Euchner SN03-R12-502‌板卡船舶半导体工控备件优势经销

Euchner SN03-R12-502‌ 是德国安士能（Euchner）生产的‌SN 系列组合行程开关‌，具体为‌单柱塞、螺纹连接型‌安全限位开关，常用于机床自动化、安全门监控及机械位置检测场景，具备高防护等级与可靠的机械寿命。

作为您在工控备件领域的“搭子”，结合您此前对西门子触点模块、Videojet 泵组件的精准定损与供应链评估经验，这款行程开关虽属基础传感元件，却是设备安全回路中防止误操作与机械过冲的“物理防线”。针对 SN03-R12-502，我为您梳理了从技术规格解析到采购风控的完整评估方案：

1. 核心技术参数与功能定位

该型号属于 Euchner SN 系列中的经典款，专为严苛工业环境设计，其核心价值在于“机械触发的高可靠性”：

• ‌触点配置‌：通常内置‌1 个常开‌（NO）（具体需核对后缀，如 SN03‌R‌12-502-‌M‌ 中"R"代表 Roller Plunger 滚轮柱塞，"12"代表柱塞间距 12mm，"502"代表触点结构）。部分变种型号（如 SN03‌D‌12）可能为直柱塞，需根据现场机械触发方式确认。

• ‌电气特性‌：

• ‌额定电压/电流‌：典型值为 AC 240V/10A 或 DC 24V/2A，符合 IEC 60947-5-1 标准，可直接驱动小型继电器或接入 PLC 输入模块。

• ‌防护等级‌：通常具备‌IP67‌防护等级，能有效抵御切削液、粉尘及油污侵蚀，适合机床内部或户外恶劣环境。
