Inductive sensor M12 metal face 68 mm connector M12 NPN NO Sn = 2 mm FE

The industrial NMF12101-FE inductive sensor is used in machines and production lines where steel is the object of interest and aluminium does not generate a signal.

This M12 inductive sensor is intended for integration with automation systems, process control systems and industrial equipment. The Ø12 x 68 mm format makes it easy to mount in standard enclosures and industrial automation systems that require reliable components.

Technical specification:

• Diameter: M12, stable operation in harsh industrial conditions and during intensive use
• Length: 68 mm, elongated housing with increased mechanical rigidity and high durability
• Detection range: 2 mm, wear resistance thanks to the non-contact metal detection method
• Detected materials: Steel and other ferrous metals (aluminium ignored), detection focused on the actual steel part, not on individual aluminium filings, chips or dust remaining in the surroundings
• Correction factor K: K = 1 for steel (full, natural sensing range), the K = 1 correction factor applies to steel and other ferrous metals as the reference material, meaning the rated operating distance Sn is the full, natural detection range
• Housing: Threaded, fastening with lock nuts ensures a stable installation
• Housing material: Stainless steel, long sensor lifespan even under intensive use
• Sensor face material: Stainless steel, capable of operating in coolants, oils, and industrial emulsions
• Mounting: Flush mounting, mounting into metal surfaces per the flush standard
• Switching function: NO, signal generated during detection of a metal object
• Plug type: M12, connector sensors allow quick, tool-free connection to industrial installations
• Supply voltage: DC 10-30V, standard supply voltage range for industrial sensors

Applications

• Production transport and intralogistics – The FE part-presence sensor monitors the presence of steel pallets, parts or hooks on conveyor lines and belt conveyors.
• Steel cutting, milling and turning – Use in the automation of steel cutting, milling and turning processes increases production efficiency, even when aluminium fixture or guard components are present around the part.
• Recycling and sorting of steel scrap – Use in scrap sorting and ferrous metal recycling increases the selectivity of the steel recovery process.
• 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.
• Compact detection layouts – The compact design of the FE sensor makes it easier to design steel detection stations in locations with limited installation space.

Benefits/Features

• Specialisation for steel – the solution was developed to detect the actual steel components, without being aimed at detecting aluminium and its alloys.
• Part-presence sensor – can check the presence of a steel component at a specific location without reacting to incidental aluminium parts.
• Mechanical resistance – the full-metal design performs well in applications where steel detection takes place in a demanding industrial environment.
• Range without additional correction for steel – the ability to use the rated range makes it easier to select the right solution for a specific application.
• 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 detecting steel – choose this model when you need an inductive sensor designed for the contactless detection of steel parts.
• When steel is the primary detection material – this sensor for steel will be a better choice than a solution selected purely as a universal metal sensor.
• When the sensor operates close to the machine – the metal sensing face and monolithic construction perform well in locations exposed to contact with the working environment.
• For steel resistance welding stations – the proximity sensor can check the presence of the component before the resistance welding process starts.

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.
