Inductive sensor M30 for welding process 79 mm connector M12 PNP NC Sn = 15 mm

The versatile NWI30114 welding inductive sensor combines high resistance to industrial conditions, reliable metal detection, and long service life in demanding production processes.

The M30 size delivers the maximum detection range in this product line, useful for large resistance-welded structures, Ø30 x 79 mm is a format well matched to the typical mounting brackets used at welding stations.

Technical specification:

• Diameter: M30, a rugged construction built for the most demanding resistance-welding stations
• Length: 79 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 15 mm, repeatable detection of metal parts regardless of the interference generated during welding
• Housing: Threaded, the housing thread allows fine adjustment of the detection distance during installation on the line
• 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 material keeps detection parameters stable even after repeated contact with spatter
• Mounting: Non-flush mounting, the non-flush version makes use of the full detection range, useful with larger welded parts
• 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, the PNP output type simplifies integration with the safety modules of resistance-welding robots
• Connection: with a M12 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, a stable output signal even in the immediate vicinity of the strong electromagnetic fields present during welding
• Catalog number: W1CN-M3015P-CEU4

Applications

• It is a component of welding process control systems and resistance welding process control systems, confirming the presence and position of parts.
• It is used in automated welding systems and automated resistance welding systems operating continuously.

Benefits/Features

• It is suited to operation in a strong electromagnetic field, typical of resistance welding and arc welding.
• Its proven EMC resistance is valued by integrators building EMC-resistant industrial sensors for welding and resistance-welding applications.
• Thanks to its high resistance, it performs well in environments with high levels of electromagnetic interference, such as those generated by welding machines.
• It can be used as a welding machine sensor resistant to interference and a resistance welding machine sensor resistant to electromagnetic interference.
• It maintains signal stability as a welding sensor resistant to electromagnetic interference, reducing the number of false detections.

When to choose this model

• When a sensor is required for a welding machine that must withstand the influence of the process environment.
• When the sensor will operate under the harsh conditions of a welding process.
• If the sensor is to be used in a location exposed to both spatter and electromagnetic interference at the same time.
• When part-position monitoring is needed in an automated welding process.
