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

The NMF12042-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 version has been developed for standard and demanding industrial automation solutions, ensuring long service life and reliability. Thanks to their size, Ø12 x 50 mm sensors are easy to install, adjust, and service in machines and automation equipment.

Technical specification:

• Diameter: M12, stable operation in harsh industrial conditions and during intensive use
• Length: 50 mm, versatile dimensions for most industrial automation applications
• Detection range: 4 mm, stable inductive switching characteristics under industrial conditions
• 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, 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, mounting into metal surfaces per the flush standard
• Switching function: NC, used in safety functions and operational monitoring
• Cable length: 2 m, cable sensors have a fixed, factory-made electrical connection to the installation
• Supply voltage: DC 10-30V, stable operation in DC-powered installations

Applications

• Production transport – The NF part-presence sensor monitors the presence of aluminium components in production transport systems.
• Machining fixtures – The non-ferrous metal detector detects the presence of aluminium workpieces in machining fixtures with high repeatability.
• Aluminium cable production – The inductive proximity sensor supports checking the presence of aluminium conductor or wire during cable production.
• Inspection before pressing – Applications of the NF sensor include confirming the presence of the actual aluminium part before starting the next pressing stage.
• Inspection of non-ferrous metal components – Applications of the NF inductive sensor include checking the position of parts made of aluminium and other non-ferrous metals.

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.
• Reduction of unwanted signals – disregarding individual filings and chips can reduce unwanted signals in processes where the actual target is a larger, solid aluminium workpiece.
• Operating selectivity – the ability to disregard individual filings and chips allows operation to be focused on the actual aluminium workpiece.
• For inspecting parts after machining – can be used to detect the actual aluminium workpiece even in environments where machining residue is present.
• 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 inspecting parts after cutting – the part-presence sensor will work well for automatically confirming that an aluminium workpiece is in the correct position.
• When installation space is limited – the full rated range for aluminium can make it easier to design a compact detection setup.
• When fine aluminium fragments remain after stamping – choose this model if the system is meant to check the presence of the actual part, not react to individual material residue.
• For inspecting non-ferrous metal components – choose this model when the automation system must detect actual aluminium parts or other non-ferrous workpieces.
