Inductive sensor M8 for welding process 60 mm connector M8 NPN NO Sn = 1 mm

The versatile NWI08101 welding inductive sensor combines high resistance to industrial conditions, reliable metal detection, and long service life in demanding production processes.

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 is a compact format that does not restrict the freedom of movement of a welding robot.

Technical specification:

• Diameter: M8, a compact diameter that makes mounting on a welding robot arm easier
• Length: 60 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• Detection range: 1 mm, stable metal-detection characteristics even close to a resistance-welding machine's electromagnetic field
• 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 open (NO), standard normally-open logic, compatible with the typical PLC controllers used on welding lines
• 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, proven resistance to the electromagnetic interference generated by resistance-welding machines and welding robots
• Catalog number: W1CF-M0801N-OPU3

Applications

• Deployed on welding lines, it supports welding automation and the robotization of welding in series production.
• It works well as a resistance welding sensor and resistance-welding equipment sensor, mounted directly on the arm or gun holder of the welding machine.
• It is an inductive sensor for resistance welding, used where the process generates a strong electromagnetic field and high temperatures.
• Used in resistance welding machines and resistance-welding equipment, it supports precise positioning of parts before welding.
• It works well as a spot welding sensor and supports resistance welding automation on production lines.

Benefits/Features

• The sensor is heat-resistant, withstanding the high temperatures generated during welding and resistance welding while maintaining its operating parameters across a -25°C to +70°C range.
• Being temperature-resistant, it can operate in the immediate vicinity of the heat-affected zone without risk of overheating its electronic components.
• A sensing face that is resistant to contamination and resistant to dust maintains stable detection sensitivity even in heavily dust-laden production halls.
• It performs well in heavy-duty operating conditions, typical of welding and resistance-welding shops, where sensors are exposed to vibration and contamination.
• As an industrial sensor for harsh conditions, it is a popular choice for demanding industrial applications and demanding welding applications.

When to choose this model

• When you need an inductive sensor for a welding cell where weld spatter is present.
• When the application requires operation in a welding and resistance-welding environment exposed to spatter.
• When the production process combines a high degree of automation with demanding welding conditions.
• When the application requires a sensor for a robotic resistance-welding line.

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.
