1068148

Overview

The SICK model 1068148 is a safety light curtain from the M2000 series, designed for personnel protection in industrial environments. It operates as a Type 2 safety device according to IEC 61496-1 with a Safety Integrity Level (SIL) of 1 per IEC 61508 and Performance Level PL c under EN ISO 13849. The unit features an internal test rate of 13/s and supports a maximum demand rate of 8 min⁻¹. Its mean probability of dangerous failure per hour (PFHd) is 6.6x10⁻⁹, with a mission time (TM) rated at 20 years. The system ensures a safe state by maintaining at least one OSSD in the off position during faults.

Feature Summary

• Provides personnel protection through safety light curtain technology compliant with international safety standards.
• Features a robust mechanical shell with a unit weight of 1.356 kilograms for stable installation.
• Ensures functional safety by automatically entering a safe state upon detection of faults.
