Inductive sensor M12 metal face 50 mm cable 2m PNP NO Sn = 4 mm NF

The NMF12043-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 inductive sensor provides stable operation in control systems and industrial applications exposed to loads. The Ø12 x 50 mm size guarantees mounting stability without taking up excessive space in the device's structure.

Technical specification:

• Diameter: M12, high mechanical resistance of the cylindrical housing guarantees a long service life
• Length: 50 mm, a good balance between size, durability, and mechanical strength
• Detection range: 4 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 correction factor K = 1 means that the rated range Sn applies directly to aluminium, without the typical reduction applied to non-ferrous metals
• Housing: Threaded, a standard solution used in industrial automation and control systems
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, increased durability of the sensor's active face under intensive use
• Mounting: Flush mounting, the sensing face is flush with the mounting surface for a safe installation
• Switching function: NO, output activated upon detecting a metal object
• 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

• Robotic assembly stations – Use at robotic assembly stations working with aluminium ensures precise detection of the actual workpiece, disregarding individual filings in the surroundings.
• Machining fixtures – The non-ferrous metal detector detects the presence of aluminium workpieces in machining fixtures with high repeatability.
• Automatic parts feeding – Use in automatic feeding of aluminium parts on production lines increases process flow.
• Packaging and labelling – Applications of the NF non-contact sensor include checking the presence of aluminium parts at packaging and labelling stations.
• Robotization of aluminium processes – The NF inductive sensor supports the robotization of aluminium processes, providing the automation system with information about the presence or position of the part.

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.
• Non-contact aluminium detection – the part can be detected without mechanical contact with its surface, while individual filings and chips are not the actual detection target.
• Construction for demanding applications – the full-metal design allows the solution to be used in machines where mechanical resistance and reliable detection of the actual part are important.
• Inspection of the actual workpiece – the solution is designed to detect aluminium and non-ferrous parts, not individual fragments generated during machining.
• Resistance + selective detection – the solid construction allows operation in a harsh environment, while the detection characteristics focus on the actual aluminium workpiece.

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 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 cutting generates aluminium chips – the solution will work well in applications where the goal is to detect the actual workpiece, not individual chips generated during machining.
• For robotizing aluminium processes – the part-detection sensor can supply the automation system with information about the presence or position of the aluminium workpiece.
