All description
Manufacturer: Pepperl+Fuchs
Description:

The inductive sensors in the VariKont series are engineered for robust performance in various industrial environments. Utilizing advanced sensing technology, these sensors detect metallic objects without direct contact, ensuring a long operational life and minimizing maintenance requirements. They are particularly effective in applications involving automation, material handling, and packaging.

These sensors feature a flush installation design and are constructed from durable PA/metal housing, making them suitable for integration into a wide array of equipment. With a rated operating distance of 15 mm and a 2-wire output type, they provide reliable signaling in DC voltage applications. Additionally, their compliance with ATEX 3G standards allows for safe operation in potentially explosive atmospheres, further enhancing their applicability in industrial settings.
