films may result in unstable contact, contact problems, or functional problems. Therefore, operate, store, or transport the product under specified environmental conditions.
●Latching Relay Mounting
·Make sure that the vibration or shock that is generated from other devices, such as relays in operation, on the same panel and imposed on the Latching Relay does not exceed the rated value, otherwise the Latching Relay that has been set may be reset or vice versa. The Latching Relay is reset before shipping. If exces- sive vibration or shock is imposed, however, the Latching Relay may be set accidentally. Be sure to apply a reset signal before use.
●Maximum Allowable Voltage
The maximum allowable 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 maxi- mum allowable voltage also involves important restrictions which include the following:
Must not cause thermal changes in or deterioration of the insu- lating material.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 beyond the value 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 allowable volt- age. It must be noted that continuous voltage application to the coil will cause a coil temperature increase thus affecting charac- teristics such as electrical life and resulting in the deterioration of coil insulation.
●Coating
The Relay mounted on the PCB may be coated or washed but do not apply silicone coating or detergent containing silicone, other- wise the silicone coating or detergent may remain on the surface of the Relay.
●PCB Mounting
If two or more Relays are closely mounted with the long sides of the Relays facing each other and soldering is performed with infrared radiation, the solder may not be properly exposed to the infrared rays. Be sure to keep the proper distance between adja- cent Relays as shown below.
