NWI18014

The reinforced NWI18014 inductive sensor for welders and industrial robots performs well in areas exposed to sparks, metal spatter, high temperatures, and interference generated during the welding process.

The M18 format provides extra mechanical resistance when operating under the harsh conditions of a welding line, Ø18 x 55 mm is a compact format that does not restrict the freedom of movement of a welding robot.

Technical specification:

• Diameter: M18, a longer detection range while keeping a compact build, for welding robots
• Length: 55 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• Detection range: 8 mm, repeatable detection of metal parts regardless of the interference generated during welding
• 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, 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 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-M1808P-C3U2

Applications

• It supports position control in resistance welding, signaling the machine controller that a part is present in the work zone.
• It is used in welding automation systems and resistance welding automation systems as a feedback element for the PLC controller.
• 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.
• It performs well in robotic welding systems and robotic welding lines, where robots operate without constant operator supervision.

Benefits/Features

• As an inductive sensor resistant to electromagnetic interference, it does not generate false triggers during the welding cycle.
• Proven to be resistant to electromagnetic fields, it operates reliably even in the immediate vicinity of the coils and current-carrying cables of a welding machine.
• 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.

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 stable sensor operation matters despite the interference present in welding processes.
• When you need a sensor for welding automation that monitors the presence or position of a metal part.
