Inductive sensor M8 metal face 60 mm connector M8 NPN NO Sn = 1 mm NF

The NMF08101-NF inductive sensor, in a full-metal design, combines high mechanical resistance with selective detection of aluminium and other non-ferrous metals.

Thanks to their construction, M8 sensors offer installation flexibility in various applications. M8 sensors provide stable operation in confined working spaces. The Ø8 x 60 mm size allows installation in places with limited depth without compromising performance.

Technical specification:

• Diameter: M8, commonly used in industrial automation and process control systems
• Length: 60 mm, used in large industrial installations requiring high reliability
• Detection range: 1 mm, wear resistance thanks to the non-contact metal detection method
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), steel and its derivatives are not a detection target, which reduces the number of unwanted signals in aluminium processes
• Correction factor K: K = 1 for aluminium (full rated sensing range), the correction factor K = 1 means that the rated range Sn applies directly to aluminium, without the typical reduction applied to non-ferrous metals
• Housing: Threaded, a standard solution used in industrial automation and control systems
• Housing material: Stainless steel, high resistance to corrosion and chemical exposure
• Sensor face material: Stainless steel, dimensional stability under dynamic load conditions
• Mounting: Flush mounting, stable operating characteristics around metal surroundings
• Switching function: NO, used in typical machine control applications
• Plug type: M8, the plug-in connection reduces the risk of installation errors
• Supply voltage: DC 10-30V, protection against typical supply voltage fluctuations

Applications

• Vehicle production – Applications of the NF inductive sensor include detecting aluminium parts in automated vehicle production systems.
• Robots welding aluminium structures – Applications of the NF proximity sensor include checking the presence of parts in robots welding aluminium structures.
• Electronic enclosures – Use in the production of aluminium electronic enclosures supports automatic assembly control.
• Inspection before stamping – The NF proximity sensor is used to check the presence of a part before the stamping cycle for aluminium sheets and components.
• Inspection after cutting/machining – Applications of the NF proximity sensor include inspecting parts after machining, even in environments containing fine aluminium fragments.

Benefits/Features

• Specialization for aluminium – the solution was developed for detecting actual aluminium parts, without being aimed at detecting individual filings or chips.
• Reduction of unwanted signals – disregarding individual filings and chips can reduce unwanted signals in processes where the actual target is a larger, solid aluminium workpiece.
• Material specialization – the parameters were selected for applications involving aluminium and non-ferrous metals, not for detecting fine metallic contaminants.
• For inspecting parts after machining – can be used to detect the actual aluminium workpiece even in environments where machining residue is present.
• Non-contact material inspection – the solution enables automatic detection of aluminium parts without physical contact with the workpiece and without being aimed at individual filings.

When to choose this model

• For inspecting parts before resistance welding – the non-contact sensor enables presence checking of a part without mechanical contact with its surface.
• When aluminium detection must use the full rated range – K = 1 makes it easier to select the appropriate variant for the required distance to the workpiece.
• When the process generates aluminium filings – choose this model if the actual detection target is a larger, solid workpiece, and individual filings should not be treated as the actual part.
• When you need a single solution for various aluminium processes – the model can be used for cutting, stamping, welding, resistance welding, assembly and transport of aluminium parts.

Connection

The sensor has an NPN output, so connect it with an M8 3-pin connection cable without LEDs. Cables with LEDs (NXOC08261…, NXOC08121…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
