(11/11) S E N S O R S CHS series Handling Precautions For CHS series products of all types Please request a delivery specification form containing more detailed information on characteristics and specifications so as to ensure correct and safe use of the products. Operating life of the products becomes shorter depending on the environmental conditions. If you are concerned with the stable operation period, please confirm the operating life in the actual environment in advance. [Storage Environment] Check the standards concerning the storage conditions described in the delivery specifications of the products, and store them in accordance with the standards. It is recommended that the products be stored in an airtight container with silica gel. Do not store this product in an environment in which corrosive gases are generated, entered, or stagnated, or in dusty environments. Storage in high temperature and high-humidity environments, environments where condensation occurs, or environments where sudden tempera- ture changes occur may cause deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range. If the products have been stored in such environments, check their characteristics before use. Storage in environments where products may come into contact with water or saltwater may cause deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range. If the products have been stored in such environments, check their characteris- tics before use. Storage for an extended period of time may cause deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guar- anteed range. If the products have been stored for an extended period of time, check their characteristics before use. [Usage Environment/Operating Conditions] As for usage environment conditions and operating conditions of the products, check the standards concerning the usage environment conditions and operating conditions described in the delivery specifications, and use the products in accordance with the standards. The generation, influx, or stagnation of corrosive gases or a large amount of dust may become a cause of deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range. High temperature and high humidity, condensation, or sudden temperature changes may become a cause of deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range. Environments where the products come into contact with water or saltwater may become a cause of deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range. [Handling] Do not apply excessive mechanical shock such as dropping to the products. Do not cover the sensing surface of the products when mounting. Be careful not to apply excessive stress on the main unit when forming terminals. In a process such as flow soldering where flux decomposition gas is generated, take measures such as temporarily sealing the opening of the main unit to keep corrosive gas from entering (corrosive gas may become a cause of deterioration of the moisture sensitive film, resulting in fluctuations of output exceeding the guaranteed range). Element type [Usage Environment/Operating Conditions] The rated voltage of this product is "AC (Eac) 5Vmax". Please be reminded that serious damage such as electrolysis or peeling of the moisture sensitive material may occur if a direct current is applied to the products. In addition, please keep in mind that there may be effects similar to direct current applica- tion even when applying an alternating current, due to (1) residual direct current or (2) asymmetrical waveforms. Other Requests/Notices We do not assume any responsibility for any damage caused by the use of our products exceeding the scope or conditions defined in the delivery speci- fications. Specifications of the products in this catalog are subject to change without notice due to improvements or other reasons. In addition, supply of the prod- ucts may be cancelled without notice.
