Inductive sensor M18 metal face 79 mm connector M12 PNP NC Sn = 8 mm NF

The industrial NMF18114-NF inductive sensor in the NF version stands out for its material selectivity - it detects aluminium and non-ferrous metals while ignoring steel and its derivatives.

This M18 model ensures efficient operation in industrial automation installations. M18 sensors fit widely used mounting holes, making replacement and installation upgrades easier.

Technical specification:

• Diameter: M18, increased resistance to shocks and vibration boosts operational reliability
• Length: 79 mm, larger threaded mounting surface provides a more stable fit
• Detection range: 8 mm, repeatable signal activation distance ensures precise detection
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), detection focused on the actual aluminium part, not on individual filings or chips generated during machining
• 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, allows precise positioning of the sensor during installation
• Housing material: Stainless steel, resistance to aggressive industrial environments and mechanical damage
• Sensor face material: Stainless steel, resistance to corrosion in humid and chemical environments
• Mounting: Non-flush mounting, requires maintaining adequate clearance from surrounding metal parts
• Switching function: NC, used in safety functions and operational monitoring
• Plug type: M12, the plug-in design eases servicing and quick sensor replacement
• Supply voltage: DC 10-30V, stable operation in DC-powered installations

Applications

• Vehicle production – Applications of the NF inductive sensor include detecting aluminium parts in automated vehicle production systems.
• Aluminium profiles for windows and doors – The NF full-metal inductive sensor ensures stable operation under the demanding conditions of producing aluminium profiles for windows and doors.
• Stamping and blanking presses – The aluminium detector is used in presses for stamping and blanking aluminium parts.
• Inspection before welding – The inductive sensor for aluminium performs well at welding stations, where it checks the correct position of parts before the process starts.
• Inspection of non-ferrous metal components – Applications of the NF inductive sensor include checking the position of parts made of aluminium and other non-ferrous metals.

Benefits/Features

• Inductive proximity sensor for aluminium – enables non-contact detection of the aluminium part, while individual aluminium filings and chips are not the actual detection target.
• Detection of a uniform material – the operating characteristics are aimed at detecting the actual part made of aluminium or another non-ferrous metal, not individual particles.
• Distance-to-part inspection – can be used to check the position of an aluminium surface relative to the sensing element.
• For inspecting parts after machining – can be used to detect the actual aluminium workpiece even in environments where machining residue is present.
• Comprehensive solution for aluminium detection – the full-metal monolithic construction, metal sensing face, K = 1, actual sensing range and focus on the actual workpiece combine to create a solution for demanding industrial applications.

When to choose this model

• For aluminium detection – choose this model when you need an inductive sensor designed for non-contact detection of aluminium workpieces.
• For aluminium production lines – choose the aluminium sensor when you need automatic checking of part presence and position.
• When resistance matters during aluminium machining – the full-metal detection element can be a suitable solution for demanding production stations.
• For presses and stamping stations – the presence-inspection sensor can confirm the presence of an aluminium workpiece before a working cycle is performed.
