Inductive sensor M12 metal face 50 mm cable 2m PNP NC Sn = 4 mm NF

The NMF12044-NF full-metal inductive sensor provides the full rated sensing range for aluminium (K = 1), without the typical range reduction applied to non-ferrous metals.

The M12 model provides effective detection and stable operation in production installations and control systems. The Ø12 x 50 mm format allows quick adaptation to standard mounting brackets and a wide range of industrial applications.

Technical specification:

• Diameter: M12, stable operation in harsh industrial conditions and during intensive use
• Length: 50 mm, easy integration with mounting systems and machine structures
• Detection range: 4 mm, wear resistance thanks to the non-contact metal detection method
• 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 actual sensing range allows the model to be selected based on the actual distance to the aluminium workpiece
• Housing: Threaded, resistant to loosening during machine operation and vibration
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, resistance to corrosion in humid and chemical environments
• Mounting: Flush mounting, limited lateral detection field increases operating stability
• Switching function: NC, output closed at rest ensures continuous signal monitoring
• Cable length: 2 m, cable sensors are used where a durable, sealed, non-detachable connection is required
• Supply voltage: DC 10-30V, standard supply voltage range for industrial sensors

Applications

• Aluminium component production lines – The NF inductive sensor is used on aluminium component production lines to check the presence of parts after machining.
• 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.
• Stamping and blanking presses – The aluminium detector is used in presses for stamping and blanking aluminium parts.
• Inspection before resistance welding on the production line – Using the part-presence sensor before the resistance-welding process makes it possible to verify that the aluminium component is in the correct position.
• Applications with aluminium filings – The non-ferrous metal detector performs well in applications with aluminium filings, where the actual detection target is a larger, solid workpiece, not fine machining residue.

Benefits/Features

• Full rated range for aluminium – the range specified in the documentation reflects the actual detection capability, which makes it easier to design applications involving aluminium parts.
• Selective part detection – the solution allows inspection to be focused on the actual aluminium part, reducing the significance of individual filings and chips present around it.
• Distance-to-part inspection – can be used to check the position of an aluminium surface relative to the sensing element.
• Full range + aluminium – K = 1 allows the rated range to be applied directly to the detection of the aluminium part.
• 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 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 you don't need a contaminant detector – choose this model if the device's task is to detect the actual aluminium part, not to check for metallic contaminants.
• For demanding industrial applications – the full-metal inductive sensor will be a suitable choice when, besides aluminium detection, construction durability is important.
