Inductive sensor M12 for welding process 68 mm connector M12 PNP NO Sn = 4 mm

The NWI12113 welding inductive sensor is an efficient solution for industrial robotics, positioning systems, and advanced control systems used in welding processes.

The M12 sensor works well as a universal solution for most welding and resistance-welding stations, Ø12 x 68 mm is a compact format that does not restrict the freedom of movement of a welding robot.

Technical specification:

• Diameter: M12, a versatile size used on most resistance-welding lines
• Length: 68 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• Detection range: 4 mm, stable metal-detection characteristics even close to a resistance-welding machine's electromagnetic field
• Housing: Threaded, the housing thread allows fine adjustment of the detection distance during installation on the line
• Housing material: Brass with PTFE coating, a PTFE layer on the brass housing reduces weld spatter sticking to the sensor's surface
• Sensor face material: PTFE, a PTFE sensing face prevents metal spatter from welding and resistance welding from sticking
• Mounting: Non-flush mounting, non-flush mounting provides a longer detection range when adequate mounting space is available
• Switching function: normally open (NO), the NO function simplifies integration with most existing resistance-welding machine control systems
• Output type: PNP, a PNP output that is standard for most new welding automation installations
• Connection: with a M12 plug connector, a plug connector allows quick sensor replacement without dismantling the entire welding installation
• Supply voltage: DC 10-30V, a typical industrial automation supply voltage, with no need for additional converters
• Electromagnetic interference (EMC) resistance: yes, EMC resistance allows mounting close to a resistance-welding machine's coils and current-carrying cables without signal loss
• Catalog number: W1CN-M1204P-OEU4

Applications

• It is used in resistance-welding robots as an inductive sensor for resistance-welding robots, operating in the immediate vicinity of the weld point.
• Used on resistance-welding lines and automated resistance welding lines, where cycle repeatability matters most.
• It functions as a position sensor for resistance welding machines and a part-presence sensor for resistance welding, confirming correct part placement before the cycle.
• 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.

Benefits/Features

• A construction resistant to the welding environment and to spatter generated during welding extends the sensor's real service life on the line.
• An IP67-rated housing protects the sensor's interior against dust and water jets, which matters when cleaning a welding station.
• The sensor is resistant to electromagnetic interference, keeping its output signal stable near operating resistance welding machines.
• 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.

When to choose this model

• When you need a sensor for a robotic welding process where reliable part detection is essential.
• If part detection is needed in a location with a strong electromagnetic field.
• When stable sensor operation matters despite the interference present in welding processes.
• When you need a sensor for welding automation that monitors the presence or position of a metal part.
