Inductive sensor M12 for welding process 50 mm cable 2m PNP NO Sn = 2 mm

The NWI12003 industrial welding inductive sensor combines a compact design with high mechanical and environmental resistance, ensuring dependable operation in demanding applications.

The M12 format provides solid mechanical mounting while keeping the housing dimensions compact, Ø12 x 50 mm is a format well matched to the typical mounting brackets used at welding stations.

Technical specification:

• Diameter: M12, a good compromise between size and detection range in welding applications
• Length: 50 mm, a short length that makes mounting easier in densely packed welding stations
• 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, a PTFE sensing face prevents metal spatter from welding and resistance welding from sticking
• 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: 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-M1202P-O3U2

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 the sensor will be used on an automated welding line and must provide stable detection of metal parts.
• When the model is to be used in a robotic resistance-welding process.
• When component detection is needed on an automated welding or resistance-welding line.
• If the sensor is to be used in a robotic welding cell exposed to spatter.
