本标准定义:连接器系统的整体结构；连接器插座的物理尺寸；指定触点分配和产生的流向的插入配置；连接器系统的性能要求。本设计标准鼓励集成式电子液压比例定向阀的最终用户使用能够安全实现接口和互换性的连接器。本标准不影响阀门的液压机械设计，除了指令输入、感觉和大小与合成流方向之间的隐含关系。 提供了两类性能要求:在遇到常用工业液压油的环境中的兼容性；在遇到更具攻击性的液压油的环境中的兼容性。

This standard defines:the overall structure of the connector system;the physical dimensions of the connector receptacle;the insert configuration specifying contact assignment and resulting flow direction;the performance requirements of the connector system.This design standard encourages end users of integrated electronic hydraulic proportional directional valves to use a connector that will safely enable interfacing and interchangeability. This standard does not influence the hydromechanical design of the valve other than the implied relationship of the command input, sense and magnitude to the direction of resultant flow.Two classes of performance requirements are provided:compatibility in environments that encounter the commonly used industrial hydraulic fluids;compatibility in environments that encounter more aggressive hydraulic fluids.
