1127781

Overview

The SICK model 1127781 is a safety light curtain from the M4000 series, designed for personnel protection in industrial automation. It features a resolution of 30 mm and a vertical measuring range of 600 mm. The device operates with a beam spacing of 30 mm and includes 21 light axes. It supports protective functions such as guarding and external device monitoring (EDM). The unit utilizes an M12 connector interface for power and data transmission, ensuring reliable integration into safety circuits.

Feature Summary

• Provides personnel protection through high-resolution light field detection
• Supports external device monitoring for enhanced system safety integrity
• Features coded beams to prevent interference from adjacent safety devices

Applications

• Machine guarding for press brakes and stamping machines
• Protection zones around robotic work cells
• Safety barriers for automated guided vehicle pathways

Procurement Notes

Verify the specific version suffix and connector type against the current SICK product catalog to ensure compatibility with existing control systems. Confirm that the resolution and height meet the required safety distance calculations per ISO 13855. Check for updated firmware requirements if integrating with newer PLC modules.

Selection Notes

Select this model based on the required resolution of 30 mm for personnel protection. Ensure the 600 mm height covers the necessary hazard zone. Verify that the M12 interface matches the available cabling infrastructure. Consider environmental factors such as ambient light and potential optical interference when deploying multiple units.

Part Context

This component belongs to the SICK M4000 series of safety light curtains, which are engineered for robust performance in harsh industrial environments. The series offers various resolutions and heights to suit different safety applications. The M4000 line emphasizes ease of installation and diagnostic capabilities to minimize downtime.

Replacement Considerations
