Product Description
The Pepperl+Fuchs NCB5-18GM40-N0 is an inductive proximity sensor designed with a NAMUR output and a rated sensing distance of 5 mm . It features a stainless steel housing with an M18 threaded cylindrical design, making it suitable for flush mounting in industrial applications . This sensor operates on a 8.2V supply voltage and utilizes a 2-wire, SCR normally closed (NC) output circuit . With a high protection rating of IP67, it is well-protected against dust and temporary immersion in water . The device is designed to function reliably across a broad operating temperature range of -25°C to 100°C . As a NAMUR type sensor, it is intrinsically safe and primarily used for non-contact detection of metal objects in potentially hazardous areas or with control systems requiring this specific output .

Key Features
- NAMUR Output: The 2-wire, SCR-based NAMUR output is a key safety feature. It is intrinsically safe by design, limiting the current and energy in the circuit. This makes the sensor suitable for installation in potentially explosive atmospheres, where it interfaces with a safety barrier or isolated amplifier .
- Robust Construction: Encased in a stainless steel body, the sensor offers high resistance to corrosion, impacts, and harsh chemicals. The IP67 protection rating means it is completely protected against dust and can withstand immersion in water up to 1 meter for 30 minutes, guaranteeing longevity in challenging conditions like wash-down environments .
- Flush Mounting Capability: Being an unshielded sensor, it can be installed flush into a metal bracket or mounting surface without the risk of the sensor interfering with itself. This allows for a very compact and protected installation, saving space and preventing damage from accidental impacts .
- Clear Status Indication: A bright, yellow LED provides 360-degree visibility of the switching status, enabling quick and easy diagnostics from any angle, which simplifies setup and troubleshooting .
