The SICK LFP0530-A5NMC is a Type 4 (Category 4 according to IEC 61496-1/2) . It creates an invisible infrared protective field around hazardous areas. When this beam array is interrupted, the device sends a stop signal to the machine's safety control system, initiating a protective stop to prevent injury.
Key Features
High Safety Integrity: Meets Type 4 / Category 4 standards, providing a high level of performance and safety for applications requiring Performance Level e (PL e) according to ISO 13849-1 or SIL 3 according to IEC 62061.
Cost-Optimized Solution: Part of the "Inexpensive Protection" series, offering essential safety light curtain functionality at a competitive price point for standard applications.
Extended Protective Field: Provides a taller 530 mm protective field height, suitable for safeguarding larger access points where more than just hand detection is required.
Standard Resolution: The 30 mm beam resolution (spacing between beams) is designed for hand detection, preventing access to danger zones.
Fixed Blanking Function: Allows for the permanent masking of one or two beams to accommodate for fixed obstructions within the protective field (e.g., a machine column or support post) without compromising the overall safety function.
Simple Alignment: Integrated alignment LEDs on both the transmitter and receiver units simplify installation and commissioning.
Daisy-Chaining Capability: Multiple LFP units can be connected in series from a single power supply, reducing wiring complexity and cost for systems with multiple guarded zones.

5. Typical Applications
The LFP0530-A5NMC is ideal for safeguarding larger access points on machinery where a 30mm resolution is sufficient:
Packaging Machinery: Guarding access doors or feeding points.
Assembly Stations: Protecting operators at semi-automated work cells.
Material Handling: Safeguarding the perimeter of conveyor systems or robotic palletizers.
Plastic Processing Machinery: Guarding access to injection molding machines.
