The NWI12112 Heavy Duty industrial inductive sensor delivers reliable operation near welding stations, where high temperatures, strong electromagnetic fields, and weld spatter are present.
The M12 format provides solid mechanical mounting while keeping the housing dimensions compact, Ø12 x 68 mm are dimensions that allow quick sensor replacement without dismantling the entire welding setup.
Technical specification:
- Diameter: M12, a good compromise between size and detection range in welding applications
- Length: 68 mm, a longer sensor body that allows mounting further away from the hottest zone of the weld
- Detection range: 4 mm, stable metal-detection characteristics even close to a resistance-welding machine's electromagnetic field
- 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: Non-flush mounting, the non-flush version makes use of the full detection range, useful with larger welded parts
- Switching function: normally closed (NC), NC logic detects a missing part as an active signal, which makes it easier to control the resistance-welding process
- 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, the plug connector simplifies servicing on the production line, reducing downtime at the resistance-welding station
- 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: W1CN-M1204N-CEU4
Applications
- 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.
- It supports the operation of smart welding lines and smart welding stations integrated with higher-level control systems.
- It is used within the Industry 4.0 concept in welding and resistance welding, where sensor data feeds into production monitoring systems.
Benefits/Features
- 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.
- It can be used as a welding machine sensor resistant to interference and a resistance welding machine sensor resistant to electromagnetic interference.
- It maintains signal stability as a welding sensor resistant to electromagnetic interference, reducing the number of false detections.
When to choose this model
- When you need an inductive sensor for a welding cell where weld spatter is present.
- When the sensor will operate under the harsh conditions of a welding process.
- If the application requires checking that a part is correctly positioned before resistance welding.
- When you need a sensor for welding automation that monitors the presence or position of a metal part.
Connection
The sensor has an NPN output, so connect it with an M12 4-pin connection cable without LEDs. Cables with LEDs (NXOC12281…, NXOC12401…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
The diameter of an inductive sensor is a dimension that defines the width of the sensor element measured in millimeters. This is an important technical parameter as it affects the mounting method and the space required for installation.
Rated detection range is a key parameter of an inductive sensor.Indicates the distance at which the sensor changes its output state when a metal object approaches its front end axially.This is the sensor's most important functional feature—it determines how close the object being detected must be in order to be registered.
