1053449

Overview

The SICK model 1053449 is a safety light curtain from the M2000 series, designed for personnel protection in industrial environments. It operates as a Type 2 safety device compliant with IEC 61496-1 and achieves Safety Integrity Level SIL 1 per IEC 61508. The unit functions within Category 2 according to EN ISO 13849, offering a Performance Level of PL c. Key technical parameters include an internal test rate of 13/s and a maximum demand rate of 8 min⁻¹. The mean probability of dangerous failure per hour (PFD) is rated at 6.6x10⁻⁹, supporting a mission time of 20 years. In the event of a fault, the system ensures that at least one Output Signal Switching Device (OSSD) enters an off state to maintain safety.

Feature Summary

• Provides reliable personnel protection through dual-channel monitoring and automatic self-diagnostic capabilities.
• Ensures immediate safe state activation by switching off output signals upon detection of faults or obstructions.
• Supports standardized integration into safety circuits via defined test rates and performance level compliance.

Applications

• Personnel protection zones around automated machinery
• Safety guarding for press brakes and stamping equipment
• Access monitoring for robotic work cells

Procurement Notes

Verify the specific resolution and protective height requirements against the machine safety design standards applicable in your region. Confirm compatibility with existing safety controllers regarding input types and wiring configurations. Ensure that the mounting accessories are included or ordered separately to guarantee proper alignment and stability during operation.

Selection Notes

Select this model based on the required safety category and performance level needed for the specific hazard analysis. Consider the environmental conditions such as ambient temperature and potential interference sources when determining the appropriate housing and lens configuration. Validate that the internal test rate aligns with the operational frequency of the protected machinery to ensure compliance with safety integrity limits.
