Inductive sensor M18 for welding process 55 mm cable 2m PNP NO Sn = 5 mm

The NWI18003 inductive sensor for welding was developed for applications requiring resistance to abrasion, impact, and contamination, along with continuous operation in a harsh industrial environment.

The M18 sensor performs well at resistance-welding stations where a longer metal-detection range is required, Ø18 x 55 mm are proportions that ensure stable detection even under the vibration generated by a resistance-welding machine.

Technical specification:

• Diameter: M18, a robust size that performs well in heavier resistance-welding applications
• Length: 55 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
• Detection range: 5 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 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 open (NO), the NO function simplifies integration with most existing resistance-welding machine control systems
• 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 standard voltage range compatible with the power supply of most welding-line control cabinets
• Electromagnetic interference (EMC) resistance: yes, EMC resistance allows mounting close to a resistance-welding machine's coils and current-carrying cables without signal loss
• Catalog number: W1CF-M1805P-O3U2

Applications

• 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.
• It is used in automated welding systems and automated resistance welding systems operating continuously.

Benefits/Features

• 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.
• Its proven EMC resistance is valued by integrators building EMC-resistant industrial sensors for welding and resistance-welding applications.

When to choose this model

• If the sensor needs to operate in a welding cell exposed to electromagnetic interference.
• When the resistance-welding process takes place on an automated production line.
• If the sensor is to be used in a location exposed to both spatter and electromagnetic interference at the same time.
• When you need an inductive sensor for a welding robot operating in a demanding environment.
