Inductive sensor M8 for welding process 60 mm connector M8 NPN NO Sn = 2 mm

The NWI08111 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 compact M8 size allows the sensor to be mounted directly on the arm of a welding robot without limiting its range of motion, Ø8 x 60 mm are dimensions that allow quick sensor replacement without dismantling the entire welding setup.

Technical specification:

• Diameter: M8, a convenient size for stations with limited mounting space
• Length: 60 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 2 mm, repeatable detection of metal parts regardless of the interference generated during 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, a PTFE layer on the brass housing reduces weld spatter sticking to the sensor's surface
• Sensor face material: PTFE, the PTFE coating on the sensing face makes cleaning the station easier without risking damage to the sensor
• 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), the NO function simplifies integration with most existing resistance-welding machine control systems
• Output type: NPN, the NPN output type works well with the typical PLC controller inputs on resistance-welding lines
• Connection: with a M8 plug connector, a plug connector allows quick sensor replacement without dismantling the entire welding installation
• 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: W1CN-M0802N-OPU3

Applications

• It performs well in robotic welding systems and robotic welding lines, where robots operate without constant operator supervision.
• 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.

Benefits/Features

• Thanks to its high resistance, it performs well in environments with high levels of electromagnetic interference, such as those generated by welding machines.
• 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.

When to choose this model

• When the sensor will be used on an automated welding line and must provide stable detection of metal parts.
• If reliable part detection is required in a resistance-welding machine.
• When the sensor must work together with a welding station's automation system.
• When you need an inductive sensor for a welding robot operating in a demanding environment.

Connection

The sensor has an NPN output, so connect it with an M8 3-pin connection cable without LEDs. Cables with LEDs (NXOC08261…, NXOC08121…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
