Key Features

Compact Design: With a protective height of only 300 mm, this light curtain is ideal for applications with limited mounting space or for protecting smaller access points and hazardous zones.

High Safety Integrity: Certified to IEC 61496-1/2 Type 4 standards, achieving the highest safety ratings: Performance Level (PL) e (ISO 13849-1) and Safety Integrity Level (SIL 3) (IEC 62061).

30 mm Resolution: The beams are spaced 30 mm apart. This resolution effectively detects hands and larger body parts, providing reliable protection for perimeter guarding and access control applications.

Muting Function Ready (NMB): The "M" indicates built-in Muting capability. This allows for the safe, temporary suspension of the safety function via external sensors to enable automated materials to pass through the protected area on conveyors without triggering a machine stop, while maintaining personnel protection.

Extended Sensing Range: Offers a standard sensing range of 0.5 to 20 meters, extendable to 70 meters using SICK reflectors (retroreflectors), providing flexibility for various application layouts and mounting configurations.

Advanced Diagnostics: Comprehensive LED status indicators on both emitter and receiver units provide instant visual feedback on alignment quality, power status, output state, and muting activity, facilitating easy installation and troubleshooting.

Robust Industrial Design: Constructed with a durable aluminum housing and polycarbonate end caps, featuring a high IP65/IP67 protection rating for reliable performance in demanding industrial environments involving dust, moisture, and vibrations.
