Overview

The SICK M20S-081A2A122 is a safety light curtain featuring 81 vertical beams with a 25 mm resolution and a maximum scanning range of 16 meters. It supports protective operation, beam coding, and external device monitoring (EDM). The unit utilizes an M12, 8-pin male connector for connectivity. This model is designed to detect personnel intrusion into hazardous zones, providing reliable safeguarding for industrial machinery by generating a light field that triggers machine stop upon interruption.

Feature Summary

• Beam coding technology ensures reliable detection and prevents interference from adjacent safety devices.
• Supports External Device Monitoring (EDM) for comprehensive safety circuit verification.
• Compact design with high beam density suitable for precise hazard zone protection.

Applications

• Protective guarding for press brakes and stamping machines
• Hazard zone monitoring around automated assembly robots
• Safety barriers for packaging and material handling equipment

Procurement Notes

Verify the specific suffix codes on the product label against the official SICK ordering catalog to confirm the exact configuration, including connector type and functional scope. Ensure compatibility with the intended safety controller's input requirements and voltage specifications before procurement.

Selection Notes

Select this model based on the required protection height and object detection resolution. Confirm that the 25 mm beam spacing meets the safety distance calculations for the specific application risk assessment. Verify that the M12 connector interface aligns with the existing cabling infrastructure.
