Product Overview
The P+Fuchs NBN40-U1-A2 Inductive Sensor is a high-performance, non-contact proximity switch engineered for reliable position detection and presence sensing of metallic targets in industrial automation systems. Manufactured by P+Fuchs under the renowned VariKont series, this rectangular inductive sensor offers a long non-flush sensing range of 40 mm. Its innovative rotatable sensor head can be positioned in five distinct orientations, providing outstanding mechanical flexibility during installation in compact machinery and tight mounting spaces.
Constructed with a rugged PA (polyamide) housing and a durable PA sensing face, the NBN40-U1-A2 is equipped with an IP68 and IP69K environmental ingress protection rating to withstand high-pressure washdowns, aggressive cutting fluids, and heavy industrial grime. It operates on a 10 to 30 VDC supply voltage and features a complementary 4-wire DC PNP output (selectable normally open and normally closed functions). Dual LED status indicators provide immediate visual feedback of power and switching status, making it a dependable choice for automotive assembly, material handling, packaging machinery, and process manufacturing.

How do I find the right part for my system?
Three options. Search by part number if you have the OEM code from Parker, Danfoss, Linde, Kawasaki, Kayaba or Grundfos — our search recognises both manufacturer codes and aftermarket cross-references. Browse by category if you know the component type (pumps, valves, cylinders, etc.). Or send a spec sheet to our engineering desk and we'll cross-reference against our 3,000+ SKU catalogue within one business day.
Can you help me size a pump or valve for my application?
Yes — sizing support is included with every order. Send us your operating pressure, flow rate, viscosity, drive speed and duty cycle, and our engineers will recommend a suitable component from our catalogue with full datasheets. We don't custom-build parts ourselves, but we can spec the right OEM component for almost any standard industrial application.
Can you cross-reference a discontinued part?
Yes — cross-referencing is one of the things we do most. Send us the original part number (even if the manufacturer has dropped it) and our engineering desk will identify a current equivalent or compatible alternative. Cross-reference lookups are free and typically come back within 4 business hours.
