Pepperl+Fuchs NBN4-12GK50-E2 Inductive Proximity Sensor, 12mm Range, M12, PNP NO, IP67 | Industrial Automation

Design and Structure​

The Pepperl + Fuchs NBN4 - 12GK50 - E2 is an inductive sensor with a distinct design. Its 12 - mm diameter cylindrical housing, constructed from durable materials, provides a robust build. The 50 - mm length allows for easy integration into various industrial machinery. It features a non - flush installation type, which positions the sensing face for optimal detection. The sensing face, likely made of a high - quality material such as PBT, is designed to accurately detect metallic objects within a 4 - mm rated sensing distance. This design makes it suitable for applications where precise object detection in a non - concealed setup is essential.​

Electrical Performance​

In terms of electrical specifications, this industrial automation product operates on a DC voltage ranging from 10 - 30 V. It has an NPN output type with a normally open (NO) switching function, enabling seamless control in industrial circuits. The switching frequency can reach up to approximately 1500 Hz, ensuring quick response times to changes in the detected objects. Reverse polarity protection is built - in, safeguarding the sensor from potential damage due to incorrect voltage connections. With a voltage drop of ≤ 3 V and an operating current range of 0 - 200 mA, it can power and interact with different industrial components stably.​

Environmental Adaptability​

The NBN4 - 12GK50 - E2 is engineered to function effectively in diverse environmental conditions. It can withstand an ambient temperature range from - 25 °C to 70 °C (-13 °F to 158 °F), making it suitable for both cold and hot industrial settings. The sensor likely has an IP67 protection rating, which offers high resistance to dust and water immersion. This protection ensures reliable performance even in harsh industrial environments where exposure to moisture and debris is common. The connection is made through a cable, providing flexibility in installation and connection to other parts of the automation system.
