HR903129A 屏蔽式RJ45插件插座产品概述

HR903129A是汉仁(HANRUN)推出的单端口屏蔽RJ45插件式以太网连接器,针对需要抗电磁干扰(EMI)的通信场景设计,兼顾传输稳定性与安装便利性,广泛适配工业控制、安防监控、网络设备等领域。

一、产品核心定位与应用场景

该产品定位于中低端可靠型以太网连接方案,核心解决普通非屏蔽RJ45插座在复杂电磁环境下信号衰减、干扰的问题,主要应用场景包括:

  • 工业自动化:PLC控制器、工业交换机、传感器节点的以太网接口;
  • 安防监控:网络摄像头、NVR硬盘录像机的有线连接;
  • 网络终端:路由器、交换机、智能家居网关的RJ45端口扩展;
  • 办公设备:打印机、一体机的有线网络接口。

二、关键性能参数与设计特点

1. 传输与电气性能

  • 支持10/100/1000BASE-T以太网传输,符合IEEE 802.3标准,兼容Cat5e/Cat6网线;
  • 接触电阻≤20mΩ(稳定接触,减少信号损耗);
  • 绝缘电阻≥1000MΩ(DC 500V,防止短路);
  • 耐压性能:AC 1000V/50Hz 1min无击穿、无飞弧。

2. 屏蔽设计优势

采用全金属屏蔽外壳,配合接地引脚设计,有效抑制外部电磁干扰(如电机、高频设备产生的EMI),同时减少自身信号对外辐射,提升系统抗干扰能力,适合工业车间、机房等电磁环境复杂场景。

3. 机械可靠性

  • 插拔寿命≥750次(符合行业通用标准,满足多次插拔需求);
  • 接触件采用高弹性磷青铜,表面镀金(50μinch),提升耐腐蚀性与接触稳定性,长期使用不易氧化;
  • 塑料主体采用耐高温ABS材料,焊接时不易变形。

三、结构与封装细节

1. 封装类型

插件式(DIP)封装,适配PCB板焊接安装,无需特殊工具,适合批量生产与人工焊接,安装效率高。

2. 结构组成

  • 金属屏蔽壳:包裹插座主体,提供EMI屏蔽;
  • 绝缘主体:ABS塑料,固定接触针与屏蔽壳,防止短路;
  • 接触针:8Pin镀金针脚,对应RJ45标准线序(T568A/B兼容);
  • 接地引脚:1Pin接地端,需焊接到PCB板地线上,确保屏蔽效果。

3. 尺寸规格

参考汉仁标准封装尺寸:长×宽×高≈15.5mm×10.2mm×8.3mm,符合行业通用PCB板布局,无需特殊板设计。

四、兼容性与可靠性验证

1. 兼容性

  • 兼容RJ45标准插头(Cat5e/Cat6),适配主流以太网设备;
  • 支持T568A与T568B两种线序,无需额外调整。

2. 可靠性测试

通过以下环境与性能测试,满足工业级使用要求:

  • 高低温循环:-40℃~85℃,循环50次,性能无衰减;
  • 湿热测试:60℃/95%RH,持续96h,无氧化、无短路;
  • 振动测试:10~2000Hz,加速度1G,持续2h,接触可靠;
  • 盐雾测试:5%NaCl溶液,持续48h,接触件无明显腐蚀。

3. 环保认证

符合RoHS 2.0标准,无铅、无镉、无汞等有害物质,满足欧盟环保要求。

五、安装与维护注意事项

1. 安装要点

  • 焊接温度:PCB板焊接时,烙铁温度控制在260℃±10℃,单个引脚焊接时间≤3s,避免过热损坏塑料主体;
  • 接地要求:屏蔽壳接地引脚必须可靠焊接到PCB板地线上,否则屏蔽效果失效;
  • 线序匹配:焊接网线时需确认T568A/B线序与插座针脚对应,避免信号错乱。

2. 日常维护

  • 定期检查插头插拔是否顺畅,若出现卡顿需清理端口灰尘;
  • 避免油污、液体进入端口,防止接触针氧化;
  • 若长期不使用,建议用防尘塞保护端口。

3. 注意事项

  • 不要在超过-40℃~85℃的环境下长期使用,避免性能衰减;
  • 禁止用尖锐物体刮擦接触针或屏蔽壳,防止损坏。

该产品以高性价比、稳定可靠的特点,成为工业与消费电子领域以太网连接的常用选择,适配多种场景下的抗干扰通信需求。

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
