CONSTRUCTION结构解析
Connection structure and design details连接结构与设计要点
Use the 3-wire pressure sensor plug pigtail form as a starting point and confirm these design points against drawings and the actual equipment.以三线压力传感器插头尾线的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Pigtail connection form尾线连接形式
A lead section extends behind the connector, allowing length, further termination and support to follow the equipment connection.插接端后保留引线段，便于按设备接线位置确定长度、后续端接与支撑。
Trunk and branch layout主干与分支
Locate trunk and branch datums from equipment fixing points. Allow room for mating, bends and servicing so branches do not transfer installation loads to contacts.以设备固定点确定主干和各支路的尺寸基准，预留插拔、弯曲和维护空间，避免支路把拉力传递到端子。
Conductor and insulation selection导体与绝缘选配
Select conductors and insulation from circuit loads, diameter limits, bending and exposure. A material name does not replace ratings or validation results.从电路负载、外径限制、弯曲方式与环境条件选择导体和绝缘体系；材料名称不应直接代替额定参数或验证结果。
Interface and function review接口与功能确认
Distinguish PNP, NPN, voltage and current outputsPNP、NPN、电压与电流输出必须区别
