Key Features

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

14 mm Resolution: The beams are spaced 14 mm apart. This fine resolution is designed to detect fingers and small objects, providing a high level of protection for perimeter areas where closer access to hazards is possible.

Integrated Muting Function (NMC): The "M" signifies built-in Muting support. This allows for the safe, temporary suspension of the safety function via external sensors (e.g., two light barriers and a proximity sensor) to enable automated materials to pass through the light curtain on a conveyor without triggering a machine stop, while personnel remain protected.

Direct Cable Connection (NMC): The "C" indicates a fixed cable output instead of a standard M12 connector. This provides a more robust and vibration-resistant connection, reducing the risk of failure due to loose connectors, which is ideal for harsh industrial environments.

Long Sensing Range: Offers a long standard sensing range (up to 20 m), extendable to 70 meters using SICK reflectors (retroreflectors), allowing for flexibility in protecting large areas or complex machinery layouts.

Advanced Diagnostics: Comprehensive LED status indicators on both units provide instant visual feedback on alignment quality, power status, output state, and muting activity, simplifying 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 conditions involving dust, moisture, and vibrations.

4. Typical Applications

The LFP0600-A5NMC is designed for applications requiring fine resolution and reliable muting at perimeter access points.

Perimeter Guarding with Material Flow: Ideal for securing access gates and fences around robotic cells or presses where materials must pass through on a conveyor (using muting).

Packaging and Palletizing Lines: Guarding the perimeter around automated packaging machinery where both high-level hand detection and material muting are required.

Automated Assembly Stations: Protecting operators near assembly robots and automated equipment where precise detection is necessary.
