8 / 8 page RD 8 NOTES 1. Coil operating power Pure DC current should be applied to the coil.The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, check it with the actual circuit since the characteristics may be slightly different. The nominal operating voltage should be applied to the coil for more than 50 ms to set/reset the latching type relay. Please use the latching type for circuits that are continually powered for long periods of time. 2. Coil connection When connecting coils, refer to the wiring diagram to prevent mis-operation or malfunction. 3. Connection of coil indicator and washing conditions 1) The connection of coil indicator terminal shall be done by soldering. Soldering conditions Max. 260°C 500°F (solder temp) within 10sec (soldering time) Max. 350°C 662°F (solder temp) within 3sec (soldering time) 2) This product is not sealed type, therefore washing is not allowed. 4. Usage, transport and storage conditions 1) Ambient temperature, humidity, and atmospheric pressure during usage, transport, and storage of the relay: (1) Temperature: –55 to +85°C –67 to +185°F (2) Humidity: 5 to 85% RH (Avoid freezing and condensation.) The humidity range varies with the temperature. Use within the range indicated in the graph below. (3) Atmospheric pressure: 86 to 106 kPa Temperature and humidity range for usage, transport, and storage: 2) Condensation Condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. Condensation will cause deterioration of the relay insulation. 3) Freezing Condensation or other moisture may freeze on the relay when the temperature is lower than 0°C 32°F. This causes problems such as sticking of movable parts or operational time lags. 4) Low temperature, low humidity environments. The plastic becomes brittle if the relay is exposed to a low temperature, low humidity environment for long periods of time. 5) Low-temperature and low-humidity atmosphere. When exposed to low temperature and low humidity for a long time, the relay’s plastic casing may become breakable. 5. Other handling precautions. 1) The relay’s on/off service life is based on standard test conditions (temperature: 15 to 35°C 59 to 95°F, humidity: 25 to 75%) specified in JIS C5442-1996. Life will depend on many factors of your system: coil drive circuit, type of load, switching intervals, switching phase, ambient conditions, to name a few. 2) Use the relay within specifications such as coil rating, contact rating and on/off service life. If used beyond limits, the relay may overheat, generate smoke or catch fire. 3) Be careful not to drop the relay. If accidentally dropped, carefully check its appearance and characteristics before use. 4) Be careful to wire the relay correctly. Otherwise, malfunction, overheat, fire or other trouble may occur. 5) The latching type relay is shipped in the reset position. But jolts during transport or impacts during installation can move it to the set position. It is, therefore, advisable to build a circuit in which the relay can be initialized (set and reset) just after turning on the power. 6) If a relay stays on in a circuit for many months or years at a time without being activated, circuit design should be reviewed so that the relay can remain non-excited. A coil that receives current all the time heats, which degrades insulation earlier than expected. A latching type relay is recommended for such circuits. 7) For SMA connectors, we recommend a torque of 0.90±0.1 N·m for installation, which falls within the prescribed torque of MIL-C-39012. Please be aware that conditions might be different depending on the connector materials and how it interacts with surrounding materials. 8) Please do not use silicon based substances such as silicon rubber, silicon oil, silicon coatings and silicon fillings, in the vicinity of the relay. Doing so may cause volatile silicon gas to form which may lead to contact failure due to the adherence of silicon on the contacts when they open and close in this atmosphere.
