  • Temperature Sensor Thermo String/Lead Type !Caution/Notice

    c !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 of these factors can deteriorate the product characteristics or cause failures and burn-out.1. Corrosive gas or deoxidizing gas (Chlorine gas, Hydrogen sulfi de gas, Ammonia gas, Sulfuric acid gas, Nitric oxide gas, etc.)

    2. Volatile or fl ammable 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

    c !Caution (Others)

    c Notice (Storage and Operating Conditions)

    c Notice (Rating)Use this product within the specifi ed temperature range.Higher temperature may cause deterioration of the characteristics or the material quality of this product.

    c Notice (Soldering and Mounting) NXF Series

    Continued on the following page.

    Be sure to provide an appropriate fail-safe function on your product to prevent secondary damage that may be caused by the abnormal function or the failure of our product.

    To keep the solderability of the product from degrading, the following storage condition is recommended.1. Storage condition: Temperature -10 to +40C Humidity less than 75%RH (not dewing condition)2. Storage term: Use this product within 6 months after delivery by fi rst-in and fi rst-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.

    Please note as shown below when you mount this product.1. Do not melt the solder in the resin head when you solder this product. If you do so, there is a possibility of wire breakage, electric short mode failure and wire coating breakage. If you cut the lead wire of this product less than 20mm from the resin head, the heat of the melted solder at the lead wire edge is propagated easily to the resin head along the lead wire.

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

    c Notice (Soldering and Mounting) NXR Series (Insulation Type)

    c Notice (Handling) NXF/NXR Series1. The ceramic element of this product is fragile, and care must be taken not to load an excessive press-force or not to cause a shock at handling. Such forces may cause cracking or chipping.2. Do not apply excessive force to the lead. Otherwise, it may cause the junction between lead and element to break or crack. Holding the element by the side lead wire is recommended when lead wire is bent or cut.

    c Notice (Handling) NXR Series (Insulation Type)1. The ceramic element of this product is fragile, and care must be taken not to load an excessive press-force or not to cause a shock at handling. Such forces may cause cracking or chipping. Especially under high-temperature environment, there is a possibility that epoxy resin will become soft. When you set up the processing environment, please examine the processing method after evaluating the quality of this product.

    2. Do not apply excessive force to the lead. Otherwise, it may cause the junction between lead and element to break or crack. Holding the element by the side lead wire is recommended when lead wire is bent or cut. Handle the lead with care; there is a possibility that a crack may go into the polyurethane insulated coat when bending the lead.

    Please note as shown below when you mount this product.1. Do not melt the solder in the resin head, when you solder this product. If you melt the solder in resin the head, the wire could break and short. If you cut the lead wire of this product less than 8mm from the resin head, the heat of the melted solder at the lead wire edge is propagated easily to the resin head along the lead wire. Please do not cut this product below 9mm.

    2. Do not touch the resin head directly with the solder iron. It may cause the melting of solder in the resin head.3. If you mold this product with resin, please evaluate the quality of this product before you use it.

    Please note as shown below when you mount this product.1. Do not melt the solder in the resin head when you solder this product. (more than 25mm in full length of the product). If you melt the solder in the resin head, it has posibility that the wire could break and short.2. Do not touch the resin head directly with the solder iron. It may cause the melting of solder in the resin head.3. When additonal processing is carried out on this product (such as bonding, resin molding, and resin coating, etc.), please perform an audit of quality level on an automated machine and only use the product after confi rming its reliability.

    Please talk to us if you have concern matter, like process it under the high temperature and the high pressure. (For example, exposed to high-temperature and high-pressure environment as mold sealing with injection molding.)
