## ■Other things to observe - Exceeding the stipulated conditions when soldering may affect coaxial switch performance. Be sure to consult us beforehand. - Since thermal stress on a relay will depend on the PC board and process conditions, please be sure to test using the actual PC board. - Creep-up, wettability and solder strength will differ depending on changes in the mounting conditions and type of solder. Please evaluate based on actual production conditions. - Only apply coating after the relay has returned to room temperature. Panasonic Industry Co., Ltd.

But jolts during transport or impacts during installation can change the reset 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. ## ●External magnetic field Since TQ relays are highly sensitive polarized relays, their characteristics will be affected by a strong external magnetic field. Avoid using the relay under that condition. - Precautions for usage of automatic insertion machine Set the chucking pressure of the pick-up mechanism by the automatic mounting machine with the pressure shown in table 1 to maintain the internal function of the relay. **==> picture [123 x 115] intentionally omitted <==** **----- Start of picture text -----**

Panasonic Industry Co., Ltd. Electromechanical Control Business Division industrial.panasonic.com/ac/e/ ASCTB14E 202301 ー 16 ー Panasonic Industry Co., Ltd. 2023 GUIDELINES FOR SIGNAL RELAYS 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 ## ■Long term current carrying A circuit that will be carrying a current continuously for long periods without relay 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. ## ■ **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. - ●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 operate 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 ℃, 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 operate voltage and the operate voltage rises in accordance with the increase in the resistance value. However, for some polarized relays, this rate of change is considerably smaller. Panasonic Industry Co., Ltd. Electromechanical Control Business Division industrial.panasonic.com/ac/e/ > Panasonic Industry Co., Ltd. 2022 ASCTB414E 202210 ー 17 ー GUIDELINES FOR SIGNAL RELAYS USAGE ## NOTES ■ **Usage, Storage, and Transport Conditions** During usage, storage, or transportation, avoid locations subject to direct sunlight and maintain normal temperature, humidity, and pressure conditions. The allowable specifications for environments suitable for usage, storage, and transportation are given below. - 1) Temperature: - The allowable temperature range differs for each relay, so refer to the relay's individual specifications. In addition, when transporting or storing relays while they are tube packaged, there are cases when the temperature may differ from the allowable range. In this situation, be sure to consult the individual specifications. - 2) Humidity: 5 to 85% RH - The humidity range varies with the temperature. Use within the range indicated in the graph. - ( The allowable temperature depends on the relays. ) **==> picture [165 x 142] intentionally omitted <==** **----- Start of picture text -----**

## ●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 Industry Co., Ltd. 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 ℃. This icing causes the sticking of movable portion, the operation delay and the contact conduction failure etc. Panasonic Industry Co., Ltd. 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. - 3) Pressure: 86 to 106 kPa - ●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. Panasonic Industry Co., Ltd. Electromechanical Control Business Division industrial.panasonic.com/ac/e/ > Panasonic Industry Co., Ltd. 2022 ASCTB414E 202210 ー 18 ー GUIDELINES FOR SIGNAL RELAYS USAGE - ●Storage requirements Since the surface-mount terminal 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 ℃ / 70% RH ). 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. - 2) If relays will not be used within 72 hours, please store relays in a humidity controlled desiccator or in an antihumidity 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. - 3) When relays ( which is packaged with humidity indicator and silica gel ) meeting one of below criteria, please bake ( dry ) before use. - When the storage conditions specified in 1) are exceeded. - When humidity indicator is in Ⅲ or Ⅳ status according to judgement standard. Please check humidity indicator color and decide if baking is necessary or not. - ●: indicate brown, ○: Other than brown ( blueish color ) **==> picture [227 x 68] intentionally omitted <==** **----- Start of picture text -----**

- 4 ) The following cautionary label is affixed to the antihumidity pack. **==> picture [232 x 146] intentionally omitted <==** ## ●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 ℃ ). If use at high humidity is unavoidable, please contact our sales representative. - ＜Baking ( Drying ) conditions＞ - With reel : 45 ℃, 96 hours or more. **==> picture [98 x 71] intentionally omitted <==** - Without reel ( including relay only ): 60 ℃, 35 hours or more.

Electromechanical Control Business Division industrial.panasonic.com/ac/e/ > Panasonic Industry Co., Ltd. 2022 ASCTB414E 202210 ー 19 ー GUIDELINES FOR SIGNAL RELAYS USAGE ## OTHERS ## ■Cleaning - 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. - Surface-mount terminal type relay is sealed type and it can be cleaned by immersion. - Cleaning with the boiling method is recommended ( The temperature of cleaning liquid should be 40℃ 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. - Use pure water or alcohol-based cleaning solvent.
