Inductive sensor M12 for welding process 68 mm connector M12 PNP NC Sn = 4 mm

The NWI12114 inductive sensor for welding robots is a robust component of modern automation systems, delivering stable performance in Heavy Duty applications.

The M12 sensor works well as a universal solution for most welding and resistance-welding stations, Ø12 x 68 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: 68 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• 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, 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: Non-flush mounting, non-flush mounting provides a longer detection range when adequate mounting space is available
• Switching function: normally closed (NC), a normally-closed function useful in the safety circuits of welding stations
• Output type: PNP, the PNP output type simplifies integration with the safety modules of resistance-welding robots
• Connection: with a M12 plug connector, the plug connector simplifies servicing on the production line, reducing downtime at the resistance-welding station
• Supply voltage: DC 10-30V, a typical industrial automation supply voltage, with no need for additional converters
• Electromagnetic interference (EMC) resistance: yes, proven resistance to the electromagnetic interference generated by resistance-welding machines and welding robots
• Catalog number: W1CN-M1204P-CEU4

Applications
