Inductive sensor M12 metal face 68 mm connector M12 PNP NO Sn = 4 mm NF

The rugged NMF12143-NF inductive sensor with a metal sensing face has been optimized for detecting aluminium, with a correction factor K = 1.

This M12 model is designed for applications requiring durability, resistance to interference and high repeatability of operation. Ø12 x 68 mm sensors provide adequate working clearance around the target as well as stable operation in detection systems.

Technical specification:

• Diameter: M12, larger active sensing surface ensures effective detection of metal objects
• Length: 68 mm, better resistance to shocks, vibration, and mechanical stress
• Detection range: 4 mm, repeatable signal activation distance ensures precise detection
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), detection focused on the actual aluminium part, not on individual filings or chips generated during machining
• Correction factor K: K = 1 for aluminium (full rated sensing range), the full rated range for aluminium makes it easier to design applications without additional assumptions about range reduction
• Housing: Threaded, resistant to loosening during machine operation and vibration
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, increased durability of the sensor's active face under intensive use
• Mounting: Flush mounting, reduced sensitivity to mechanical damage during use
• Switching function: NO, used in typical machine control applications
• Plug type: M12, connector sensors allow quick, tool-free connection to industrial installations
• Supply voltage: DC 10-30V, compatible with PLC systems and industrial automation

Applications

• Positioning of aluminium profiles – Using the part-position sensor in aluminium profile positioning systems increases the reliability of industrial automation processes.
• CNC machines – The NF inductive sensor is used in CNC machines to check the position of aluminium parts and tools.
• Transport and sorting systems – The inductive sensor for non-ferrous metals performs well in component transport and sorting systems.
• Packaging and labelling – Applications of the NF non-contact sensor include checking the presence of aluminium parts at packaging and labelling stations.
• Applications with aluminium filings – The non-ferrous metal detector performs well in applications with aluminium filings, where the actual detection target is a larger, solid workpiece, not fine machining residue.

Benefits/Features

• Monolithic build – being machined from a single piece of metal increases the durability of the solution intended for industrial detection of aluminium and other non-ferrous metals.
• Stable inspection of the actual part – detection focused on the actual material allows the solution's operation to be better matched to applications involving aluminium and non-ferrous metals.
• Part position inspection – enables automatic position checking of a part made of aluminium or another non-ferrous metal.
• K = 1 + actual range – the combination of these parameters makes it easier for the designer to determine the required distance to the aluminium workpiece.
• Comprehensive solution for aluminium detection – the full-metal monolithic construction, metal sensing face, K = 1, actual sensing range and focus on the actual workpiece combine to create a solution for demanding industrial applications.

When to choose this model

• For aluminium welding – choose this model for automatic position checking of aluminium parts during preparation and operation of welding stations.
• When aluminium detection must use the full rated range – K = 1 makes it easier to select the appropriate variant for the required distance to the workpiece.
• When you want to inspect the actual part instead of production waste – choose a solution designed to detect the aluminium workpiece, not fine fragments generated during machining.
• For automatic feeding of aluminium parts – the material-presence sensor will work well for checking a part passing through a specific point in the machine.
