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

The NMF12114-FE full-metal inductive sensor ensures reliable, repeatable detection of steel while completely ignoring non-ferrous metals within its operating zone.

The M12 sensor belongs to solutions designed for modern industry requiring durability, precision and reliability. The standard Ø12 x 68 mm diameter ensures convenient mounting in most industrial applications along with stable, reliable sensor operation.

Technical specification:

• Diameter: M12, stable operation in harsh industrial conditions and during intensive use
• Length: 68 mm, used in large industrial installations requiring high reliability
• Detection range: 4 mm, non-contact detection of metal objects with high repeatability
• Detected materials: Steel and other ferrous metals (aluminium ignored), aluminium and its alloys are not the detection target, which eliminates unwanted signals in mixed-metal processes involving non-ferrous components
• Correction factor K: K = 1 for steel (full, natural sensing range), the actual detection range allows a model to be selected based on the specific distance to the steel part, regardless of the presence of aluminium in the surroundings
• 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, dimensional stability under dynamic load conditions
• Mounting: Non-flush mounting, maximum detection range for metal objects
• Switching function: NC, output closed at rest ensures continuous signal monitoring
• Plug type: M12, the plug-in design eases servicing and quick sensor replacement
• Supply voltage: DC 10-30V, protection against typical supply voltage fluctuations

Applications

• Robotic assembly stations – Use in robotic assembly stations working with steel ensures precise detection of structural steel parts, while ignoring chips and dust from aluminium machining.
• Steel profiles and structures in construction – The FE full-metal inductive sensor ensures stable operation under the demanding conditions of manufacturing steel profiles and structures for the construction industry.
• Automatic feeding of steel components – Use in the automatic feeding of steel components on production lines increases process smoothness.
• Checking before resistance welding on the production line – The use of the part-presence sensor before the resistance welding process allows verification that the steel component is in the correct place.
• Production of fasteners – The FE inductive sensor is used in the production of bolts, nuts and other steel fasteners, confirming their presence in the process.

Benefits/Features

• Specialisation for steel – the solution was developed to detect the actual steel components, without being aimed at detecting aluminium and its alloys.
• Part-presence sensor – can check the presence of a steel component at a specific location without reacting to incidental aluminium parts.
• Selectivity of operation – the ability to ignore aluminium, brass and copper allows operation to be focused on the actual steel part.
• Fewer accidental signals – the lack of response to non-ferrous metals can be beneficial in applications where only the presence of the steel component matters.
• Detection without aluminium as the actual target – the solution is designed to check a single steel component, not to detect aluminium residue from machining.

When to choose this model

• For detecting steel – choose this model when you need an inductive sensor designed for the contactless detection of steel parts.
• When steel detection should take place with a full, natural range – K=1 makes it easier to select the right variant for the required distance to the part.
• When aluminium should not trigger a detection signal – the model is designed for applications where the actual object is exclusively a steel component.
• For checking ferrous components in a mixed-metal environment – choose this model when the automation system must detect the actual steel components, ignoring aluminium parts present in the same surroundings.
