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

The NWI08113 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 small M8 dimensions make it easy to integrate with spot-welding gun holders, where every millimeter of space counts, Ø8 x 60 mm is a format that provides good mounting accessibility while maintaining a rugged construction resistant to welding conditions.

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: 2 mm, a proven detection range under conditions typical of robotic welding
• Housing: Threaded, the housing thread allows fine adjustment of the detection distance during installation on the line
• 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 coating on the sensing face makes cleaning the station easier without risking damage to the sensor
• Mounting: Non-flush mounting, non-flush mounting provides a longer detection range when adequate mounting space is available
• Switching function: normally open (NO), the NO function simplifies integration with most existing resistance-welding machine control systems
• Output type: PNP, a PNP output that is standard for most new welding automation installations
• Connection: with a M8 plug connector, the plug connector simplifies servicing on the production line, reducing downtime at the resistance-welding station
• 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, a stable output signal even in the immediate vicinity of the strong electromagnetic fields present during welding
• Catalog number: W1CN-M0802P-OPU3

Applications

• 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.
• It is a component of welding process control systems and resistance welding process control systems, confirming the presence and position of parts.

Benefits/Features

• 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.
• It is suited to operation in a strong electromagnetic field, typical of resistance welding and arc welding.

When to choose this model

• When the sensor must operate in an industrial resistance-welding machine exposed to harsh operating conditions.
• When the sensor must monitor the presence and position of a part during resistance welding.
• When the sensor must confirm part presence before a welding operation is performed.
• When part-position monitoring is needed in an automated welding process.
