Connection structure and design details连接结构与设计要点
Circular interfaces concentrate the connections at the cable ends, with threaded coupling securing the mating position. Selection considers the interface keying, pin orientation, end dimensions and access needed to operate the coupling.圆形接口便于把接线点集中在电缆两端，螺纹连接用于固定插合位置。选配这类组件时，应同时考虑接口键位、针脚方向、端头长度以及锁紧操作所需空间。
Metal threaded coupling金属螺纹连接部位

APPLICATIONS连接的应用
Application directions应用方向
These are connection directions for project discussion. Suitability depends on interfaces, circuits, installation conditions and project validation; configuration can be adapted to the equipment.以下为可讨论的连接方向。实际适用性取决于接口、电路、安装环境和项目验证，可按设备需求调整。
Sensors and equipment modules传感器与设备模块连接
Use the corresponding M12 interface as the starting point. For sensors or equipment modules, configuration follows the device pin map and connection distance, with mating orientation and coupling access considered.对于采用对应M12接口的传感器或模块，可按设备针脚和接线距离配置连接线，兼顾插合方向与锁紧空间。
Control units and field interfaces控制单元与现场接口
Between a control unit and a field connection point, connector ends can define a removable connection boundary. Power, signal and shield paths follow the system definition. Match threaded, bayonet or push-pull coupling to operating clearance.在控制单元与现场连接点之间，可用两端插接结构规划可拆装的连接边界。电源、信号与屏蔽路径依据系统定义确认。选配时，螺纹、卡口或推拉锁紧配合安装操作空间。
Cable extensions and service access设备线缆延伸与维护
Where an interface needs to reach an accessible location, length and fixing routes can be adapted. Coding, pin mapping and clearance are confirmed for both ends. Match contacts with conductors, shield shells and wire seals.当接口需要延伸到便于操作的位置时，可按线长和固定路径调整组件。公母接口的编码、针脚对应与空间匹配需同时确认。选配时，接点与导体、屏蔽壳和线封成套匹配。
Industrial sensor distribution工业传感器分布连接
For distributed sensors, set cable lengths and exit directions from each connection point. Check the M12 series, keying and circuit definition against every device; interface diameter alone does not establish compatibility.设备上分布安装的传感器可按各接入点距离设置电缆长度与出线方向。M12接口系列、键位及电路定义须与设备逐一核对，不能仅按接口直径判定适配。
Equipment instrumentation and monitoring设备仪表与监测单元
For instruments and monitoring units, define signal or supply functions, routing distance and interference conditions before conductor, shield and termination selection. The illustrated form does not establish a sensor protocol.连接仪表与监测单元时，先确定信号或供电功能、允许走线距离及干扰环境，再确认导体、屏蔽和端接方案。图示结构不自动代表某种传感器协议。
Test and commissioning connections测试与设备调试连接
Prototype equipment and test fixtures can use removable connection boundaries for fit checks and replacement. Match the pin table, test-end definition and cable length to the equipment, then confirm continuity and assembly at the sample stage.样机或测试工装可采用可拆装的连接边界，方便安装验证与更换。针脚表、测试端定义及线长应与被测设备一致，并在样品阶段确认导通与装配。
