Inductive sensor M12 metal face 68 mm connector M12 NPN NC Sn = 4 mm NF

The NMF12112-NF inductive sensor supports the control of aluminium production processes, ensuring stable and repeatable detection of the actual workpiece.

The M12 model has been designed to operate in industrial environments requiring high resistance and stable parameters. The Ø12 x 68 mm dimensions provide adequate room for position adjustment as well as secure fastening during machine operation.

Technical specification:

• Diameter: M12, stable operation in harsh industrial conditions and during intensive use
• Length: 68 mm, elongated housing with increased mechanical rigidity and high durability
• Detection range: 4 mm, repeatable signal activation distance ensures precise detection
• 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, allows precise positioning of the sensor during installation
• Housing material: Stainless steel, increased mechanical strength of the housing ensures a long service life
• Sensor face material: Stainless steel, dimensional stability under dynamic load conditions
• Mounting: Non-flush mounting, fully exposed detection zone provides maximum sensing range
• Switching function: NC, output disconnects upon detecting a metal object
• Plug type: M12, the plug-in design eases servicing and quick sensor replacement
• Supply voltage: DC 10-30V, widely used power supply in control systems

Applications

• Vehicle production – Applications of the NF inductive sensor include detecting aluminium parts in automated vehicle production systems.
• Aluminium wheel rims – The inductive sensor for aluminium is used on aluminium wheel rim production lines to check the presence and position of the part.
• Anodizing and surface treatment – Used to check the position of aluminium profiles on anodizing and surface treatment lines.
• Inspection before welding – The inductive sensor for aluminium performs well at welding stations, where it checks the correct position of parts before the process starts.
• Positioning of aluminium parts – The NF inductive sensor supports the positioning of aluminium parts when correct part alignment is a precondition for the next operation.

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.
• 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.
• Mechanical resistance – the full-metal design performs well in applications where aluminium detection takes place in a demanding industrial environment.
• For inspecting parts after machining – can be used to detect the actual aluminium workpiece even in environments where machining residue is present.
• Comprehensive solution for aluminium detection – the full-metal monolithic construction, metal sensing face, K = 1, actual sensing range and focus on the actual workpiece combine to create a solution for demanding industrial applications.

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 position inspection of non-ferrous parts – the model will work well in applications using aluminium and other non-ferrous metals.
• 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 presses and stamping stations – the presence-inspection sensor can confirm the presence of an aluminium workpiece before a working cycle is performed.

Connection

The sensor has an NPN output, so connect it with an M12 4-pin connection cable without LEDs. Cables with LEDs (NXOC12281…, NXOC12401…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
