elevator light curtain UL,CE certification

SUNNY infrared elevator door protection system (light curtain) can identify, indicate and control each single light beam of the curtain under high speed scanning. When any beam fails to work properly, operator can identify the problem through a flashing lamp warning in the corresponding channel switch. By turning off the switch, the diodes in question will stop working, while the others diodes will continue to function normally. The elevator will be in normal operation condition without the need of urgent repair. The problem can be fixed during routine maintenance to minimize impact to the elevator users. SUNNY light curtains avoid the problem of traditional design, when any one of the beams is out of work the elevator will stop working. Some of the light curtains use timeout function to allow problem diodes to be ignored. This can extend the working life of the light curtain. However, with existing problem in system, the elevator is running in potential risk. 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). SUNNY light curtain 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.Elevator light curtain TECHNICAL SPECIFICATIONS ModelSN-GM1-Z/O9192H 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!
