SUNNY is a 20-year professional manufacturer specialized in designing and producing opto-electro-mechanical products.The company has a complete set of R&D equipment and instruments in terms of mechanism, sheetmetal, plastics, moulding, electric appliance, together with Surface Mounting Technology (SMT). We also provide you with a perfect technical support and after-sale services. SUNNY infrared elevator door protection system (light curtain) can identify, indicate and control each single light beam of the curtain under high speed scanning. SUNNY light curtain, with 64 pairs of diode inside, 192 beams and10 ms quick response time, is much safer and much more reliable than the product in the market, which ensure the safest protectionareaeven the door isnearly closed (door width is under300mm). Theproduct hasadvantages inspecificationas the table listed below,specially great in anti-interference like magnetism,sunlight and the extreme long detector distance, which always technically lead the Chinese market. SUNNY light curtain system obtained the National Invention Award of the People's Republic of China and has the national patent, No. 01105213.9. SUNNY is sole manufacture and supplier in China.ElevatorpartsTECHNICAL SPECIFICATIONS ModelSN-GM1-Z/O9192P Number of Diode64 Distance Between Diodes42mm middle/ 55mm side Maximum Beams192 Minimum Beams192 Highest Beam1800±50mm Lowest Beam17±5mm Size30(width) * 09 (thickness) * 1980mm (height) Detecting Distance0 4,000mm + 500mm (standard), 20,000mm for custmization Vertical displacement at 0 mm≤ ±20mm Horizontal displacement at 0 mm≤ ±10mm Angular displacement at 0 mm≤ ± 8° Cable reliablity3C passed three-core flexibility wire, tensile resistance < 15N, endure 1,000,000 time twist, length 4.5M ±10% Light immunity≥ 100,000 lux Immune to Sun Light and RefelectionYes EMC Compliance Emission to EN 12015 and Immunity to EN 12016 CE CompliancesYES UL CompliancesYes!
