Inductive sensor M12 metal face 50 mm cable 2m NPN NO Sn = 4 mm NF

The NMF12041-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 M12 sensor is a durable automation component providing effective detection of metal objects and reliable operation. The Ø12 x 50 mm format can be used across a wide range of mounting spaces, from light automation to demanding industrial applications.

Technical specification:

• Diameter: M12, larger active sensing surface ensures effective detection of metal objects
• Length: 50 mm, standard housing length for industrial sensors covering a wide range of applications
• Detection range: 4 mm, stable inductive switching characteristics under industrial conditions
• 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 actual sensing range allows the model to be selected based on the actual distance to the aluminium workpiece
• Housing: Threaded, cylindrical housing with a mounting thread for standard industrial applications
• Housing material: Stainless steel, high resistance to corrosion and chemical exposure
• Sensor face material: Stainless steel, high mechanical resistance to impact, abrasion, and damage
• Mounting: Flush mounting, limited lateral detection field increases operating stability
• Switching function: NO, signal generated during detection of a metal object
• Cable length: 2 m, the absence of a plug-in connector eliminates extra points of potential interference
• 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.
• CNC machines – The NF inductive sensor is used in CNC machines to check the position of aluminium parts and tools.
• Stamping and blanking presses – The aluminium detector is used in presses for stamping and blanking aluminium parts.
• 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.
• 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

• Metal sensing face – the robust metal sensing face performs well in the direct vicinity of machinery, where aluminium parts are detected and individual filings or chips are not the actual detection target.
• No reaction to individual aluminium chips – fine chips are not the actual part that is meant to be detected when inspecting an aluminium workpiece.
• Construction for demanding applications – the full-metal design allows the solution to be used in machines where mechanical resistance and reliable detection of the actual part are important.
• Inspection of the actual workpiece – the solution is designed to detect aluminium and non-ferrous parts, not individual fragments generated during machining.
• 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 aluminium cutting – the sensor for detecting aluminium will work well for checking the presence and position of parts before a cutting operation.
• For automatic assembly stations – the part-detection sensor will work well for checking the presence of aluminium components before assembly.
• When resistance matters during aluminium machining – the full-metal detection element can be a suitable solution for demanding production stations.
• For automatic feeding of aluminium parts – the material-presence sensor will work well for checking a part passing through a specific point in the machine.
