KH-5224-8P8C是金航标(kinghelm)推出的带屏蔽直插式RJ45插座,专为以太网信号传输设计,采用8P8C(8针8槽)接口结构,兼容RJ45标准水晶头,兼顾抗干扰性与安装便捷性,适用于工业控制、智能家居等多场景。
该产品定位为高可靠性入门级以太网连接器,核心解决基础以太网(10/100M)传输中的信号抗干扰问题,同时满足低成本、易安装需求。主要适用场景包括:
因无内置LED指示灯,适合对指示灯无强制要求或需外置状态指示的设备设计,避免额外功耗与空间占用。
KH-5224-8P8C的参数符合以太网传输及工业应用的基本要求,核心参数如下:
参数类别 详细说明 接口类型 RJ45 8P8C(兼容TIA/EIA-568标准) 端口数量 1个独立RJ45端口 安装方式 直插式(DIP插件) 屏蔽特性 全金属屏蔽壳(含接地引脚) LED状态 无内置LED指示灯 传输性能 支持10/100M以太网传输 机械寿命 插拔次数≥1000次 电气参数 接触电阻≤20mΩ;绝缘电阻≥1000MΩ(500V DC);耐压≥500V AC(1min) 工作温度 -40℃~+85℃(工业级宽温) 环保认证 RoHS、REACH其中,-40℃~+85℃宽温范围是工业场景核心优势,可覆盖严寒户外或高温车间的稳定运行需求。
产品针对抗干扰、可靠性及安装便捷性做了针对性优化:
采用一体化金属屏蔽罩,覆盖插座主体及引脚区域,接地引脚与屏蔽壳直接导通,可有效抑制外界EMI/RFI电磁干扰(如电机、高频设备杂波),同时减少自身信号对外辐射,提升系统EMC兼容性。
接触针采用镀金(或镀锡)工艺,抗氧化性能优异,可确保长期(≥5年)传输无信号衰减;接触针排列严格遵循TIA/EIA-568A/B线序标准,支持直通/交叉线序切换,适配不同网络拓扑。
直插DIP引脚长度适配常规1.6mm厚度PCB,焊接时无需特殊工装,手工焊接或自动波峰焊均可;引脚间距符合PCB设计规范,避免相邻引脚短路风险。
采用PA66工程塑料壳体,阻燃等级V-0(UL94标准),耐冲击、耐老化,可承受10N机械应力不变形,适合工业振动场景。
为确保性能稳定,需注意以下要点:
KH-5224-8P8C由金航标(kinghelm)生产,该品牌是国内专注连接器研发的高新技术企业,产品覆盖通信、工业、汽车领域,通过ISO9001认证,符合RoHS环保标准。
产品经过多重可靠性测试:插拔寿命(1000次无故障)、高低温循环(-40℃+85℃,100循环)、振动测试(102000Hz,2g加速度),确保复杂环境稳定运行,已批量应用于国内多家工业控制及智能家居厂商。
总结:KH-5224-8P8C是一款性价比高、可靠性强的带屏蔽直插RJ45插座,适合对成本敏感但需稳定传输的以太网场景,尤其在工业自动化、智能家居领域具有广泛适配性。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
