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

The NMF18113-FE full-metal inductive sensor ensures reliable, repeatable detection of steel while completely ignoring non-ferrous metals within its operating zone.

The M18 sensor is part of a product range for applications in production systems. M18 sensors provide adequate working clearance around the target as well as stable operation in detection systems.

Technical specification:

• Diameter: M18, increased resistance to shocks and vibration boosts operational reliability
• Length: 79 mm, better resistance to shocks, vibration, and mechanical stress
• Detection range: 8 mm, stable inductive switching characteristics under industrial conditions
• 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, cylindrical housing with a mounting thread for standard industrial applications
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, dimensional stability under dynamic load conditions
• Mounting: Non-flush mounting, requires maintaining adequate clearance from surrounding metal parts
• Switching function: NO, standard operating logic for inductive sensors in industrial automation
• Plug type: M12, the plug-in connection reduces the risk of installation errors
• Supply voltage: DC 10-30V, stable operation in DC-powered installations

Applications

• Quality control in serial production – The FE proximity sensor supports the selective checking of the presence of ferromagnetic components in mixed technological assemblies.
• CNC machines – The FE inductive sensor is used in CNC machines to check the position of steel components and tools, ignoring aluminium guards and components in the surroundings.
• Robotic cells – The FE series detection device is used in robotic cells handling steel parts in continuous cycle operation.
• Checking before stamping of steel sheets – The FE proximity sensor is used to check the presence of a part before the stamping cycle of steel sheets and components.
• Production of fasteners – The FE inductive sensor is used in the production of bolts, nuts and other steel fasteners, confirming their presence in the process.

Benefits/Features

• Actual detection range – designers can select a model based on the specific distance to the steel part, without having to account for additional correction factors.
• 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.
• Durable construction – the monolithic construction increases the resistance of the solution used to check steel components.
• For checking components after machining – can be used to detect the actual steel part even in an environment where aluminium residue from machining is present.
• Steel component position sensor – can check the position of a part in a machine, while aluminium components in the surroundings are not the actual detection target.

When to choose this model

• For steel machining – choose this model when you need to check the presence of a part at an automatic machining station.
• When you need a full-metal construction – choose this model for industrial applications requiring high mechanical resistance.
• 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 steel welding stations – contactless position checking allows verification that the component is in the correct place before the operation begins.
