Inductive sensor M18 for welding process 55 mm cable 2m NPN NO Sn = 8 mm

The NWI18011 inductive sensor, resistant to welding conditions, guarantees stable operation in automation systems, position control, and production processes that involve welding.

The M18 size enables detection of parts from a greater distance, which matters with large welded components, Ø18 x 55 mm is a compact format that does not restrict the freedom of movement of a welding robot.

Technical specification:

• Diameter: M18, a robust size that performs well in heavier resistance-welding applications
• Length: 55 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• 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, a PTFE layer on the brass housing reduces weld spatter sticking to the sensor's surface
• Sensor face material: PTFE, the PTFE material keeps detection parameters stable even after repeated contact with spatter
• Mounting: Non-flush mounting, the non-flush version makes use of the full detection range, useful with larger welded parts
• Switching function: normally open (NO), standard normally-open logic, compatible with the typical PLC controllers used on welding lines
• Output type: NPN, the NPN output type works well with the typical PLC controller inputs on resistance-welding lines
• 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-M1808N-O3U2

Applications

• It supports the operation of smart welding lines and smart welding stations integrated with higher-level control systems.
• 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.

Benefits/Features

• It can be used as a welding machine sensor resistant to interference and a resistance welding machine sensor resistant to electromagnetic interference.
• 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.

When to choose this model

• If you need a sensor for spot welding, where correct part positioning matters.
• If part detection is needed in a location with a strong electromagnetic field.
• If the application requires checking that a part is correctly positioned before resistance welding.
• When the model is to support resistance-welding process automation through part-position monitoring.
