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

The NMF12003-NF inductive sensor is used in machines and production lines where aluminium is the material to be detected, and steel is not a detection target.

The M12 sensor is a reliable solution for control systems requiring resistance to intensive operation and repeatable operating parameters. The Ø12 x 50 mm diameter guarantees a good balance between compact build, mounting stability, and mechanical durability.

Technical specification:

• Diameter: M12, high mechanical resistance of the cylindrical housing guarantees a long service life
• Length: 50 mm, sturdy mechanical design ensures reliable operation in industrial conditions
• Detection range: 2 mm, non-contact detection of metal objects with high repeatability
• 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 full rated range for aluminium makes it easier to design applications without additional assumptions about range reduction
• Housing: Threaded, resistant to loosening during machine operation and vibration
• Housing material: Stainless steel, high resistance to corrosion and chemical exposure
• Sensor face material: Stainless steel, dimensional stability under dynamic load conditions
• Mounting: Flush mounting, mounting into metal surfaces per the flush standard
• Switching function: NO, used in typical machine control applications
• Cable length: 2 m, the cable ensures a highly reliable connection in industrial conditions
• Supply voltage: DC 10-30V, widely used power supply in control systems

Applications

• Quality control in series production – The NF proximity sensor supports quality control and presence checking of aluminium parts during series production.
• Machining fixtures – The non-ferrous metal detector detects the presence of aluminium workpieces in machining fixtures with high repeatability.
• Transport and sorting systems – The inductive sensor for non-ferrous metals performs well in component transport and sorting systems.
• Inspection before stamping – The NF proximity sensor is used to check the presence of a part before the stamping cycle for aluminium sheets and components.
• Multiple processes in one solution – The NF inductive sensor is used where a single solution must handle multiple aluminium-related processes: cutting, stamping, welding, resistance welding, assembly and transport of parts.

Benefits/Features

• K = 1 for aluminium – the K = 1 correction factor allows the rated range to be used for detecting aluminium, without having to account for the typical range reduction applied to this material.
• Detection of a uniform material – the operating characteristics are aimed at detecting the actual part made of aluminium or another non-ferrous metal, not individual particles.
• Distance-to-part inspection – can be used to check the position of an aluminium surface relative to the sensing element.
• For inspecting parts after machining – can be used to detect the actual aluminium workpiece even in environments where machining residue is present.
• Aluminium + non-ferrous metals + K = 1 – the combination of material specialization and full rated range is an important advantage when designing applications.

When to choose this model

• For automatic aluminium inspection – the inductive proximity sensor will work well wherever the presence of an aluminium part in the production process needs to be confirmed.
• For aluminium positioning – choose the part-position sensor when correct alignment of the aluminium part is a precondition for performing the next operation.
• When you need to distinguish the workpiece from fine residue – the part-presence sensor can be a beneficial solution in aluminium machining processes where filings or chips are present.
• 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.
