For applications requiring modern automation integration, the EVK2.11.2 features CANopen fieldbus interface for seamless communication with control systems. With measuring accuracy better than 1.0mm and support for distances up to 4 meters between sensor and light source, the EVK2.11.2 delivers precise and reliable performance. The system consumes less than 50 VA per drive unit and operates on 24V DC supply with 0.5A continuous current, making it efficient for continuous industrial operation.

The EVK2.11.2 is designed for easy installation in minimal space, reducing commissioning time significantly. With IP54 protection rating and operating temperature range of 0 to +50°C, the EVK2.11.2 solves the pain point of inaccurate strip edge detection in demanding steel processing environments. This sensor positioning device ensures precise, repeatable measurements insensitive to strip height variations and ambient light interference, maintaining product quality and process efficiency in metal processing applications worldwide.

The EVK2.11.2 ​EMG Board Device may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
