Inductive sensor M18 metal face 55 mm cable 2m NPN NO Sn = 8 mm FE

The NMF18011-FE full-metal inductive sensor stands out for its high mechanical resistance and its ability to ignore aluminium chips and dust.

The M18 model represents a sensor line for demanding production applications. M18 sensors provide adequate working clearance around the target as well as stable operation in detection systems.

Technical specification:

• Diameter: M18, suited to applications with higher mechanical loads
• Length: 55 mm, larger threaded mounting surface provides a more stable fit
• Detection range: 8 mm, detection range depending on the diameter and design of the inductive sensor
• 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, resistance to aggressive industrial environments and mechanical damage
• Sensor face material: Stainless steel, resistance to corrosion in humid and chemical environments
• Mounting: Non-flush mounting, requires maintaining adequate clearance from surrounding metal parts
• Switching function: NO, normally open resting state, consistent with standard operating logic
• 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

• Positioning of steel profiles and structures – The use of the part-position sensor in steel profile positioning systems increases the reliability of industrial automation processes.
• Robots welding steel structures – Applications of the FE proximity sensor include checking the presence of components in robots welding steel structures.
• Galvanising and surface treatment of steel – Use in checking the position of steel components on galvanising and surface treatment lines.
• Machining stations with aluminium dust and chips – The metal presence detector supports automatic checking of steel parts at machining stations, where individual aluminium filings and dust do not affect the detection result.
• Applications with aluminium chips in the surroundings – The FE inductive sensor is used in applications where aluminium chips are generated during machining, without being aimed at detecting them.

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.
• No response to aluminium filings – the solution is designed to detect the actual steel component, so aluminium filings are not treated as the target detection object.
• Distance checking to the part – can be used to check the position of a steel surface relative to the sensing element.
• Checking the actual part – the solution is designed to detect steel components, not aluminium fragments or dust present in the surroundings.
• A comprehensive solution for steel detection – the full-metal monolithic construction, metal sensing face, K=1, actual range and focus on the actual part together form a solution for demanding industrial applications.

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.
• When steel detection should take place with a full, natural range – K=1 makes it easier to select the right variant for the required distance to the part.
• When you do not want to react to non-ferrous metals – choose this model if the device's task is to detect only the steel component, not aluminium, brass or copper in the surroundings.
• For robotising steel processes – the part-detection sensor can provide the automation system with information about the presence or position of the steel part.
