Inductive sensor M8 for welding process 60 mm connector M8 NPN NC Sn = 1 mm

The versatile NWI08102 welding inductive sensor combines high resistance to industrial conditions, reliable metal detection, and long service life in demanding production processes.

Because of its small M8 size, the sensor does not interfere with welding equipment mounted in its immediate vicinity, Ø8 x 60 mm is a format optimized for mounting in the confined spaces of welding robots.

Technical specification:

• Diameter: M8, a convenient size for stations with limited mounting space
• Length: 60 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• Detection range: 1 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, 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: 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, an NPN output compatible with the controllers commonly used in welding automation
• 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 typical industrial automation supply voltage, with no need for additional converters
• Electromagnetic interference (EMC) resistance: yes, a stable output signal even in the immediate vicinity of the strong electromagnetic fields present during welding
• Catalog number: W1CF-M0801N-CPU3

Applications

• 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.
• It is used in resistance-welding robots as an inductive sensor for resistance-welding robots, operating in the immediate vicinity of the weld point.
• Used on resistance-welding lines and automated resistance welding lines, where cycle repeatability matters most.
• It functions as a position sensor for resistance welding machines and a part-presence sensor for resistance welding, confirming correct part placement before the cycle.

Benefits/Features

• 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.
• A construction resistant to the welding environment and to spatter generated during welding extends the sensor's real service life on the line.
• An IP67-rated housing protects the sensor's interior against dust and water jets, which matters when cleaning a welding station.
• The sensor is resistant to electromagnetic interference, keeping its output signal stable near operating resistance welding machines.

When to choose this model

• When the welding process requires non-contact detection of part presence.
• When the application requires operation in a welding and resistance-welding environment exposed to spatter.
• When stable sensor operation matters despite the interference present in welding processes.
• 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.
