Pepperl+Fuchs NBB20-U4-Z2 standard inductive sensor. Series: VariKont ®, Housing material: PA/metal with epoxy powder coating, Output type: 2-wire, Installation: flush, Type of voltage: DC, Connection type: screw terminals, Degree of protection: IP68 / IP69K.
VariKont inductive sensors feature increased switching distances of 30 mm flush and 50 mm non-flush. Both sensor versions are easy to install and enable object detection at long distances. This means more flexibility in system planning and simultaneous cost reduction. The VariKont and VariKont L2 sensors are equipped with a primary and secondary coil. Much like other sensors, the primary coil is used to detect the target. The secondary coil, on the other hand, measures the sensor environment—the installation and the material surrounding it. This information is used to immediately compensate for ambient conditions.

Highlights
● Active Shielding Technology ensures high switching distances, no matter the installation situation
● More flexibility: switching distances up to 30 mm (flush) and 50 mm (non-flush) for easier equipment design
● High visibility corner LEDs enable status checks at any time and from any perspective.
● Both versions of the sensor feature an adjustable sensor head and offer user-friendly installation and replacement. The sensor head can be rotated in five directions for optimal alignment with the target.
● Meets the highest standards: internal quality testing goes above and beyond the requirements of target industry machine applications
