Key Features

High Safety Integrity: Complies with IEC 61496-1/2 Type 4 standards, achieving 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 is designed to detect hands and larger body parts, making it ideal for perimeter guarding applications where the risk requires detection of significant body part access.

Muting Function Ready (NMB): The "M" indicates built-in Muting capability. This allows temporary, safe suspension of the safety function via external sensors to permit material passage through the protected area on conveyors without stopping production, while maintaining personnel protection.

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

Clear Visual Diagnostics: Powerful status and diagnostic LEDs on both emitter and receiver provide immediate feedback on alignment, power, output status, and faults for quick commissioning and troubleshooting.

Robust Construction: Features a durable aluminum housing with polycarbonate end caps and an IP65/IP67 protection rating, ensuring reliable operation in harsh industrial environments with dust, moisture, and vibrations.
