Precise Detection Attributes
The Pepperl + Fuchs NBB2 - 8GM25 - E2 - V3 is an inductive proximity sensor engineered for exact object detection. With a rated operating distance of 2 mm, it can accurately sense metallic objects in industrial applications. Its assured operating distance ranges from 0 to 1.62 mm, ensuring consistent performance. The sensor has reduction factors for various metals, like 0.4 for aluminum (
), 0.3 for copper (
), and 0.75 for stainless steel (
). This allows for reliable detection regardless of the target material, making it suitable for diverse industrial setups where precision is crucial.
Stable Electrical Performance
In terms of electricals, this sensor offers stable operation. It functions within a 5 - 30 V DC voltage range, providing flexibility in power supply selection across different industrial environments. The switching frequency of 0 - 6000 Hz enables rapid response to object presence, which is vital for high - speed production lines. A typical hysteresis of 5% helps reduce signal fluctuations near the detection threshold. Built - in reverse polarity protection guards against incorrect power connections, and pulsing short - circuit protection ensures long - term durability. The voltage drop is ≤ 1.5 V, and the operating current ranges from 0 to 100 mA, ensuring efficient power usage.
Durable and Resilient Design
Constructed to endure harsh industrial conditions, the NBB2 - 8GM25 - E2 - V3 features a nickel - plated brass housing and an LCP sensing face. It has an IP67 degree of protection, making it dust - tight and resistant to water immersion. This means it can operate smoothly in environments with dust, moisture, or even in areas where it might be exposed to water splashes. The sensor can function in ambient temperatures ranging from - 40 °C to + 85 °C (- 40 °F to + 185 °F), making it suitable for use in extreme cold or hot industrial settings. The connection type is a 3 - pin M8 x 1 connector plug, which is both reliable and easy to install.
