Inductive sensor M18 for welding process 79 mm connector M12 PNP NC Sn = 8 mm

The reinforced NWI18114 inductive sensor for welders and industrial robots performs well in areas exposed to sparks, metal spatter, high temperatures, and interference generated during the welding process.

The M18 size enables detection of parts from a greater distance, which matters with large welded components, Ø18 x 79 mm is a format that provides secure mechanical mounting throughout the continuous-duty cycle of a resistance-welding line.

Technical specification:

• Diameter: M18, a robust size that performs well in heavier resistance-welding applications
• Length: 79 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 8 mm, a proven detection range under conditions typical of robotic welding
• Housing: Threaded, the housing thread allows fine adjustment of the detection distance during installation on the line
• 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, a PTFE sensing face prevents metal spatter from welding and resistance welding from sticking
• Mounting: Non-flush mounting, the non-flush version makes use of the full detection range, useful with larger welded parts
• Switching function: normally closed (NC), a normally-closed function useful in the safety circuits of welding stations
• Output type: PNP, the PNP output type simplifies integration with the safety modules of resistance-welding robots
• Connection: with a M12 plug connector, the plug connector simplifies servicing on the production line, reducing downtime at the resistance-welding station
• Supply voltage: DC 10-30V, a typical industrial automation supply voltage, with no need for additional converters
• Electromagnetic interference (EMC) resistance: yes, proven resistance to the electromagnetic interference generated by resistance-welding machines and welding robots
• Catalog number: W1CN-M1808P-CEU4

Applications

• It is used within the Industry 4.0 concept in welding and resistance welding, where sensor data feeds into production monitoring systems.
• It supports the robotization of welding processes and the robotization of resistance-welding processes, increasing line repeatability and throughput.
• It is used in production automation and production robotization at plants where welding and resistance welding are a key process step.
• The sensor is a common choice among industrial welding sensors and inductive sensors for welding, mounted directly at the workstation.
• It works well as a welding application sensor and sensor for welding applications, where stable detection of metal parts is essential.

Benefits/Features

• It maintains signal stability as a welding sensor resistant to electromagnetic interference, reducing the number of false detections.
• Stable operation of the inductive sensor in the welding environment and resistance to electromagnetic interference during welding are key features of this model.
• A robust, fully enclosed construction and high-quality housing materials ensure a long service life under continuous-duty cycles.
• The construction's resistance to weld spatter keeps the sensor working reliably even in direct contact with hot metal particles.
• The sensor is spatter-resistant against particles generated during welding and resistance welding, reducing the risk of damage to the sensing face.

When to choose this model

• When the welding process generates spatter that could contaminate the sensor's surface.
• When a standard sensor might be exposed to the electromagnetic interference generated during welding.
• When the application requires reliable detection without direct contact with the metal part.
• If reliable detection is required at an automated welding or resistance-welding station.
