For general cautions for use, please refer to the “General Application Guidelines”. 2. 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. Please use the latching type for circuits that are continually powered for long periods of time. 3. Coil connection Since this product is polarized, please be aware of the plus/minus polarity of the coil. 4. Connection and washing conditions for coil and PIN type contact terminals 1) The connection of coil and PIN type contact terminals 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. 5. Conditions for operation, transport and storage conditions 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: Humidity, %RH 85 Tolerance range (Avoid freezing when used at temperatures lower than 0°C 32°F) 5 –55 –67 (Avoid condensation when used at temperatures higher than 0°C 32°F) 0 +32 Temperature, °C °F +85 +185 4) Condensation Condensation forms when there is a sudden change in temperature under high temperature and high humidity conditions. Condensation will cause deterioration of coaxial switch insulation. 5) Freezing Condensation or other moisture may freeze on coaxial switch when the temperature is lower than 0°C 32°F. This causes problems such as sticking of movable parts or operational time lags. 6) Low temperature, low humidity environments. The plastic may become brittle if coaxial switch is exposed to a low temperature, low humidity environment for long periods of time. 6. Other handling precautions. 1) Coaxial switch’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 coaxial switch within specifications such as coil rating, contact rating and on/off service life. If used beyond limits, coaxial switch may overheat, generate smoke or catch fire. 3) Be careful not to drop coaxial switch. If accidentally dropped, carefully check its appearance and characteristics before use. 4) Be careful to wire coaxial switch correctly. Otherwise, malfunction, overheat, fire or other trouble may occur. 5) The latching type product 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 coaxial switch can be initialized (set and reset) just after turning on the power. 6) If coaxial switch stays on in a circuit for many months or years at a time without being activated, circuit design should be reviewed so that the coaxial switch can remain deenergized. A coil that receives current all the time heats, which degrades insulation earlier than expected. A latching type is recommended for such circuits. 7) For SMA connectors (SMA type only), 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 coaxial switch. 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. 9) In order to ensure stable signal communication on contact, it is recommended that the monitoring of contact signal should be started from Min. 100 ms after coil rated voltage is applied. Please refer to "the latest product specifications" when designing your product. • Requests to customers : https://industrial.panasonic.com/ac/e/salespolicies/ Panasonic Corporation Electromechanical Control Business Division industrial.panasonic.com/ac/e/ 6 © Panasonic Corporation 2019 ASCTB107E 201903 GUIDELINES FOR MICROWAVE DEVICES USAGE For cautions for use, please read “GUIDELINES FOR RELAY USAGE”. https://industrial.panasonic.com/ac/e/control/relay/cautions_use/index.jsp Precautions for Coil Input DC Coil operating power Steady state 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, please check with the actual circuit since the electrical characteristics may vary. The rated coil voltage should be applied to the coil and the set/reset pulse time of latching type relay differs for each relays, please refer to the relay's individual specifications. Coil connection When connecting coils of polarized relays, please check coil polarity (+,-) at the internal connection diagram (Schematic). If any wrong connection is made, it may cause unexpected malfunction, like abnormal heat, fire and so on, and circuit do not work. Avoid impressing voltages to the set coil and reset coil at the same time. Maximum allowable voltage and temperature rise Proper usage requires that the rated coil voltage be impressed on the coil. Note, however, that if a voltage greater than or equal to the maximum continuous voltage is impressed on the coil, the coil may burn or its layers short due to the temperature rise. Furthermore, do not exceed the usable ambient temperature range listed in the catalog. Maximum allowable voltage for coil In addition to being a requirement for relay operation stability, the maximum continuous impressed coil voltage is an important constraint for the prevention of such problems as thermal deterioration or deformity of the insulation material, or the occurrence of fire hazards. Temperature rise due to pulse voltage When a pulse voltage with ON time of less than 2 minutes is used, the coil temperature rise bares no relationship to the ON time. This varies with the ratio of ON time to OFF time, and compared with continuous current passage, it is rather small. The various relays are essentially the same in this respect. Current passage time (%) For continuousu passage Tempereture rise value is 100% ON : OFF = 3 : 1 About 80% ON : OFF = 1 : 1 About 50% ON : OFF = 1 : 3 About 35% ON : OFF = 1 : 1 Voltage Long term current carrying A circuit that will be carrying a current continuously for long periods without relay or microwave device switching operation. (circuits for emergency lamps, alarm devices and error inspection that, for example, revert only during malfunction and output warnings with form B contacts) Continuous, long-term current to the coil will facilitate deterioration of coil insulation and characteristics due to heating of the coil itself. For circuits such as these, please use a magnetic-hold type latching relay. If you need to use a single stable relay, use a sealed type relay that is not easily affected by ambient conditions and make a failsafe circuit design that considers the possibility of contact failure or disconnection. Time Operate voltage change due to coil temperature rise　 　(Hot start) In DC relays, after continuous passage of current in the coil, if the current is turned OFF, then immediately turned ON again, due to the temperature rise in the coil, the pick-up voltage will become somewhat higher. Also, it will be the same as using it in a higher temperature atmosphere. The resistance/temperature relationship for copper wire is about 0.4% for 1°C, and with this ratio the coil resistance increases. That is, in order to operate of the relay, it is necessary that the voltage be higher than the pick-up voltage and the