The SQX-3B type is mainly used for double point lifting mechanisms such as main and auxiliary hook cranes, gate opening and closing machines. Its feature is a combination of dual sensors, dual channel input, and separate display and control outputs. Sensors can be combined in various forms such as bearing seat type (SQX), fixed sliding wheel type (HLQX-3), and shaft pin type (XZ).
