The IER203 operates using an inductive sensing principle to detect metallic objects without direct physical contact.
When a suitable metallic target enters the sensing zone, the sensor switches its PNP/NPN normally-open output. The resulting switching signal can be used by compatible PLCs, controllers and automation systems for position detection, machine sequencing, object detection and process control.
Its full-metal construction provides additional mechanical robustness, while the anti-spatter surface is designed to support operation in welding-related applications.
The IER203 provides a 2 mm sensing range with an increased sensing range.
The documented operating distance is 0–1.6 mm. The correction factor depends on the metallic target material and should be considered when designing the sensing application.
