2044663

Overview

The SICK model 2044663 is a component within the M2000 series, specifically identified as the M20Z-02550A220 variant. This device functions as a safety-related photoelectric sensor designed to protect personnel from hazardous machine areas. It complies with Type 2 (IEC 61496-1) and Category 2 (EN ISO 13849) standards. Key technical parameters include a Safety Integrity Level (SIL) of 1 (IEC 61508), a Performance Level (PL) of C, and a mean probability of dangerous failure per hour (PFHd) of 6.6x10^-9. The internal test rate is 13/s, with a mission time of 20 years. The unit weighs 1.356 kilograms and originates from Germany.

Feature Summary

• Provides safety protection by detecting interruptions in the light field to stop hazardous machine movements.
• Ensures safe state operation by maintaining at least one OSSD in the off state during faults.
• Supports application-specific configuration and fine adjustment for optimized system availability.

Applications

• Protection of hazardous zones around industrial machinery and equipment.
• Integration into complete safety control systems with controllers such as LE20.
• Installation at entry points to danger areas to prevent personnel access.

Procurement Notes

Verify the specific part number 1026511 against the required safety category and performance level for your application. Confirm compatibility with existing safety controllers like the LE20 if used in a monitored system. Ensure installation is performed by qualified technicians to maintain certification validity and ensure proper wiring and configuration according to official documentation.

Selection Notes

Select this variant based on its Type 2 classification and PL C rating, which suit applications requiring Category 2 compliance under EN ISO 13849. Consider the 20-year mission time and low PFHd value for long-term reliability requirements. Verify that the internal test rate of 13/s meets the operational demands without exceeding external test limitations defined in the standard.
