10 1. This sensor generates very strong suction because this product contains a permanent magnet. Be careful not to apply mechanical shock when handling the sensor. 2. Do not place this product near magnetic recording media such as magnetic tapes or floppy disks. Magnetic recording could be damaged. 3. Do not place this product near a person who has an electronic medical device. It is very dangerous and may cause malfunction of an electronic medical device. n Notice (Storage and Operating Condition) 1. Please avoid water, chemical solvent or oil. 2. Please avoid corrosive gas (Chlorine gas,...
