Inductive sensor M12 metal face 68 mm connector M12 NPN NC Sn = 2 mm NF

The modern NMF12102-NF inductive sensor, with its all-metal construction, ensures a long service life when operating in the direct vicinity of aluminium workpieces.

The M12 housing model has been designed for modern detection systems used in machines, production lines and industrial automation. Ø12 x 68 mm sensors work well in standard mounting configurations that require durability and reliable detection.

Technical specification:

• Diameter: M12, standard size for most machine applications and industrial automation systems
• Length: 68 mm, used in large industrial installations requiring high reliability
• Detection range: 2 mm, repeatable signal activation distance ensures precise detection
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), steel and its derivatives are not a detection target, which reduces the number of unwanted signals in aluminium processes
• 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, a standard solution used in industrial automation and control systems
• Housing material: Stainless steel, high resistance to corrosion and chemical exposure
• Sensor face material: Stainless steel, resistance to corrosion in humid and chemical environments
• Mounting: Flush mounting, reduced sensitivity to mechanical damage during use
• Switching function: NC, constant signal monitoring within the control system
• 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

• Stamping and pressing of sheet metal – Using the inductive proximity sensor supports automation of stamping and pressing processes for aluminium sheet metal.
• 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.
• Bicycle frames and components – The NF full-metal inductive sensor performs well on production lines for aluminium bicycle frames and components.
• Machining stations with filings – The metal presence detector supports automatic inspection of aluminium parts at machining stations, where individual filings should not affect the detection result.
• Compact detection setups – The compact design of the NF sensor makes it easier to design aluminium detection stations in locations with limited installation space.

Benefits/Features

• Full-metal construction – the monolithic design, machined from a single piece of metal, provides high mechanical resistance and allows the solution to be used in demanding applications involving the detection of aluminium and non-ferrous metals, where the presence of filings and chips should not affect the inspection of the actual workpiece.
• Non-contact aluminium detection – the part can be detected without mechanical contact with its surface, while individual filings and chips are not the actual detection target.
• Distance-to-part inspection – can be used to check the position of an aluminium surface relative to the sensing element.
• For applications with aluminium filings – can be a beneficial solution where individual filings occur near the actual workpiece and should not be the subject of inspection.
• Solution for industrial automation – the combination of full-metal construction, K = 1 and specialization for aluminium makes the series suitable for demanding automation applications.

When to choose this model

• For machining aluminium – choose this model when you need to check part presence at an automatic machining station.
• When aluminium is the main detection material – this aluminium sensor will be a better choice than a solution selected purely as a universal metal sensor.
• When chips should not trigger a detection signal – the model is designed for applications where the actual target is a larger, solid aluminium 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.

Connection

The sensor has an NPN output, so connect it with an M12 4-pin connection cable without LEDs. Cables with LEDs (NXOC12281…, NXOC12401…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
