Inductive sensor M12 metal face 68 mm connector M12 PNP NO Sn = 2 mm NF

The NMF12103-NF full-metal inductive sensor stands out for its high mechanical resistance and its ability to disregard individual aluminium filings and chips.

The M12 inductive sensor provides stable operation in control systems and industrial applications exposed to loads. The Ø12 x 68 mm dimensions ensure a stable fit in the structure and resistance to daily use in industrial environments.

Technical specification:

• Diameter: M12, larger active sensing surface ensures effective detection of metal objects
• Length: 68 mm, suited for operation in demanding industrial conditions
• Detection range: 2 mm, detection range depending on the diameter and design of the inductive sensor
• 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 full rated range for aluminium makes it easier to design applications without additional assumptions about range reduction
• Housing: Threaded, fastening with lock nuts ensures a stable installation
• Housing material: Stainless steel, long sensor lifespan even under intensive use
• Sensor face material: Stainless steel, increased durability of the sensor's active face under intensive use
• Mounting: Flush mounting, stable operating characteristics around metal surroundings
• Switching function: NO, normally open resting state, consistent with standard operating logic
• Plug type: M12, the plug-in design eases servicing and quick sensor replacement
• Supply voltage: DC 10-30V, compatible with PLC systems and industrial automation

Applications

• Robotic assembly stations – Use at robotic assembly stations working with aluminium ensures precise detection of the actual workpiece, disregarding individual filings in the surroundings.
• Cutting and preparation of profiles – The inductive sensor for detecting aluminium performs well on cutting and preparation lines for aluminium profiles prior to further processing.
• Scrap recycling and sorting – Use in scrap sorting and non-ferrous metal recycling increases the selectivity of the aluminium recovery process.
• Packaging and labelling – Applications of the NF non-contact sensor include checking the presence of aluminium parts at packaging and labelling stations.
• Automatic metal presence inspection – The metal presence detector is used at production stages where what matters is detecting the entire aluminium workpiece, not individual metallic contaminants.

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 chips – fine chips are not the actual part that is meant to be detected when inspecting an aluminium workpiece.
• Resistant metal sensing face – the metal sensing face provides additional protection when operating near aluminium workpieces, including in environments where chips are present.
• Inspection of the actual workpiece – the solution is designed to detect aluminium and non-ferrous parts, not individual fragments generated during machining.
• 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 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 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 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.
