Inductive sensor M18 metal face 79 mm connector M12 PNP NO Sn = 5 mm NF

The NMF18103-NF full-metal inductive sensor provides reliable aluminium detection while maintaining the full, rated operating range.

This M18 model ensures efficient operation in industrial automation installations. Thanks to its diameter, M18 allows easy adaptation to machine structures and industrial equipment.

Technical specification:

• Diameter: M18, reinforced design for operation in harsh conditions and intensive use
• Length: 79 mm, used in large industrial installations requiring high reliability
• Detection range: 5 mm, detection range depending on the diameter and design of the inductive sensor
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), material selectivity makes it possible to disregard fine metal residue that should not be treated as the actual workpiece
• 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, increased mechanical strength of the housing ensures a long service life
• Sensor face material: Stainless steel, increased durability of the sensor's active face under intensive use
• Mounting: Flush mounting, the sensing face is flush with the mounting surface for a safe installation
• Switching function: NO, signal generated during detection of a metal object
• Plug type: M12, connector sensors provide high vibration resistance and signal stability
• Supply voltage: DC 10-30V, stable operation in DC-powered installations

Applications

• Production transport – The NF part-presence sensor monitors the presence of aluminium components in production transport systems.
• Cutting, milling and turning of aluminium – Use in automating aluminium cutting, milling and turning processes increases production efficiency, even when machining chips are present around the workpiece.
• Robotic cells – The NF series detection device is used in robotic cells handling aluminium parts in continuous-cycle operation.
• 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.
• Part presence sensor – can check the presence of an aluminium part at a specific location without having to react to stray material 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.
• Aluminium + non-ferrous metals + K = 1 – the combination of material specialization and full rated range is an important advantage when designing applications.

When to choose this model

• For automating aluminium production processes – the metal sensor can check the position and presence of aluminium components at successive production stages.
• For automatic assembly stations – the part-detection sensor will work well for checking the presence of aluminium components before assembly.
• When you need to distinguish the workpiece from fine residue – the part-presence sensor can be a beneficial solution in aluminium machining processes where filings or chips are present.
• When aluminium must be detected while individual filings and chips are ignored – choose this model for applications where the actual detection target is a solid workpiece, not the fine residue left after its machining.
