Installation, commissioning		Laws and/or regulations and standards governing the use or intended usage goal must be observed. The adhesive label provided must be affixed in the immediate vicinity of the sensor! The surface to which the label is applied must be clean, flat and free from grease! The affixed adhesive label must be readable and durable, taking account of the possibility of chemical corrosion!
Maintenance		No changes can be made to apparatus, which are operated in hazardous areas. Repairs to these apparatus are not possible.
Special conditions
	Minimum series resistance RV	A minimum series resistance RV is to be provided between the power supply voltage and the proximity switch in accordance with the following list. This can also be assured by using a switch amplifier.
	Maximum operating voltage UBmax	The maximum permissible operating voltage UBmax must be restricted to the values given in the following list. Tolerances are not permitted.
	Maximum permissible ambient temperature TUmax	Values can be obtained from the following list, depending on the max. operating voltage Ub max and the minimum series resistance Rv.

Важная информация

Все информационные материалы, представленные на сайте, носят справочный характер и не могут в полной мере передавать достоверную информацию о свойствах и характеристиках товара.

Фотография на сайте служит дополнительным источником для определения совместимости запчастей с Вашим оборудованием, и не может являться основным. Основной источник по совместимости запчастей - актуальная документация производителя оборудования, из которой значимой информацией для заказа являются: название запчасти и каталожный номер.

Запасные части и комплектующие подбираются самостоятельно покупателем строго по каталожным номерам из официальных деталировок производителей. В случае, если номенклатура товара совпадает с фактически поставленной, но не подходит на оборудование - в ее замене или возврате может быть отказано.

Цены на сайте имеют информационный характер и могут отличаться от цен в коммерческом предложении.
