Industrial 5502WR Industrial Safety Light Curtain

The SIEI 5502WR Industrial Safety Light Curtain is an electro‑optical protective device designed to guard access points around hazardous machinery in industrial environments. This two‑unit system comprises a transmitter and receiver that project an array of infrared beams to form a protective curtain across an opening. When any beam is interrupted by a person or moving object, the receiver immediately signals the connected safety controller to stop the machine, helping to prevent injuries during operation and maintenance tasks. The 5502WR is intended for integration into standard safety circuits and is suitable for guarding openings in equipment such as presses, cutters, and robotic work cells, where fast, reliable detection of entry is crucial. The model sits within SIEI’s line of light curtains and supports typical safety configurations used in industrial automation. For buyers, the key considerations are ensuring compatibility with your safety PLC or safety controller, confirming the required number of beams and sensing range from the official datasheet, and aligning with your risk assessment and compliance demands. When selecting this unit, verify electrical connections, output type, and mounting options described by the manufacturer to ensure a proper fit in your line‑side guarding setup.
