Inductive sensor M8 for welding process 45 mm cable 2m PNP NC Sn = 1 mm

The NWI08004 inductive sensor for welding robots is a robust component of modern automation systems, delivering stable performance in Heavy Duty applications.

Thanks to its small M8 diameter, the sensor can be mounted in hard-to-reach locations around the welding station, Ø8 x 45 mm is a format optimized for mounting in the confined spaces of welding robots.

Technical specification:

• Diameter: M8, the smallest size in this line, good for tight spaces in spot welding
• Length: 45 mm, a compact housing, convenient where mounting space around the resistance-welding machine is limited
• Detection range: 1 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, a PTFE sensing face prevents metal spatter from welding and resistance welding from sticking
• Mounting: Flush mounting, flush mounting protects the sensor from side impacts and spatter
• 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: PNP, a PNP output that is standard for most new welding automation installations
• Connection: with a 2 m cable, a cable resistant to the vibration and frequent movement typical of welding robots
• 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-M0801P-C3U2

Applications

• 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.
• It supports position control in resistance welding, signaling the machine controller that a part is present in the work zone.
• It is used in welding automation systems and resistance welding automation systems as a feedback element for the PLC controller.

Benefits/Features

• 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.
• As an inductive sensor resistant to electromagnetic interference, it does not generate false triggers during the welding cycle.
• Proven to be resistant to electromagnetic fields, it operates reliably even in the immediate vicinity of the coils and current-carrying cables of a welding machine.

When to choose this model

• When the application involves resistance welding and requires part-presence monitoring.
• When the resistance-welding process requires non-contact detection of metal parts.
• When the production process combines a high degree of automation with demanding welding conditions.
• When you need an inductive sensor for a welding robot operating in a demanding environment.
