Inductive sensor M18 metal face 79 mm connector M12 NPN NO Sn = 5 mm NF

The rugged NMF18101-NF inductive sensor with a metal sensing face has been optimized for detecting aluminium, with a correction factor K = 1.

This M18 model ensures efficient operation in industrial automation installations. M18 sensors offer versatile dimensions suited to typical automation installations, ensuring durability and easy integration.

Technical specification:

• Diameter: M18, increased resistance to shocks and vibration boosts operational reliability
• Length: 79 mm, used in large industrial installations requiring high reliability
• Detection range: 5 mm, stable inductive switching characteristics under industrial conditions
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), detection focused on the actual aluminium part, not on individual filings or chips generated during machining
• 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, resistance to aggressive industrial environments and mechanical damage
• Sensor face material: Stainless steel, resistance to corrosion in humid and chemical environments
• 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
• Plug type: M12, connector sensors allow quick, tool-free connection to industrial installations
• Supply voltage: DC 10-30V, compatible with PLC systems and industrial automation

Applications

• Production transport – The NF part-presence sensor monitors the presence of aluminium components in production transport systems.
• Aluminium packaging – The NF part-presence sensor performs well on packaging lines for aluminium packaging such as cans or foil.
• Aluminium cable production – The inductive proximity sensor supports checking the presence of aluminium conductor or wire during cable production.
• 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.
• Applications with aluminium filings – The non-ferrous metal detector performs well in applications with aluminium filings, where the actual detection target is a larger, solid workpiece, not fine machining residue.

Benefits/Features

• Full-metal construction – the monolithic design, machined from a single piece of metal, provides high mechanical resistance and allows the solution to be used in demanding applications involving the detection of aluminium and non-ferrous metals, where the presence of filings and chips should not affect the inspection of the actual workpiece.
• Part position sensor – enables position checking of an aluminium part within a machine, focusing detection on the actual workpiece.
• Material specialization – the parameters were selected for applications involving aluminium and non-ferrous metals, not for detecting fine metallic contaminants.
• K = 1 + non-ferrous metals – the K = 1 correction factor is an important parameter when designing applications that use non-ferrous materials.
• 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 aluminium stamping – it is worth using for checking the presence of an aluminium sheet, workpiece or part before starting a stamping cycle.
• For automatic assembly stations – the part-detection sensor will work well for checking the presence of aluminium components before assembly.
• When chips should not trigger a detection signal – the model is designed for applications where the actual target is a larger, solid aluminium part.
• For aluminium resistance-welding stations – the proximity sensor can check the presence of a component before the resistance-welding process starts.

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.
