Phoenix Contact 1803426 插拔式接线端子产品概述

一、产品核心身份与定位

Phoenix Contact(菲尼克斯)1803426是一款工业级单排插拔式板端端子,属于品牌3.81mm标准间距系列的基础款。其主打“紧凑结构+可靠传输”,适配中小功率电气设备的PCB板端信号/功率连接,需配合对应线端端子(如MC系列)实现插拔功能,是工业自动化、电力控制等领域的常用基础组件。

二、基础参数与结构特征

该端子的核心参数清晰匹配工业场景需求:

  • 结构规格:单排(1排)2针(2P),闭口式设计(针脚完全隐藏于外壳内);
  • 安装方式:直针插件(DIP),直接焊接于PCB板;
  • 电气性能:额定电流8A(AC/DC通用),额定电压160V(满足低压配电绝缘要求);
  • 物理特性:间距3.81mm(工业标准间距,兼容性强),外壳绿色(易识别,区分信号/功率回路);
  • 材料特性:绝缘外壳采用阻燃聚酰胺(PA),符合UL94 V-0阻燃等级;接触件为铜合金(磷青铜),表面镀锡提升导电性与抗腐蚀。

三、设计优势与性能亮点

  1. 安全防护:闭口设计降低风险
    针脚无外露,避免安装/维护时误触短路,同时减少灰尘、油污侵入,延长端子寿命;
  2. 可靠接触:低阻传输减少发热
    接触件采用菲尼克斯专利压接结构,插拔时接触压力稳定,接触电阻≤10mΩ,可有效避免大电流下的发热问题;
  3. 安装便捷:适配常规PCB工艺
    直针插件设计兼容标准回流焊/波峰焊,焊接后定位牢固;2P紧凑结构节省PCB空间,适合高密度布局;
  4. 宽温耐候:适应工业环境
    工作温度范围-40℃~+105℃,可满足北方低温、南方高温的工业现场需求;
  5. 认证齐全:符合国际标准
    产品通过UL、CE等认证,适用于全球范围内的工业设备设计。

四、典型应用场景

  1. 工业自动化控制:PLC输入输出模块(I/O)接线、传感器(光电/接近/温度)与控制器的连接;
  2. 小型电力设备:变频器辅助电源、伺服驱动器控制回路、低压配电盘接线;
  3. 通信与网络:基站电源模块、工业交换机信号接口;
  4. 智能家居/楼宇控制:智能照明控制器、安防系统接线端子;
  5. 医疗设备(非侵入式):小型诊断设备(如体温计、血氧仪)的信号传输接口。

五、安装与维护注意事项

  1. 焊接规范:焊接温度≤260℃,时间≤3秒,避免高温损坏绝缘外壳;焊接后需清洁助焊剂残留;
  2. 插拔操作:仅配合菲尼克斯对应线端端子(如MC 1.5/2-ST-3.81)使用,插拔时垂直用力,避免针脚弯曲;
  3. 环境防护:避免安装在潮湿、腐蚀性气体(硫化氢/氯气)环境,户外使用需额外加防护盒;
  4. 定期检查:每半年检查接触电阻(正常≤10mΩ),若针脚氧化可用无水酒精清洁。

六、选型与替代参考

  • 同系列扩展:若需更多针数,可选择1803427(1x3P)、1803428(1x4P),间距与电气参数一致;
  • 电流升级:需16A电流时,可替换为菲尼克斯1803500系列(3.81mm间距,16A额定);
  • 间距调整:空间允许时,2.54mm间距端子(如1786705)可作为紧凑替代,但电流能力降至3A。

综上,1803426以“紧凑可靠、安装便捷”为核心优势,覆盖了工业领域中小功率设备的基础接线需求,是菲尼克斯3.81mm系列中性价比突出的经典型号。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
