Phoenix Contact 1803303 插拔式接线端子产品概述

一、产品基本信息

Phoenix Contact(菲尼克斯)1803303为工业级插拔式接线端子,属于板端/插座-闭口类型,核心结构为1排5针(1×5P),针脚间距3.81mm,外壳采用绿色绝缘材料,安装方式为弯针焊接,总PIN数5P,单排针脚数5P。该产品专为PCB板与外部电路的快速可靠连接设计,是菲尼克斯工业连接体系中的经典紧凑型端子之一。

二、核心性能参数

1803303的核心电气与环境参数符合工业设备的严苛要求:

  • 额定电流:8A(环境温度25℃时的连续载流能力,温度升高时需降额使用);
  • 额定电压:160V(AC/DC通用,满足低压控制与信号传输需求);
  • 接触电阻:典型值≤10mΩ(优质铜合金接触件确保低损耗、高稳定性);
  • 绝缘电阻:≥1000MΩ(25℃、500V DC条件下,防止漏电与信号干扰);
  • 工作温度范围:-40℃~+120℃(适应极端工业环境,如低温车间、高温设备舱);
  • 认证:符合IEC 60947-7-1、UL 1059、VDE 0611等国际标准,可直接用于出口设备。

三、设计与结构特点

该端子针对工业场景的可靠性与易用性优化,关键设计亮点包括:

1. 闭口式插座设计

插座采用封闭结构,可有效阻挡灰尘、油污、金属碎屑等异物进入,避免接触件氧化或短路,提升长期使用的可靠性,尤其适合粉尘较多的工厂车间、户外机柜等环境。

2. 弯针安装结构

弯针设计(90°针脚)可实现PCB板的垂直/侧面安装,节省设备内部空间,适配紧凑布局的工业控制板(如PLC模块、伺服驱动器)。针脚采用镀锡处理,焊接性优异,减少虚焊风险。

3. 3.81mm标准间距

3.81mm是工业接线端子的通用间距之一,与菲尼克斯同系列插头(如MC 1.5/5-G-3.81)完全兼容,同时可适配第三方同间距插头,降低系统集成成本。

4. 绿色外壳标识

绿色外壳不仅便于设备内部的颜色编码管理(如区分电源、信号回路),还采用阻燃等级UL94 V-0的聚酰胺材料,防火性能优异,符合工业设备的安全规范。

5. 插拔式快速连接

无需专用工具即可实现插头与插座的快速插拔,插拔次数可达500次以上,便于设备调试、维护或模块更换,提升现场工作效率。

四、典型应用场景

1803303因紧凑结构与高可靠性,广泛应用于以下工业领域:

  • 工业自动化:PLC输入/输出(I/O)模块、伺服驱动器编码器接口、传感器信号转接板;
  • 电力电子:开关电源模块、变频器控制板、逆变器信号接口;
  • 新能源:充电桩控制板、储能系统BMS(电池管理系统)辅助连接;
  • 通信设备:基站辅助电源接口、路由器/交换机的信号转接;
  • 医疗设备:诊断仪器(如监护仪)的内部连接(需配合医疗级导线使用)。

五、安装与使用注意事项

为确保端子性能与设备安全,使用时需注意:

  1. 焊接前确认:PCB板焊盘尺寸需与弯针直径匹配(φ1.0mm左右),焊接温度控制在260℃以内(持续时间≤3秒),避免损坏绝缘外壳;
  2. 导线匹配:接线时选择截面积≤0.75mm²的软/硬导线(对应8A载流能力),剥线长度控制在6~7mm,确保接触可靠;
  3. 插拔规范:插拔时需垂直于PCB板方向施力,避免斜向拉扯导致针脚变形;
  4. 环境防护:长期暴露在潮湿环境时,需配合密封胶圈或防护外壳使用,防止端子受潮;
  5. 定期检查:每6个月检查一次接触电阻与针脚焊接状态,防止松动或氧化导致接触不良。

六、品牌与品质优势

作为菲尼克斯的核心工业端子产品,1803303依托品牌优势具备以下核心竞争力:

  • 百年品牌沉淀:菲尼克斯专注工业连接技术70余年,产品覆盖全球100+国家和地区;
  • 严苛质量管控:每批次端子均经过振动测试(10Hz~2000Hz,加速度10g)、冲击测试(100g,11ms),确保适应工业现场的振动与冲击;
  • 全生命周期支持:提供技术手册、安装视频等资源,以及全球售后网络,解决客户使用中的问题。

综上,Phoenix Contact 1803303是一款兼顾紧凑性、可靠性与易用性的工业级插拔式端子,可满足多数低压工业设备的连接需求,是工业自动化、电力电子等领域的优选组件。

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.
