Manufacturer: Pepperl+Fuchs
Description:

Pepperl+Fuchs inductive proximity sensors are essential components in automation and control systems, widely used for detecting the presence or absence of metallic objects without physical contact. These sensors utilize inductive technology to generate an electromagnetic field, which is disrupted when a metallic object enters the sensing range. This technology enables them to function effectively in environments where traditional mechanical switches may fail due to wear or contamination.

Common applications of inductive sensors include position sensing, object counting, and safety monitoring in manufacturing processes. Their robust design allows them to withstand extreme temperatures, vibrations, and exposure to dust and moisture, making them suitable for use in a variety of industries, including automotive, packaging, and materials handling. The versatility of these sensors ensures they can be integrated seamlessly into existing systems to enhance operational efficiency and reliability.

Specific conditions
Lead insertion The connection cables should either be fixed when laid and mechanically protected or installed in such a way, that a force of 30 N applied in the direction of the cable inlet for one hour, does not lead to any visible displacement of the cable connections, even though the cable sheathing is displaced, see also IEC 60079-11. Depending on the type of installation, a suitable cable in accordance with Type A oder B of IEC 60079-14, must be used.
ATEX 2G
Specific conditions
Lead insertion The connection cables should either be fixed when laid and mechanically protected or installed in such a way, that a force of 30 N applied in the direction of the cable inlet for one hour, does not lead to any visible displacement of the cable connections, even though the cable sheathing is displaced, see also IEC 60079-11. Depending on the type of installation, a suitable cable in accordance with Type A oder B of IEC 60079-14, must be used.
