1142956

Overview

The SICK model 1142956 is a safety light curtain belonging to the M2000 Standard series, designed for personnel protection in industrial environments. It features an optical axis separation of 25 mm and a scanning range of 116 mm. The device incorporates beam coding and external device monitoring (EDM) functions to ensure operational reliability. It utilizes an M12, 8-pin male connector for connection. The unit supports protective operation modes and is engineered for robust industrial use with high resistance to environmental interference.

Feature Summary

• Integrates beam coding technology to prevent false triggering from ambient light or cross-talk
• Supports external device monitoring (EDM) for comprehensive safety circuit verification
• Features a compact housing design suitable for installation in tight spaces
• Provides reliable personnel protection through precise optical axis separation

Applications

• Personnel protection at press brakes and stamping machines
• Safety guarding for injection molding machines
• Protection zones around automated assembly stations
• Perimeter safety monitoring in logistics automation systems

Procurement Notes

Verify that the ordering number 1142956 corresponds to the specific M2000 Standard variant with 25 mm resolution and 116 mm scan range. Confirm compatibility with existing safety controllers regarding the M12 8-pin interface and EDM requirements. Ensure the selected accessory cables match the connector type and length specifications required for the installation layout. Cross-reference the technical data sheet for ambient light resistance ratings relevant to the specific factory lighting conditions.

Selection Notes

Select this model when a 25 mm resolution is sufficient for personnel protection rather than finger detection. The 116 mm scanning range indicates a short vertical dimension, suitable for lower guard openings or specific machine footprints. The inclusion of EDM and beam coding makes it appropriate for complex safety circuits requiring high availability and interference immunity. Compare against other M2000 variants if different resolutions or longer scan ranges are needed for larger machinery guards.

Part Context

This component is part of the SICK M2000 Standard safety light curtain family, which offers modular solutions for machine safety. The M2000 series is known for its uniform housing and mounting systems, simplifying integration across various equipment types. Model 1142956 specifically represents a configuration optimized for applications requiring moderate resolution and short detection fields, leveraging the series' robust industrial design and standardized connectivity options.

Replacement Considerations

Direct replacement requires matching the 25 mm resolution, 116 mm scan range, and M12 8-pin connector. Verify that the new unit supports the same beam coding and EDM functionalities. Check for any firmware or software compatibility issues if integrating with legacy safety PLCs. Ensure the mechanical mounting dimensions are identical to avoid structural modifications.
