IRS Method (for surface-mounting terminal models) Soldering Preheating Time (s) * The thickness of cream solder to be applied should be within a range between 150 and 200 m 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 left side. Correct Soldering Incorrect Soldering Relay PCB Terminal Solder Land Insufficient amount of solder Excessive amount of solder Visually check that the Relay is properly soldered. Approved Standards UL approval: UL1950 (File No. E41515) CSA approval: C22.2 No. 950 (File No. LR24825) 222 Model Coil ratings Contact ratings Number of test operations DPDT G6K-2G(F/P): 3 to 12 VDC G6K(U)-2G(F/P)-Y: 3 to 24 VDC 1 A at 30 VDC 0.5 A at 60 VDC 0.3 A at 125 VAC 6,000 Surface-Mounting Signal Relay - G6K CORRECT USE Handling Leave the Relay unpacked until mounting it. Soldering Solder: JIS Z3282, H63A Soldering temperature: Approx. 250C (260C 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 make a molten solder level adjustment so that the solder will not overflow on the PCB. 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 Relays characteristics are maintained. Direction A: 1.96 N Direction B: 4.90 N Direction C: 1.96 N 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 sulphide gases, sulphide 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 excessive 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 maximum allowable 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 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 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 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. 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 adjacent Relays as shown below. G6K-2G 2 mm min. G6K-2F 2.7 mm min. Two or more Relays may be closely mounted with the short sides of the Relays facing each other. 223 Signal Relays Precautions
