Safety and Operational Reliability
This module uses Unicode evaluation, providing the highest level of coding protection against tampering. The integrated Emergency Stop (ISO 13850) is illuminated, providing clear status feedback even in dark industrial settings. Because it utilizes the Push-Pull connection system, it is highly resistant to dirt and vibration, making it a standard choice for heavy machinery, metalworking, and automated robotic cells.
