The IFM IGR202 is a high-performance inductive proximity sensor specifically designed for welding applications and other harsh industrial environments. Combining rugged full-metal construction, increased sensing range, and immunity to magnetic fields, it delivers dependable detection in situations where standard sensors would fail.

One of the defining features of the IGR202 is its magnetic-field immune design. Welding environments often generate strong electromagnetic fields that can disrupt conventional sensors, leading to false triggers or missed detections. The IGR202 eliminates this risk, ensuring accurate and stable performance even when installed close to welding equipment, transformers, or other sources of magnetic interference.

The sensor features a 6 mm sensing range, which provides increased flexibility for installation. With IFM’s increased sensing range technology, the IGR202 can be positioned further from the target surface while still delivering precise detection. This reduces wear from spatter, vibration, or mechanical impact, extending the sensor’s operational life in challenging conditions.

Housed in a robust full-metal body (M18 x 1, 70 mm length), the IGR202 is built to withstand the extreme demands of welding environments. The all-metal construction provides excellent resistance to mechanical stress, sparks, and weld spatter, making it suitable for use directly in production lines and robotic welding cells. Its threaded housing ensures easy and secure installation into standard fittings, while offering long-term reliability.

Electrical design is equally robust. The IGR202 employs an NPN output configuration with a normally open (NO) switching function, providing straightforward integration into existing control systems. The inclusion of gold-plated contacts enhances conductivity and ensures corrosion resistance, protecting the sensor from performance degradation over time. This guarantees consistent switching behaviour, even in environments exposed to oils, moisture, or contaminants.

Engineered for industrial welding applications, the IGR202 is an essential tool in industries such as automotive manufacturing, heavy equipment production, and metal fabrication. Its ability to withstand weld spatter, heat, and magnetic interference makes it a reliable choice for monitoring positions, detecting workpieces, or safeguarding automated welding systems.

By delivering accurate non-contact detection under extreme conditions, the IGR202 helps operators maintain system uptime, prevent false signals, and reduce maintenance requirements. This results in greater productivity, improved safety, and lower long-term operating costs.

In summary, the IFM IGR202 is a rugged inductive proximity sensor that combines a magnetic-field immune design, full-metal housing, extended sensing range, and gold-plated contacts to deliver unmatched reliability in welding applications. Built for durability and precision, it ensures dependable performance in environments where conventional sensors are not sufficient, making it a trusted solution for modern automated welding and heavy-duty industrial processes.
