Inductive sensor M12 for welding process 50 mm cable 2m PNP NO Sn = 4 mm

The professional-grade NWI12013 inductive sensor for welding was designed for applications that demand maximum reliability, interference resistance, and long-term durability.

The M12 format provides solid mechanical mounting while keeping the housing dimensions compact, Ø12 x 50 mm is a format well matched to the typical mounting brackets used at welding stations.

Technical specification:

• Diameter: M12, a versatile size used on most resistance-welding lines
• Length: 50 mm, a short length that makes mounting easier in densely packed welding stations
• Detection range: 4 mm, repeatable detection of metal parts regardless of the interference generated during welding
• Housing: Threaded, a threaded housing allows precise adjustment of the sensor's position relative to the weld point
• Housing material: Brass with PTFE coating, the PTFE coating increases the housing's resistance to the contamination typical of a welding environment
• Sensor face material: PTFE, the PTFE material keeps detection parameters stable even after repeated contact with spatter
• Mounting: Non-flush mounting, non-flush mounting provides a longer detection range when adequate mounting space is available
• Switching function: normally open (NO), standard normally-open logic, compatible with the typical PLC controllers used on welding lines
• Output type: PNP, the PNP output type simplifies integration with the safety modules of resistance-welding robots
• Connection: with a 2 m cable, a cable of suitable length makes it easy to route the wiring away from the hottest zone of the weld
• Supply voltage: DC 10-30V, a standard voltage range compatible with the power supply of most welding-line control cabinets
• Electromagnetic interference (EMC) resistance: yes, proven resistance to the electromagnetic interference generated by resistance-welding machines and welding robots
• Catalog number: W1CN-M1204P-O3U2

Applications

• It supports position control in resistance welding, signaling the machine controller that a part is present in the work zone.
• It is used in welding automation systems and resistance welding automation systems as a feedback element for the PLC controller.
• It is a component of welding process control systems and resistance welding process control systems, confirming the presence and position of parts.
• It is used in automated welding systems and automated resistance welding systems operating continuously.
• It performs well in robotic welding systems and robotic welding lines, where robots operate without constant operator supervision.

Benefits/Features

• As an inductive sensor resistant to electromagnetic interference, it does not generate false triggers during the welding cycle.
• Proven to be resistant to electromagnetic fields, it operates reliably even in the immediate vicinity of the coils and current-carrying cables of a welding machine.
• It is suited to operation in a strong electromagnetic field, typical of resistance welding and arc welding.
• Its proven EMC resistance is valued by integrators building EMC-resistant industrial sensors for welding and resistance-welding applications.
• Thanks to its high resistance, it performs well in environments with high levels of electromagnetic interference, such as those generated by welding machines.

When to choose this model

• If the sensor needs to operate in a welding cell exposed to electromagnetic interference.
• When the resistance-welding process requires non-contact detection of metal parts.
• When stable sensor operation matters despite the interference present in welding processes.
• When you need a reliable solution for welding or resistance-welding automation that provides non-contact detection of metal parts.
