Inductive sensor M18 metal face 48 mm connector M12 PNP NO Sn = 5 mm FE

The NMF18123-FE full-metal inductive sensor is designed for selective detection of steel and ferromagnetic materials, while completely ignoring aluminium components and other non-ferrous metals.

This M18 variant is a solution for industry where durability and reliability are essential. M18 sensors allow comfortable installation in typical working conditions as well as more demanding industrial environments.

Technical specification:

• Diameter: M18, used in heavier industrial automation requiring high durability
• Length: 48 mm, versatile dimensions for most industrial automation applications
• Detection range: 5 mm, repeatable signal activation distance ensures precise detection
• 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 actual detection range allows a model to be selected based on the specific distance to the steel part, regardless of the presence of aluminium in the surroundings
• Housing: Threaded, allows precise positioning of the sensor during installation
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, high mechanical resistance to impact, abrasion, and damage
• Mounting: Flush mounting, the sensing face is flush with the mounting surface for a safe installation
• Switching function: NO, standard operating logic for inductive sensors in industrial automation
• Plug type: M12, the plug-in design eases servicing and quick sensor replacement
• Supply voltage: DC 10-30V, protection against typical supply voltage fluctuations

Applications

• Robotic assembly stations – Use in robotic assembly stations working with steel ensures precise detection of structural steel parts, while ignoring chips and dust from aluminium machining.
• 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.
• Assembly of steel building structures – The FE inductive sensor supports the automation of steel structure assembly processes in the construction industry.
• Checking after steel cutting – The FE sensor is used to check parts after cutting, confirming their correct position on the production line.
• Multiple processes in a single solution – The FE inductive sensor is used wherever a single solution must handle multiple steel-related processes: cutting, stamping, welding, resistance welding, assembly and transport of components.

Benefits/Features

• Metal sensing face – the resistant metal sensing face performs well in the immediate vicinity of machines where steel components are detected, and individual aluminium contaminants do not constitute the actual detection target.
• Material detection, not contaminant detection – the solution is used to check the presence of the actual steel material, not to detect aluminium metallic contaminants.
• Selectivity of operation – the ability to ignore aluminium, brass and copper allows operation to be focused on the actual steel part.
• 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.
• Contactless material checking – the solution enables automatic detection of steel components without physical contact with the part and without being aimed at aluminium contaminants.

When to choose this model

• For checking components before resistance welding – the contactless sensor enables checking the presence of a part without mechanical contact with its surface.
• For positioning steel components – choose the part-position sensor when the correct placement of the steel component is a precondition for the next operation.
• For applications with steel after machining – the model can be used to check the presence of the actual component even in an environment where aluminium residue from machining is present.
• 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.
