Inductive sensor M18 metal face 79 mm connector M12 NPN NO Sn = 8 mm FE

The rugged NMF18111-FE inductive sensor with a metal face has been optimised for reliable detection of magnetic objects.

The M18 inductive sensor offers reliable operation in environments with high loads. Thanks to its diameter, M18 allows easy adaptation to machine structures and industrial equipment.

Technical specification:

• Diameter: M18, suited to applications with higher mechanical loads
• Length: 79 mm, elongated housing with increased mechanical rigidity and high durability
• Detection range: 8 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, allows precise positioning of the sensor during installation
• Housing material: Stainless steel, increased mechanical strength of the housing ensures a long service life
• Sensor face material: Stainless steel, high mechanical resistance to impact, abrasion, and damage
• Mounting: Non-flush mounting, wider lateral field of action expands application possibilities
• Switching function: NO, standard operating logic for inductive sensors in industrial automation
• Plug type: M12, connector sensors provide high vibration resistance and signal stability
• Supply voltage: DC 10-30V, compatible with PLC systems and industrial automation

Applications

• Automotive assembly lines – The FE steel detector enables position checking of steel parts on automotive assembly lines, ignoring aluminium components in the surroundings.
• Steel packaging and containers – The FE part-presence sensor performs well on packaging lines for steel packaging and containers, such as drums or metal crates.
• 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.
• Reinforcement bars and construction rods – The FE steel detector performs well on production lines for reinforcement bars and reinforced concrete structural components.

Benefits/Features

• Inductive proximity sensor for steel – enables contactless detection of a steel component, while aluminium components in the surroundings are not the actual detection target.
• 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.
• Material specialisation – the parameters have been selected for applications involving steel and ferrous metals, not for detecting aluminium contaminants.
• Fewer accidental signals – the lack of response to non-ferrous metals can be beneficial in applications where only the presence of the steel component matters.
• Compact detection layouts – the natural, full range for steel can make it easier to design stations where installation space is limited.

When to choose this model

• For automating steel production processes – the metal sensor can check the position and presence of steel components at successive production stages.
• When you need a full-metal construction – choose this model for industrial applications requiring high mechanical resistance.
• When aluminium chips are generated during machining – the solution will perform well in applications where the aim is to detect only the steel part, with aluminium chips completely ignored.
• When steel is to be detected and aluminium completely ignored – choose this model for applications where the actual detection target is exclusively a steel part, regardless of the presence of non-ferrous metals in the surroundings.

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.
