Inductive sensor M18 for welding process 79 mm connector M12 NPN NO Sn = 5 mm

The rugged NWI18101 welding inductive sensor is a reliable solution for welding robots, resistance-welding stations, and automated production lines that require precise detection.

The M18 size enables detection of parts from a greater distance, which matters with large welded components, Ø18 x 79 mm are proportions that ensure stable detection even under the vibration generated by a resistance-welding machine.

Technical specification:

• Diameter: M18, a longer detection range while keeping a compact build, for welding robots
• Length: 79 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• Detection range: 5 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 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 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 M12 plug connector, the plug connector simplifies servicing on the production line, reducing downtime at the resistance-welding station
• Supply voltage: DC 10-30V, a typical industrial automation supply voltage, with no need for additional converters
• Electromagnetic interference (EMC) resistance: yes, proven resistance to the electromagnetic interference generated by resistance-welding machines and welding robots
• Catalog number: W1CF-M1805N-OEU4

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 the welding process requires non-contact detection of part presence.
• If you need a sensor for operation in a demanding resistance-welding environment.
• If the model is to support the robotization of a welding station.
• If the sensor is to be used in a robotic welding cell exposed to spatter.

Connection

The sensor has an NPN output, so connect it with an M12 4-pin connection cable without LEDs. Cables with LEDs (NXOC12281…, NXOC12401…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
