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

The selective NMF12103-FE inductive sensor stands out for its high material selectivity - it detects only steel and ferrous metals, disregarding aluminium and its alloys.

The M12 inductive sensor provides stable operation in control systems and industrial applications exposed to loads. The Ø12 x 68 mm dimensions promote quick installation, easy replacement, and reduced servicing time for equipment.

Technical specification:

• Diameter: M12, high mechanical resistance of the cylindrical housing guarantees a long service life
• Length: 68 mm, suited for operation in demanding industrial conditions
• Detection range: 2 mm, non-contact detection of metal objects with high repeatability
• Detected materials: Steel and other ferrous metals (aluminium ignored), material selectivity allows aluminium, brass, copper and other non-ferrous metals present in the detection zone to be completely ignored
• 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, fastening with lock nuts ensures a stable installation
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, dimensional stability under dynamic load conditions
• Mounting: Flush mounting, reduced sensitivity to mechanical damage during use
• Switching function: NO, signal generated during detection of a metal object
• Plug type: M12, connector sensors provide high vibration resistance and signal stability
• Supply voltage: DC 10-30V, stable operation in DC-powered installations

Applications

• Steel component production lines – The FE inductive sensor is used on steel component production lines, providing precise checking of the presence and position of ferrous parts in an environment containing traces of aluminium.
• Steel structures of heat exchangers – Use in the production of steel components for heat exchangers and radiators increases the reliability of process control.
• Transport and sorting systems – The inductive sensor for ferrous metals performs well in transport and sorting systems for steel components.
• Machining stations with aluminium dust and chips – The metal presence detector supports automatic checking of steel parts at machining stations, where individual aluminium filings and dust do not affect the detection result.
• Applications with aluminium filings in the surroundings – The ferrous metal detector performs well in applications where aluminium filings are present near the steel part and should not affect the detection result.

Benefits/Features

• Inductive proximity sensor for steel – enables contactless detection of a steel component, while aluminium components in the surroundings are not the actual detection target.
• Material detection, not contaminant detection – the solution is used to check the presence of the actual steel material, not to detect aluminium metallic contaminants.
• Part-presence checking – allows detection of the actual steel component in the production process, without being intended to detect aluminium contaminants.
• For applications with aluminium chips in the surroundings – performs well wherever aluminium chips generated during machining should not be treated as the detected element.
• 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 automatic steel checking – the inductive proximity sensor will perform well wherever the presence of a steel component needs to be confirmed in the production process.
• When the actual range matters – choose this model if, when designing an application, you want to base the detection distance on the value given in the documentation.
• When aluminium should not trigger a detection signal – the model is designed for applications where the actual object is exclusively a steel component.
• For steel welding stations – contactless position checking allows verification that the component is in the correct place before the operation begins.
