Inductive sensor M12 for welding process 50 mm cable 2m PNP NC Sn = 4 mm

The NWI12014 inductive sensor for welding applications provides resistance to electromagnetic fields, metal spatter, oils, coolants, and other factors present in the production environment.

The M12 sensor works well as a universal solution for most welding and resistance-welding stations, 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: 4 mm, stable metal-detection characteristics even close to a resistance-welding machine's electromagnetic field
• Housing: Threaded, a threaded housing allows precise adjustment of the sensor's position relative to the weld point
• 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 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 2 m cable, a cable of suitable length makes it easy to route the wiring away from the hottest zone of the weld
• 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: W1CN-M1204P-C3U2
