NWI30012

The NWI30012 Heavy Duty industrial inductive sensor delivers reliable operation near welding stations, where high temperatures, strong electromagnetic fields, and weld spatter are present.

The M30 size delivers the maximum detection range in this product line, useful for large resistance-welded structures, Ø30 x 55 mm are proportions that ensure stable detection even under the vibration generated by a resistance-welding machine.

Technical specification:

• Diameter: M30, a rugged construction built for the most demanding resistance-welding stations
• Length: 55 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 15 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, 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 closed (NC), NC logic detects a missing part as an active signal, which makes it easier to control the resistance-welding process
• Output type: NPN, an NPN output compatible with the controllers commonly used in welding automation
• Connection: with a 2 m cable, a cable resistant to the vibration and frequent movement typical of welding robots
• 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-M3015N-C3U2

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 the application involves welding robots operating in harsh industrial conditions.
• When you need a sensor for a resistance-welding machine subject to strong electromagnetic interference.
• When automatic part-position monitoring is required before welding begins.
• If reliable detection is required at an automated welding or resistance-welding station.
