Inductive sensor M18 for welding process 55 mm cable 2m NPN NC Sn = 5 mm

The NWI18002 inductive sensor for welding was developed for applications requiring resistance to abrasion, impact, and contamination, along with continuous operation in a harsh industrial environment.

The M18 size enables detection of parts from a greater distance, which matters with large welded components, 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: 5 mm, a proven detection range under conditions typical of robotic welding
• Housing: Threaded, a threaded housing allows precise adjustment of the sensor's position relative to the weld point
• 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: Flush mounting, the flush version allows the sensor to be recessed into the metal fixtures of the welding station
• 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, the NPN output type works well with the typical PLC controller inputs on resistance-welding lines
• 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, EMC resistance allows mounting close to a resistance-welding machine's coils and current-carrying cables without signal loss
• Catalog number: W1CF-M1805N-C3U2

Applications

• 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.
• It is used in welding machines and as an inductive sensor for welding machines, monitoring the position and presence of parts.

Benefits/Features

• 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.
• As an inductive sensor for harsh industrial conditions, it maintains repeatable detection even under intensive use.

When to choose this model

• When part-position monitoring is required during automated welding.
• When the sensor must monitor the presence and position of a part during resistance welding.
• If the model is to support the robotization of a welding station.
• If reliable detection is required at an automated welding or resistance-welding station.
