( circuits polarity ( ＋, − ) at the internal connection diagram for emergency lamps, alarm devices and error inspection that, for example, revert only during malfunction and ( Schematic ). If any wrong connection is made, it may cause unexpected malfunction, like abnormal heat, fire and output warnings with form B contacts ) Continuous, long- so on, and circuit do not work. Avoid impressing voltages to term current to the coil will facilitate deterioration of coil insulation and characteristics due to heating of the coil itself. the set coil and reset coil at the same time. 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. ■ Maximum allowable voltage and temperature rise ■ 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. 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 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.

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. ) 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 sealed 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. Panasonic Industry Co., Ltd.

Doing so may deteriorate the Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may cause breaks in the coil or slight sticking of sealing performance. the contacts due to ultrasonic energy.
