7020669

Overview

The SICK part number 7020669 corresponds to the M20S-081A2A122 safety light curtain. This device features a beam count of 22 and an optical axis separation of 16 mm, providing a resolution of 25 mm for object detection. The effective scanning range extends up to 8 meters. It supports protective operation modes including beam coding and External Device Monitoring (EDM). The unit is equipped with an M12, 8-pin male connector for interface connectivity.

Feature Summary

• Supports protective operation with beam coding functionality
• Includes External Device Monitoring (EDM) capability
• Utilizes an M12, 8-pin male connector interface

Applications

• Machine guarding applications requiring personnel protection
• Safety zones around automated industrial equipment
• Access monitoring for hazardous machinery areas

Procurement Notes

Verify that the specific order code matches the required configuration, as variations exist within the M20 series regarding connector types and cable lengths. Confirm compatibility with the existing safety controller's input requirements. Ensure the selected model meets the necessary performance level and category standards for the intended application environment.

Selection Notes

Select this model when a 25 mm resolution is sufficient for the safety zone requirements. The 22-beam configuration offers a balance between coverage area and sensitivity. Consider the M12 connector type if it aligns with the facility's standard cabling infrastructure. Evaluate the maximum working distance of 8 meters against the physical layout of the protected area.

Part Context

This component belongs to the SICK M20 series of safety light curtains, designed for robust industrial environments. The series provides standardized solutions for machine safety, integrating easily into control systems. The M20S variant specifically denotes the sender or receiver unit configuration within the paired system setup.

Replacement Considerations

Publicly confirmed substitute part numbers include 1018196. Verify functional equivalence regarding beam count, resolution, and interface specifications before substitution.
