NWI30112

The NWI30112 inductive sensor for welding applications is designed for reliable operation in demanding industrial conditions, ensuring stable detection of metal parts even close to welding processes.

The M30 format allows mounting in the heavy-duty holders of resistance-welding machines without any loss of mechanical stability, Ø30 x 79 mm is a format optimized for mounting in the confined spaces of welding robots.

Technical specification:

• Diameter: M30, the largest size in the range, for applications requiring a long detection distance
• Length: 79 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 15 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: 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: NPN, the NPN output type works well with the typical PLC controller inputs on resistance-welding lines
• 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 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-M3015N-CEU4

Applications

• It is an excellent fit for welding stations and automated welding stations, where repeatable, downtime-free operation is required.
• It is used in welding machines and as an inductive sensor for welding machines, monitoring the position and presence of parts.
• It is used in welding robots as an inductive sensor for welding robots, ensuring reliable detection throughout the work cycle.
• It performs well in robotic welding stations and automated welding lines, where every stoppage carries a real cost.
• Deployed on welding lines, it supports welding automation and the robotization of welding in series production.

Benefits/Features

• It performs well in harsh welding conditions, including elevated temperatures and heavy dust in the work zone.
• As an inductive sensor for harsh industrial conditions, it maintains repeatable detection even under intensive use.
• Resistance to harsh operating conditions allows mounting close to the weld point without compromising reliability.
• A construction resistant to harsh industrial conditions ensures stable operation across continuous, multi-shift cycles.
• 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.

When to choose this model

• If part-presence monitoring is needed at an automated welding station.
• When the model is to be used in a robotic resistance-welding process.
• When automatic part-position monitoring is required before welding begins.
• When you need a sensor for welding automation that monitors the presence or position of a metal part.
