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).

Dual Muting Function (DMB): The "DM" in the order code signifies built-in Dual Muting support. This allows for the safe, temporary suspension of the safety function via two independent sensor pairs (e.g., two light barriers) to enable automated materials to pass through the light curtain on a conveyor without triggering a machine stop, while personnel remain protected.

30 mm Resolution: The beams are spaced 30 mm apart. This resolution is ideal for perimeter guarding applications where the objective is to detect the presence of a hand or larger body part, balancing detection capability with operational practicality.

Long Sensing Range: Offers an extended standard range (up to 20 m), which can be increased 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, drastically simplifying installation, commissioning, 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 harsh environments involving dust, moisture, and vibrations.

4. Typical Applications

The LFP0700-A4DMB is specifically designed for applications requiring safe material flow through a guarded perimeter.

Conveyor Through-Fence guarding: Ideal for protecting points where a conveyor enters or exits a hazardous robotic or processing cell. The dual muting function allows pallets, boxes, or products to pass through without stopping production, while ensuring a person cannot enter.
