Inductive sensor M18 metal face 79 mm connector M12 PNP NO Sn = 5 mm FE

The professional NMF18103-FE inductive sensor performs well in demanding applications where precise detection of the actual steel part is essential.

The M18 sensor is part of a product range for applications in production systems. The M18 size guarantees mounting stability without taking up excessive space in the device's structure.

Technical specification:

• Diameter: M18, used in heavier industrial automation requiring high durability
• Length: 79 mm, suited for operation in demanding industrial conditions
• Detection range: 5 mm, wear resistance thanks to the non-contact metal detection method
• Detected materials: Steel and other ferrous metals (aluminium ignored), material selectivity allows aluminium, brass, copper and other non-ferrous metals present in the detection zone to be completely ignored
• Correction factor K: K = 1 for steel (full, natural sensing range), the full rated range for steel makes it easier to design applications without additional assumptions about range reduction
• Housing: Threaded, cylindrical housing with a mounting thread for standard industrial applications
• Housing material: Stainless steel, high resistance to corrosion and chemical exposure
• 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, normally open resting state, consistent with standard operating logic
• Plug type: M12, the plug-in connection reduces the risk of installation errors
• Supply voltage: DC 10-30V, standard supply voltage range for industrial sensors

Applications

• Vehicle production – Applications of the FE inductive sensor include the detection of steel components in automated vehicle production systems.
• Robots welding steel structures – Applications of the FE proximity sensor include checking the presence of components in robots welding steel structures.
• Transport and sorting systems – The inductive sensor for ferrous metals performs well in transport and sorting systems for steel components.
• Checking before resistance welding on the production line – The use of the part-presence sensor before the resistance welding process allows verification that the steel component is in the correct place.
• Checking after machining – Applications of the FE proximity sensor include checking steel components after machining, even in an environment containing small aluminium fragments.

Benefits/Features

• Monolithic build – manufacture from a single piece of metal increases the durability of the solution designed for industrial detection of steel and other ferrous metals.
• Stable checking of the actual component – detection focused on steel allows the solution's operation to be better matched to applications in a mixed-metal environment containing non-ferrous metals.
• Distance checking to the part – can be used to check the position of a steel surface relative to the sensing element.
• K=1 + resistance to aluminium – combining the natural K=1 correction factor for steel with total insensitivity to aluminium is an important parameter when designing mixed-metal applications.
• Steel + ferrous metals + K=1 – the combination of material specialisation and full, natural range is an important advantage when designing applications.

When to choose this model

• For steel stamping – it is worth using it to check the presence of a steel sheet, part or component before starting the stamping cycle.
• When installation space is limited – the full, natural range for steel can make it easier to design a compact detection layout.
• When aluminium contamination is present at the station – the steel detection sensor can be used to check the actual part without risk of false triggering from aluminium.
• For robotising steel processes – the part-detection sensor can provide the automation system with information about the presence or position of the steel part.
