SICK LGSE220-33 Optic Electronic Light Safety Curtain Barrier

The SICK LGSE220-33 is a compact optic electronic light safety curtain barrier designed for industrial machine guarding and personnel protection. This device functions as part of a safety light grid system, typically consisting of a sender and receiver unit (though the provided images show a single unit, likely the emitter or receiver). It utilizes infrared beams to detect intrusions into hazardous areas, triggering machine stops to prevent accidents. Key applications include safeguarding presses, robots, and conveyor systems in manufacturing environments. Features include high-resolution detection with a 30mm beam resolution (inferred from model suffix), robust yellow housing for visibility, and IP65-rated enclosure for dust and water resistance. Advantages over similar products include reliable performance in harsh industrial settings, easy integration with control systems via standard interfaces, and compliance with safety standards like EN ISO 13849-1. Benefits encompass enhanced worker safety, reduced downtime from false triggers, and modular design for flexible installation. Drawbacks may include the need for paired units (sender/receiver) for full functionality and potential sensitivity to alignment issues in vibrating environments. Based on image analysis, this unit appears used but in good condition, with minor surface wear and intact labels. No parent/child assets are visible. For detailed specs, refer to SICK's official datasheets (e.g., via sick.com search for LGSE series). Estimated market price for a used unit is $400-600 USD, based on comparable eBay and industrial surplus listings.
