This moisture may react with the NOx and varies depending on parameters such as the type of load, switching frequency, driver circuit, and ambient temperature under the actual operating conditions. Evaluate the performance by using the actual circuit before SOx generated by glow discharges that occur when the contacts are opened or closed, producing nitric or sulfuric acid. If this happens, the acid produced may corrode the metallic parts of the relay, causing operational malfunction. using the relay. 2. Driving relays - If the internal connection diagram of a relay shows + and symbols on the coil, apply the rated voltage to the relay in the specified direction. If a rippled DC current source is used, abnormalities such as beat at the coil may occur. - If any material containing silicon (silicon rubber, silicon oil, and silicon based coating material) is used in the neighborhood of relay, there is some possibility that these materials will emit silicon gas that will penetrate the relay. In - The maximum voltage that can be applied to the coil of the this case, the switching contact may generate silicon relay compounds on the surface of contacts.

Keep the force applied to the relay to within 1 kg. - Avoid bending the pins to temporarily secure the relay to the PC board. Bending the pins may degrade sealability or adversely affect the internal mechanism. - It is recommended to solder the relay onto a PC board under the following conditions: <1> Reflow soldering Refer to the recommended soldering temperature profile. <2> Flow soldering Solder temperature: 260°C max., Time: 5 seconds max. Preheating: 110~ 120°C /110 sec. (max.) <3> Manual soldering Solder temperature: 350°C, Time: 2~3 seconds - Ventilation immediately after soldering is recommended. Avoid immersing the relay in cleaning solvent immediately after soldering due to the danger of thermal shock being applied to the relay. - Use an alcohol-based or water-based cleaning solvent. Never use thinner and benzene because they may damage the relay housing. - Do not use ultrasonic cleaning because the vibration energy generated by the ultrasonic waves may cause the contacts to remain closed. 5. Handling - Relays are packaged in magazine cases for shipment. If a space is created in the case after some relays have been removed, be sure to insert a stopper to secure the remaining relays in the case. If relays are not well secured, vibration during transportation may cause malfunctioning of the contacts. - Exercise care in handling the relay so as to avoid dropping it or allowing it to fall. Do not use a relay that has been dropped. If a relay drops from a workbench to the floor, a shock of 9,800 m/s2 (1,000 G) or more is applied to the relay, possibly damaging its functions. Even if a light shock has been applied to the relay, thoroughly evaluate its operation before using it. - Latching relays are factory-set to the reset state for shipment. A latching relay may be set, however, by vibration or shock applied while being transported. Be sure to forcibly reset the relay before using it in the application set. Also note that the relay may be set by unexpected vibration or shock when it is used in a portable set. - The sealability of a surface-mount (SMT) relay may be lost if the relay absorbs moisture and is then heated during soldering. When storing relays, therefore, observe the following points: <1> For standard packing, please use relays within 12 months after delivery. (Storage conditions: 30 °C / 60% RH) If the relays have moisture absorption, dehumidify as follows. Tape packing: 50±5 °C, 200~300 hours. 14 ●All specifications in this catalog and production status of products are subject to change without notice.
