2011432

Overview

The SICK model 2011432 is a safety light curtain system designed for personnel protection in industrial environments. It operates as a Type 2 safety device compliant with IEC 61496-1 standards, ensuring reliable detection of hazardous areas. The unit supports Safety Integrity Level SIL 1 according to IEC 61508 and meets Category 2 requirements under EN ISO 13849. Key performance metrics include an internal test rate of 13 per second and a maximum demand rate of 8 minutes inverse. The system achieves Performance Level PL C with a mean probability of dangerous failure per hour (PFD) of 6.6x10^-9. Designed for a mission time of 20 years, the device enters a safe state by turning off at least one OSSD upon fault detection.

Feature Summary

• Provides reliable personnel protection through certified safety light curtain technology
• Ensures immediate safe state response by deactivating output signals during fault conditions
• Supports high-frequency internal testing to maintain operational integrity within defined limits

Applications

• Personnel protection zones around automated machinery
• Hazardous area monitoring in manufacturing plants
• Safety interlocking for press and stamping operations
• Access protection for robotic work cells

Procurement Notes

Verify that the specific order number matches the required resolution and protective field height for your application. Confirm compatibility with existing safety controllers and wiring interfaces. Ensure all documentation references the correct revision level for compliance auditing. Cross-check technical drawings against site constraints before installation planning.

Selection Notes

Select this model based on the need for Type 2 safety architecture and PL C performance. Evaluate the 13 Hz internal test rate against your external test requirements to ensure compliance with the 100-test rule. Consider the 20-year mission time for long-term deployment scenarios. Assess the SIL 1 rating against your overall system safety design goals.

Part Context

This component belongs to the SICK safety sensor portfolio, focusing on light curtains for direct personnel protection. It integrates into broader safety systems managed by configuration tools like Safety Designer. The product line emphasizes standardized safety parameters and robust mechanical design for industrial durability.

Replacement Considerations

Consult official SICK substitution guides for compatible upgrades or legacy replacements. Verify that any substitute maintains identical Type 2 classification and PL C performance levels. Ensure interface compatibility with current control hardware before swapping units.

FAQ

What is the default safe state if a fault occurs?

At least one OSSD (Optically Switched Signal Device) turns off to halt the monitored process.

How does the internal test rate affect external testing?

The internal test rate is 13/s; if external tests are performed, they must not exceed this frequency limit.
