NWI12102

The NWI12102 Heavy Duty industrial inductive sensor delivers reliable operation near welding stations, where high temperatures, strong electromagnetic fields, and weld spatter are present.

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: 2 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 coating on the sensing face makes cleaning the station easier without risking damage to the sensor
• Mounting: Flush mounting, the flush version allows the sensor to be recessed into the metal fixtures of the welding station
• 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 standard voltage range compatible with the power supply of most welding-line control cabinets
• Electromagnetic interference (EMC) resistance: yes, proven resistance to the electromagnetic interference generated by resistance-welding machines and welding robots
• Catalog number: W1CF-M1202N-CEU4

Applications

• Used on resistance-welding lines and automated resistance welding lines, where cycle repeatability matters most.
• It functions as a position sensor for resistance welding machines and a part-presence sensor for resistance welding, confirming correct part placement before the cycle.
• 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.

Benefits/Features

• An IP67-rated housing protects the sensor's interior against dust and water jets, which matters when cleaning a welding station.
• The sensor is resistant to electromagnetic interference, keeping its output signal stable near operating resistance welding machines.
• 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.

When to choose this model

• When you need a sensor for a robotic welding process where reliable part detection is essential.
• When the sensor will operate under the harsh conditions of a welding process.
• When component detection is needed on an automated welding or resistance-welding line.
• When you need an inductive sensor for a welding robot operating in a demanding environment.
