Inductive sensor M12 metal face 68 mm connector M12 PNP NC Sn = 4 mm NF

The specialized NMF12114-NF inductive sensor was developed for precise detection of aluminium components, without reacting to nearby steel parts.

The M12 model belongs to the group of inductive sensors used in automation, process monitoring and metal object presence control. Ø12 x 68 mm sensors offer versatile dimensions suited to typical automation installations, ensuring durability and easy integration.

Technical specification:

• Diameter: M12, larger active sensing surface ensures effective detection of metal objects
• Length: 68 mm, elongated housing with increased mechanical rigidity and high durability
• Detection range: 4 mm, wear resistance thanks to the non-contact metal detection method
• 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 full rated range for aluminium makes it easier to design applications without additional assumptions about range reduction
• Housing: Threaded, allows precise positioning of the sensor during installation
• Housing material: Stainless steel, long sensor lifespan even under intensive use
• Sensor face material: Stainless steel, capable of operating in coolants, oils, and industrial emulsions
• Mounting: Non-flush mounting, wider lateral field of action expands application possibilities
• Switching function: NC, used in safety functions and operational monitoring
• Plug type: M12, connector sensors provide high vibration resistance and signal stability
• Supply voltage: DC 10-30V, compatible with PLC systems and industrial automation

Applications

• Aluminium component production lines – The NF inductive sensor is used on aluminium component production lines to check the presence of parts after machining.
• Inspection before resistance welding – The NF sensor supports automatic position checking of parts before resistance-welding aluminium components at welding stations.
• Electronic enclosures – Use in the production of aluminium electronic enclosures supports automatic assembly control.
• Inspection after cutting – The NF sensor is used to inspect parts after cutting, confirming their correct position on the production line.
• 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

• Specialization for aluminium – the solution was developed for detecting actual aluminium parts, without being aimed at detecting individual filings or chips.
• No reaction to individual aluminium filings – the solution is designed to detect the actual part, so individual aluminium particles are not treated as the intended detection target.
• Part position inspection – enables automatic position checking of a part made of aluminium or another non-ferrous metal.
• For applications with aluminium chips – performs well where fine chips generated during machining should not be treated as the detected part.
• Compact detection setups – the full rated range for aluminium can make it easier to design stations where installation space is limited.

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 aluminium production lines – choose the aluminium sensor when you need automatic checking of part presence and position.
• For applications with aluminium after machining – the model can be used to check the presence of the actual component in an environment where machining residue is 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.
