Inductive sensor M18 for welding process 55 mm cable 2m NPN NC Sn = 8 mm

The NWI18012 industrial inductive sensor for welding features high resistance to electromagnetic interference, weld spatter, and intensive use in a production environment.

The M18 sensor performs well at resistance-welding stations where a longer metal-detection range is required, Ø18 x 55 mm is a format that provides secure mechanical mounting throughout the continuous-duty cycle of a resistance-welding line.

Technical specification:

• Diameter: M18, a longer detection range while keeping a compact build, for welding robots
• Length: 55 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• Detection range: 8 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, 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 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-M1808N-C3U2

Applications

• 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.
• It belongs to the class of welding cell sensors and inductive sensors for welding cells, used in the enclosed working zones of robots.
• It is an excellent fit for welding stations and automated welding stations, where repeatable, downtime-free operation is required.

Benefits/Features

• 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.
• Designed to operate in a welding environment, it maintains stable parameters despite harsh ambient conditions.
• It performs well in harsh welding conditions, including elevated temperatures and heavy dust in the work zone.

When to choose this model

• When part-position monitoring is required during automated welding.
• When the sensor will operate under the harsh conditions of a welding process.
• When the sensor must work together with a welding station's automation system.
• If reliable detection is required at an automated welding or resistance-welding station.
