    ■ !Caution (Storage and Operating Conditions)This product is designed for application in an ordinary environment (normal room temperature, humidity and atmospheric pressure). Do not use under the following conditions because all these factors can deteriorate the product characteristics or cause failures and burn-out.1. Corrosive gas or deoxidizing gas (Chlorine gas, Hydrogen sulfide gas, Ammonia gas, Sulfuric acid gas, Nitric oxide gas, etc.)

    2. Volatile or flammable gas3. Dusty conditions4. Under vacuum, or under high or low-pressure5. Wet or humid locations6. Places with salt water, oils, chemical liquids or organic solvents7. Strong vibrations8. Other places where similar hazardous conditions exist

    ■ !Caution (Others)Be sure to provide an appropriate fail-safe function on your product to prevent secondary damages that may be caused by the abnormal function or the failure of our product.

    ■ Notice (Storage and Operating Conditions)To keep solderability of product from declining, thefollowing storage condition is recommended.1. Storage condition: Temperature -10 to +40 degrees C Humidity less than 75%RH (not dewing condition)2. Storage term: Use this product within 6 months after delivery by first-in and first-out stocking system.

    3. Handling after unpacking: After unpacking, reseal product promptly or store it in a sealed container with a drying agent.4. Storage place: Do not store this product in corrosive gas (Sulfuric acid gas, Chlorine gas, etc.) or in direct sunlight.

    ■ Notice (Soldering and Mounting) NXF SeriesPlease notice as shown below when you mount this product.1. Do not melt the solder in resin head, when you solder this product. If you melt the solder in resin head, it has posibility that the break of wire, short and break of lead insulation. In case you cut the lead wire of this product less than 20mm from resin head, the heat of melted solder at lead wire edge is propagated easily to the resin head along the lead wire.

    2. Do not touch the resin head directly by solder iron. It may cause the melt of solder in resin head.3. Do not separate the parallel lead wires 10mm or less from theresin head, when you separate parallel lead wires.4. If you mold by resin this product, please evaluate the qualityl of this product before you use it.5. Do not bend the lead wire radius 1mm or less when you bend the lead wire.

    ■ Notice (Handling)1. The ceramic element of this product is fragile, and care must be taken not to load an excessive press-force or not to give a shock at handling. Such forces may cause cracking or chipping.2. Do not apply an excessive force to the lead. Otherwise, it may cause junction between lead and element to break or crack. Holding element by side lead wire is recommended when lead wire is bent or cut.
