The IFM IEW200 is a specialised inductive proximity sensor engineered for welding applications, where standard sensors often struggle due to harsh conditions. With its 3 mm sensing range, magnetic-field immunity, and rugged construction, the IEW200 ensures reliable detection of metallic objects in environments affected by high heat, weld spatter, and electromagnetic interference.

Equipped with an increased sensing system, the IEW200 provides accurate detection of metallic targets at a 3 mm range. This short but precise sensing distance is ideal for part presence verification, fixture monitoring, and process control in welding lines where precision and consistency are critical to productivity and safety.

One of its most important advantages is its magnetic-field immunity. Welding operations often generate strong electromagnetic fields that can disrupt or cause false switching in conventional sensors. The IEW200 is specifically engineered to resist these disturbances, ensuring stable performance even in close proximity to welding robots, automated welding equipment, or high-current drives.

The sensor’s housing design combines compactness with durability. Measuring M8 x 1 with a 40 mm length, the threaded tubular body makes installation straightforward, even in tight machine spaces or robotic systems where space is limited. The rugged housing withstands vibration, shock, and the extreme conditions present in welding environments, including exposure to weld spatter and high thermal stress.

Electrically, the IEW200 operates on 10…30 V DC and features a PNP normally open (NO) output. The NO configuration ensures that the output switches only when a metallic target is detected, simplifying integration with programmable logic controllers (PLCs) and other control devices. This straightforward signal logic improves reliability in automated welding cells and complex production lines.

By utilising inductive technology, the IEW200 provides non-contact detection, eliminating mechanical wear and extending service life. Its maintenance-free operation is particularly valuable in welding environments, where downtime is costly and production continuity is essential.

The IEW200 is tailored for industries that rely heavily on welding, such as automotive manufacturing, heavy equipment fabrication, and robotic welding systems. In automotive assembly, it ensures accurate detection of components during welding stages. In robotic welding applications, its compact size and spatter-resistant design make it easy to integrate without compromising performance. In heavy manufacturing, it provides reliable monitoring of fixtures and welded parts under demanding conditions.

In summary, the IFM IEW200 is a rugged, precise, and welding-optimised inductive sensor. With its 3 mm sensing range, magnetic-field immunity, compact M8 x 1 housing, and resistance to welding spatter and heat, it provides a dependable, long-lasting solution for engineers seeking reliable object detection in welding-intensive industrial environments.
