An attention matter on security I undertake use with this product, and it is paid attention enough, and please design an attention matter safely. Attention on a design When you designs a base of an electric circuit. Please use size of the hole or pad which we recommend. Magnetic flux to leak out occurs. Please confirm it about influence of magnetic flux beforehand. There is fear to cause false movement of machinery. In a design of a base of an electric circuit, Please consider the next contents. In an applied safe standard. The trans and distance with other parts The product is not quakeproof structure. Accordingly please do not add vibration and a shock to it. There is fear to lose a function. Attention on the handling Please do not use it when you let a product drop. The product produces possibility to lose a function Please pay attention to the pin which had it pointed keenly. There is danger to injure. Please avoid the next place. The place that receives a drop of water, trash, the dust, foggy influence. The place where direct rays of the sun hits. There is fear to cause false movement of machinery. Please prohibit safekeeping and use at the next place. Environment to be accompanied with gas corrosion, salt, acid, alkali. There is fear to lose a function. When you carry the product on a base of an electric circuit. Please do not use a metal tool. Because impossible power is added to a product. There is fear to lose a function. Attention I considered the next matter, and we designed a product. Safe standard and power supply voltage and circuit drive condition, drive frequency and Duty ON-TIME. By those conditions, we decided structure and the turns number. Please avoid use in designed condition outside. There are destruction of a circuit part and fear of ignition. This product considered a characteristic of a component and a self temperature rise, and it was made. We select range of humidity as use temperature already. Please avoid use by range more than this. There are the damage and fear of ignition. Please avoid use in the environment next. The environment that trash and the dust stick to a product. There is fear to cause a fire.
