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

The NWI18013 inductive sensor for welding applications provides resistance to electromagnetic fields, metal spatter, oils, coolants, and other factors present in the 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 well matched to the typical mounting brackets used at welding stations.

Technical specification:

• Diameter: M18, a longer detection range while keeping a compact build, for welding robots
• Length: 55 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 8 mm, repeatable detection of metal parts regardless of the interference generated during 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, a PTFE sensing face prevents metal spatter from welding and resistance welding from sticking
• Mounting: Non-flush mounting, non-flush mounting provides a longer detection range when adequate mounting space is available
• Switching function: normally open (NO), standard normally-open logic, compatible with the typical PLC controllers used on welding lines
• Output type: PNP, the PNP output type simplifies integration with the safety modules of resistance-welding robots
• 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 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-M1808P-O3U2

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

• If the sensor needs to operate in a welding cell exposed to electromagnetic interference.
• If reliable part detection is required in a resistance-welding machine.
• When the sensor must confirm part presence before a welding operation is performed.
• When the model is to support resistance-welding process automation through part-position monitoring.
