The ESPE ESF Series is a waterproof safety light curtain designed for applications exposed to high humidity and underwater environments with IP68 protection rating, allowing reliable operation even when submerged in water. Its rugged construction with aluminum alloy and PMMA enclosure supports industrial installations in wash‑down areas, outdoor processing lines, wastewater systems, and other harsh environments where moisture and liquids are present. The series features short response time, low power consumption, and strong resistance to optical and electromagnetic interference to maintain dependable detection performance in demanding conditions.
The ESF Series also offers flexible beam spacing, resolutions, and protective heights to match different safety zones, with through‑beam sensing and wire synchronization providing stable detection even under fluctuating ambient light. With sensing distances typically up to approximately 4 m and extended options potentially measured underwater up to 5 m, it is suitable for guarding equipment where water exposure or high humidity would otherwise compromise conventional safety light curtains.
