1131873

Overview

The SICK part number 1131873 corresponds to the M20S-04130A122 safety light curtain. This device provides protective operation with beam encoding and external device monitoring (EDM). It features a resolution of 25 mm and a scanning range of 300 mm. The unit utilizes an M12, 8-pin male connector for connectivity.

Feature Summary

• Provides protective operation with integrated beam encoding
• Supports external device monitoring (EDM) for enhanced safety verification
• Features a compact design suitable for space-constrained machinery guarding

Applications

• Machine guarding for industrial automation equipment
• Protection zones around press machines and stamping units
• Safety barriers for automated assembly lines

Procurement Notes

Verify the specific suffix codes on the product label against the ordering data to ensure correct connector type and feature set. Confirm that the required resolution and scanning range match the machine safety requirements before procurement. Ensure compatibility with the existing safety controller interface.

Selection Notes

Select this model when a 25 mm resolution is required for personnel protection. The 300 mm scanning range defines the vertical detection height. Choose based on the need for EDM functionality and the availability of M12 connectors in the system architecture.

Part Context

This component belongs to the SICK M2000 Standard series of safety light curtains. The series offers various configurations differing in beam count, resolution, and connection types to suit diverse industrial safety applications.

Replacement Considerations

Direct replacements include the M20E-04130A122 variant, which shares identical technical specifications but may differ in housing material or environmental rating. Verify mounting dimensions and electrical interfaces before substitution.
