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.
The SN-GDC-3 type photoelectric switch, developed and manufactured by Shanghai Sunny Elevator Co.,Ltd, adopts infrared detection technology to make the response time in microsecond class. The product is widely used in elevator car leveling detection and other opaque strip detection. When any obstacle blocks the infrared light beam, the indicator light will light up, while the output signal tells linkage part to do relative automatic control action.
The SN-GDC-3 photoelectric switch has some features such as wide range of operation voltage, protection of power polarity, strong anti-jamming ability. The product adopts hermetic structure to be impeccable in IP protection class such as lightproof, waterproof, dustproof and diamagnetism. Output signal has two choices of PNP and NPN.