pick-up voltage rises in accordance with the increase in the resistance value. However, for some polarized relays, this rate of change is considerably smaller. Ambient Environment Dew condensation Condensation occurs when the ambient temperature drops suddenly from a high temperature and humidity, or the relay and microwave device is suddenly transferred from a low ambient temperature to a high temperature and humidity. Condensation causes the failures like insulation deterioration, wire disconnection and rust etc. Panasonic Corporation does not guarantee the failures caused by condensation. The heat conduction by the equipment may accelerate the cooling of device itself, and the condensation may occur. Please conduct product evaluations in the worst condition of the actual usage. (Special attention should be paid when high temperature heating parts are close to the device. Also please consider the condensation may occur inside of the device.) Icing Condensation or other moisture may freeze on relays when the temperature become lower than 0°C.This icing causes the sticking of movable portion, the operation delay and the contact conduction failure etc. Panasonic Corporation does not guarantee the failures caused by the icing. The heat conduction by the equipment may accelerate the cooling of relay itself and the icing may occur. Please conduct product evaluations in the worst condition of the actual usage. Panasonic Corporation Electromechanical Control Business Division industrial.panasonic.com/ac/e/ Low temperature and low humidity The plastic becomes brittle if the switch is exposed to a low temperature, low humidity environment for long periods of time. High temperature and high humidity Storage for extended periods of time (including transportation periods) at high temperature or high humidity levels or in atmospheres with organic gases or sulfide gases may cause a sulfide film or oxide film to form on the surfaces of the contacts and/or it may interfere with the functions. Check out the atmosphere in which the units are to be stored and transported. Package In terms of the packing format used, make every effort to keep the effects of moisture, organic gases and sulfide gases to the absolute minimum. c Panasonic Corporation 2019 ASCTB403E 201905 GUIDELINES FOR MICROWAVE DEVICES USAGE Storage requirements Since the SMD type is sensitive to humidity it is packaged with tightly sealed anti-humidity packaging. However, when storing, please be careful of the following. 1) Please use promptly once the anti-humidity pack is opened.(within 72 hours, Max. 30°C/70% R.H.). If left with the pack open, the relay will absorb moisture which will cause thermal stress when reflow mounting and thus cause the case to expand. As a result, the seal may break. *For RE relays, after this bag is opened, the product must be used within 24 hours. 2) If relays will not be used within 72 hours, please store relays in a humidity controlled desiccator or in an anti-humidity bag to which silica gel has been added. *If the relay is to be soldered after it has been exposed to excessive humidity atmosphere, cracks and leaks can occur. Be sure to mount the relay under the required mounting conditions *For RE relays, after this bag is opened, the product must be used within 24 hours. 3) The following cautionary label is affixed to the anti-humidity pack. Silicon When a source of silicone substances (silicone rubber, silicone oil, silicone coating materials and silicone filling materials etc.) is used around the relay, the silicone gas (low molecular siloxane etc.) may be produced. This silicone gas may penetrate into the inside of the relay. When the relay is kept and used in this condition, silicone compound may adhere to the relay contacts which may cause the contact failure. Do not use any sources of silicone gas around the relay (Including plastic seal types). NOx Generation When relay is used in an atmosphere high in humidity to switch a load which easily produces an arc, the NOx created by the arc and the water absorbed from outside the relay combine to produce nitric acid. This corrodes the internal metal parts and adversely affects operation. Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use at high humidity is unavoidable, please contact our sales representative. *RE Relays only Others Cleaning 1) Although the environmentally sealed type relay (plastic sealed type, etc.) can be cleaned, avoid immersing the relay into cold liquid (such as cleaning solvent) immediately after soldering. Doing so may deteriorate the sealing performance. 2) Surface mount terminal type relay is sealed type and it can be cleaned by immersion. Use pure water or alcohol-based cleaning solvent. 3) Cleaning with the boiling method is recommended (The temperature of cleaning liquid should be 40°C or lower). Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may cause breaks in the coil or slight sticking of the contacts due to the ultrasonic energy. Other handling precautions ・Expected switching life is defined under the standard test conditions (temperature 15 to 35°C, humidity: 25 to 75%) specified in JIS C 5442. Expected switching life is depend on usage conditions; coil driving circuit, load type, activation frequency, activation phase, ambient conditions and other factors. Please check relays and microwave devices on the actual circuit. Also, pay special attention loads such as those listed below. ・When used for AC load-operating and the operating phase is synchronous, rocking and fusing can easily occur due to contact shifting. ・Frequent switching under load condition When high frequently switched under load condition that can cause arc at the contacts, nitrogen and oxygen in the air is fused by the arc energy and HNO3 is formed. This can corrode metal materials. Countermeasures for these are. 1. Incorporate an arc-extinguishing circuit. 2. Lower the operating frequency 3. Lower the ambient humidity ・When used for ‘‘Dry switching’’ without load current, please contact our sales representative. ・Please avoid relays to be used outside of the specification ranges such as the coil rating, contact rating and switching life that may cause abnormal heating, smoke, and fire. ・In case relays and microwave devices are dropped, please do not use. Please refer to "the latest product specifications" when designing your product. •Requests to customers: https://industrial.panasonic.com/ac/e/salespolicies/ Panasonic Corporation Electromechanical Control Business Division industrial.panasonic.com/ac/e/ c Panasonic Corporation 2019 ASCTB403E 201905 Please contact ..........
