The Pepperl + Fuchs NBN40-U1-A2 is a high-performance inductive proximity switch sensor designed to offer reliable and precise detection of metallic objects without any physical contact. This sensor is engineered to operate within a 10 to 30 VDC range and is equipped with a 4-pin connector, ensuring easy integration into various industrial applications.
With a nominal operating distance of 40 mm and a non-flush installation design, this sensor provides a robust sensing solution in environments where direct contact with the target is not possible or desirable. The device features a PNP output and offers both normally open (NO) and normally closed (NC) configurations, enhancing its versatility for different control logic requirements.
The sensor is built to withstand harsh industrial conditions, boasting an IP68/IP69K protection rating, which ensures it is dust-tight and can resist high-pressure water jets. Its durable housing is made from a combination of PA and metal with an epoxy powder coating, and the sensing face is constructed from PA, contributing to its longevity and resilience.
This inductive proximity switch sensor is also equipped with LED indicators for 360° visibility of the operating status, which aids in quick diagnostics and monitoring. The device's technical specifications include a switching frequency of up to 180 Hz, a typical hysteresis of 5%, and short-circuit protection with pulsing, ensuring reliable operation and protection against electrical disturbances.
The Pepperl + Fuchs NBN40-U1-A2 is compliant with relevant EN and IEC standards, reflecting its adherence to quality and safety benchmarks. It is suitable for a wide range of industrial applications, including machinery positioning, presence detection, and automation tasks where precision and reliability are paramount.

Absolutely fantastic service. Rob was very helpful. Great communication. Requested part was shipped in no time.Konrad Eliaszuk
Found the component i was looking for ad a great price. Great support from the staff as I was paying using a wire transfer. - Quick delivery and very good packaging.Adriano Tiberi
Found the part we needed at the best price. Spoke to Rob to make sure the part was actually in stock, as many companies don't actually have the part available to ship. It was in stock ready and the part was checked and shipped and received within a couple of days from their German stock. Would definitely use again and recommend.Chris Sentance
FIRST TIME WORKING WITH MARVO. THEY HAD WHAT I NEEDED AND TOOK GREAT CARE OF ME AND GOT MY ORDER OUT IMMEDITELY. WAS VERY IMPRESSED WITH THE SERVICE AND THE PERSON I SPOKE WITH. I WILL DEFINITELY WORK WITH THEM QGAIN IN THE FUTURE.Robert Cohen

Thumbs up to Rob for helping out with an urgent requirement we had on a Friday afternoon. The part we wanted was over in Europe and Rob went out of his way to get it ordered and on site here for the following Tuesday.City Bearings
Extremely Helpful. Shipped me a replacement unit next day and i was up and running within 24 hours. Replacement new from machinery manufacturers was on a 7 day lead time.Sean Conlin
