Inductive sensor M12 metal face 68 mm connector M12 NPN NO Sn = 2 mm NF

The industrial NMF12101-NF inductive sensor in the NF version stands out for its material selectivity - it detects aluminium and non-ferrous metals while ignoring steel and its derivatives.

The M12 inductive sensor is a universal industrial automation component providing precise detection, high durability and stable operation in many applications. The Ø12 x 68 mm diameter guarantees a good balance between compact build, mounting stability, and mechanical durability.

Technical specification:

• Diameter: M12, standard size for most machine applications and industrial automation systems
• 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: Aluminium and other non-ferrous metals (steel ignored), material selectivity makes it possible to disregard fine metal residue that should not be treated as the actual workpiece
• 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, a standard solution used in industrial automation and control systems
• Housing material: Stainless steel, long sensor lifespan even under intensive use
• Sensor face material: Stainless steel, capable of operating in coolants, oils, and industrial emulsions
• Mounting: Flush mounting, stable operating characteristics around metal surroundings
• Switching function: NO, output activated upon detecting a metal object
• Plug type: M12, connector sensors provide high vibration resistance and signal stability
• Supply voltage: DC 10-30V, standard supply voltage range for industrial sensors

Applications

• Automotive assembly lines – The NF aluminium detector enables position control of aluminium parts on automotive assembly lines.
• CNC machines – The NF inductive sensor is used in CNC machines to check the position of aluminium parts and tools.
• Aerospace industry – The aluminium detector is used in the aerospace industry to check the presence of aluminium components.
• 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.
• 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

• Actual sensing range – the designer can select the model based on the actual distance to the aluminium workpiece, instead of applying additional assumptions about range reduction.
• No reaction to individual aluminium filings – the solution is designed to detect the actual part, so individual aluminium particles are not treated as the intended detection target.
• Durable construction – the monolithic construction increases the resistance of the solution used to inspect aluminium parts and other non-ferrous metals.
• K = 1 + actual range – the combination of these parameters makes it easier for the designer to determine the required distance to the aluminium workpiece.
• Solution for industrial automation – the combination of full-metal construction, K = 1 and specialization for aluminium makes the series suitable for demanding automation applications.

When to choose this model

• For inspecting parts before stamping – the inductive proximity sensor makes it possible to check the presence of an aluminium part before the press starts operating.
• When aluminium detection must use the full rated range – K = 1 makes it easier to select the appropriate variant for the required distance to the workpiece.
• 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 inspecting non-ferrous metal components – choose this model when the automation system must detect actual aluminium parts or other non-ferrous workpieces.

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.
