Pepperl+Fuchs Automation is our world. Perfect application solutions are our goal.

In 1945, against the backdrop of a war - torn world, Walter Pepperl and Ludwig Fuchs, driven by a strong sense of inventiveness, entrepreneurial foresight, and a deep - seated belief in self - reliance, established a humble radio workshop in Mannheim, Germany.

Their journey was filled with hands - on exploration. As they worked on various radio - related projects, the experiences they amassed became the fertile ground for new and innovative concepts. They took great pleasure in delving into the needs of their customers, constantly striving to develop products that could meet and exceed expectations.

I’ve used this M12 sensor-actuator cable across 3 automotive assembly lines for 18 months, and it’s been flawless. The PUR jacket handles constant oil, coolant, and heavy robotic bending without cracking or hardening. 5m length is perfect for most cell layouts—no excess slack or tension. M12 connectors click in solid, gold-plated contacts stay corrosion-free, and IP67/IP69K sealing stands up to high-pressure washdowns. Zero signal drops, zero unplanned downtime. Worth every penny over generic cables. Highly recommend for harsh industrial environments.

We’ve installed the NBN3-F31K-Z8-K on our pneumatic actuator stations for over a year, and it’s been totally reliable. The 3 mm sensing range is spot-on for detecting small metal targets, with consistent accuracy and almost no hysteresis. Its IP67-rated PBT housing handles oil, dust and occasional water splashes without issues—ideal for our factory floor. The sensor’s compact block design mounts directly to standard actuators, saving time and brackets. Two yellow LEDs clearly show sensor and valve status, making troubleshooting a breeze. With 6–60 V DC wide voltage input, 500 Hz switching frequency, and -25°C to 70°C working range, it fits most industrial setups. Reverse polarity protection is a nice safety touch. A solid, well-built sensor worth the investment.
