Overview

The SICK M20S-081A2A122 is a safety light curtain designed for personnel protection in industrial environments. It features 81 beams with a resolution of 25 mm and a protective field height of 16 mm. The device supports protective operation, beam coding, and external device monitoring (EDM). It utilizes an M12, 8-pin male connector for connectivity. This model ensures reliable detection of intrusions into hazardous areas, complying with stringent safety standards for machinery guarding applications.

Feature Summary

• Provides personnel protection through high-resolution beam detection
• Integrates beam coding to prevent interference from adjacent units
• Supports external device monitoring for enhanced system reliability

Applications

• Guarding access points to hazardous machinery zones
• Protection around press brakes and stamping machines
• Safety monitoring at robotic cell entry points

Procurement Notes

Verify the specific suffix (e.g., A122 vs A120) matches your required connector type and feature set. Confirm that the ordering number 1018196 corresponds exactly to the M20S-081A2A122 variant with EDM support. Ensure compatibility with existing safety controllers regarding signal timing and wiring requirements before finalizing procurement.

Selection Notes

Select this model when a 25 mm resolution is required for personnel protection. Choose the M12 connector variant if using standard M12 cabling infrastructure. Consider the M26/Hirschmann version only if specific legacy connector compatibility is mandated. Verify that the 16 mm height meets the spatial constraints of the installation site while providing adequate coverage.

Part Context

This component belongs to the SICK M2000 Standard series of safety light curtains. The series offers various beam counts and resolutions tailored for different safety integrity levels. The M20S designation indicates the sender unit, which works in conjunction with a receiver unit to establish the protective field across hazardous areas.

Replacement Considerations

Direct replacement requires matching the 81-beam count, 25 mm resolution, and M12 connector interface. Verify that the new unit supports beam coding and EDM if these functions are active in the current safety circuit. Cross-reference ordering numbers to ensure identical electrical and mechanical specifications.
