Inductive sensor M18 metal face 55 mm cable 2m PNP NC Sn = 5 mm NF

The NMF18004-NF inductive sensor is an industrial-grade solution designed for detecting aluminium workpieces, where individual filings and chips should not trigger a detection signal.

The M18 product has been designed for automation systems with high operational requirements. The versatile M18 size makes integration easier across many machine designs, control systems, and industrial installations.

Technical specification:

• Diameter: M18, reinforced design for operation in harsh conditions and intensive use
• Length: 55 mm, suited for operation in demanding industrial conditions
• Detection range: 5 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, resistant to loosening during machine operation and vibration
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, capable of operating in coolants, oils, and industrial emulsions
• Mounting: Flush mounting, limited lateral detection field increases operating stability
• Switching function: NC, signal continuity monitoring increases system reliability
• Cable length: 2 m, the absence of a plug-in connector eliminates extra points of potential interference
• Supply voltage: DC 10-30V, standard supply voltage range for industrial sensors

Applications

• Automotive assembly lines – The NF aluminium detector enables position control of aluminium parts on automotive assembly lines.
• CNC machines – The NF inductive sensor is used in CNC machines to check the position of aluminium parts and tools.
• Aerospace industry – The aluminium detector is used in the aerospace industry to check the presence of aluminium components.
• Automatic assembly stations – The NF inductive sensor performs well at automatic assembly stations, checking the presence of aluminium components before assembly.
• Positioning of aluminium parts – The NF inductive sensor supports the positioning of aluminium parts when correct part alignment is a precondition for the next operation.

Benefits/Features

• Easier model selection – K = 1 simplifies selecting a solution for applications where aluminium parts are detected and filings should not trigger a detection signal.
• Material detection instead of contaminant detection – the solution is used to check the presence of the actual aluminium or non-ferrous material, not to detect metallic contaminants.
• Proximity sensor for non-ferrous metals – performs well for non-contact inspection of aluminium parts and other non-ferrous metals.
• K = 1 + non-ferrous metals – the K = 1 correction factor is an important parameter when designing applications that use non-ferrous materials.
• Detection excluding filings and chips as the actual target – the solution was designed to inspect a solid aluminium part, not to detect fine machining residue.

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 you need a full-metal construction – choose this model for industrial applications where high mechanical resistance is required.
• When you don't need a contaminant detector – choose this model if the device's task is to detect the actual aluminium part, not to check for metallic contaminants.
• For inspecting non-ferrous metal components – choose this model when the automation system must detect actual aluminium parts or other non-ferrous workpieces.
