The 11 - pin relay from Yueqing Huilong is a versatile industrial component designed for complex control circuits requiring multiple switching functions. This relay features an 11 - pin socket configuration (compatible with IEC 61131 - 2 standards), offering 8 contact points (4NO + 4NC) for flexible circuit design. The relay’s coil supports voltage options from 12V to 220V AC/DC, adapting to different power systems. Constructed with a nickel - plated brass base and polycarbonate housing, it withstands 50G vibrations and temperatures from - 40℃ to + 125℃. The silver - cadmium oxide contacts (16A/250V AC) provide high breaking capacity, while the built - in arc quenching mechanism reduces electrical noise. Ideal for elevator control panels, robotics, and building automation systems, the 11 - pin relay enables compact integration of multiple switching functions, simplifying circuit design and reducing panel space by 30%.
