The NBB2 - 6.5M25 - E2 - V3 from Pepperl + Fuchs is an inductive sensor designed for precise object detection. It has a rated operating distance of 2 mm, with an assured operating distance spanning from 0 to 1.62 mm. This allows it to accurately sense metallic objects in industrial applications. Its normally open switching function and PNP output type make it highly compatible with various control systems. The sensor also takes into account different materials, featuring reduction factors such as 0.4 for aluminum ((r_{al})), 0.3 for copper ((r_{cu})), and 0.7 for stainless steel ((r_{304})), ensuring reliable detection regardless of the target material.

Electronically, this sensor offers stable operation. It functions within a 5 - 30 V DC voltage range, providing flexibility in power supply selection. The switching frequency of 0 - 6000 Hz enables rapid response to object presence, making it suitable for high - speed production lines. With a typical hysteresis of 5%, it effectively reduces signal fluctuations near the detection threshold. Built - in reverse polarity protection safeguards the sensor from incorrect power connections, and the pulsing short - circuit protection ensures its long - term durability. The voltage drop is ≤ 1.5 V, and the operating current ranges from 0 to 100 mA, ensuring efficient power usage.

Constructed to withstand harsh industrial conditions, the NBB2 - 6.5M25 - E2 - V3 has a nickel - plated brass housing and an LCP sensing face. It offers an IP67 degree of protection, making it dust - tight and resistant to water immersion. This sensor can operate in ambient temperatures ranging from - 40 °C to + 85 °C (- 40 °F to + 185 °F), and it can be stored within the same temperature range. The connection type is a 3 - pin M8 x 1 connector plug, which is both reliable and easy to install. With these features, it is well - suited for use in a wide variety of industrial settings.
