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

The modern NWI18001 Heavy Duty inductive sensor for welding guarantees long service life and reliable performance in applications exposed to intensive loads and harsh environmental conditions.

The M18 size enables detection of parts from a greater distance, which matters with large welded components, Ø18 x 55 mm is a format that provides secure mechanical mounting throughout the continuous-duty cycle of a resistance-welding line.

Technical specification:

• Diameter: M18, a format that provides a greater detection distance than the smaller diameters in this line
• Length: 55 mm, an extended housing that provides extra mounting rigidity under harsh welding conditions
• 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 material keeps detection parameters stable even after repeated contact with spatter
• 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: NPN, the NPN output type works well with the typical PLC controller inputs on resistance-welding lines
• 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 standard voltage range compatible with the power supply of most welding-line control cabinets
• Electromagnetic interference (EMC) resistance: yes, a stable output signal even in the immediate vicinity of the strong electromagnetic fields present during welding
• Catalog number: W1CF-M1805N-O3U2

Applications

• 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.
