SAFETY REMINDERS Please pay sufficient attention to the warnings for safe designing when using these products. REMINDERS Please do not bring the magnet close to the product (Recommending is separating to 50cm or more). An electric characteristic might be deteriorated. The magnetic field of 5mT or more must not go into the product when you make the magnet approach. Moreover, please do not touch a soft magnetic material such as iron (Recommending is separating to 10mm or more). An electric characteristic might be deteriorated. An electric characteristic changes when bringing it close within 10mm(reversible change). There is a leakage of some magnetism (0.3T or less) from the product.
