KH-MCX-KE-Z RF射频同轴连接器产品概述

一、产品核心定位与品牌背景

KH-MCX-KE-Z是金航标(Kinghelm)旗下MCX系列射频同轴连接器的核心型号,专为小体积、高频传输需求的电子设备设计,属于板端内孔型插件连接器。金航标作为国内射频连接器领域的专业厂商,MCX系列凭借小型化、高可靠、易安装的特点,广泛覆盖通信、物联网、便携式电子等领域;KH-MCX-KE-Z则是该系列中适配紧凑PCB布局的经典款,兼顾性能与成本优势。

二、基础参数与结构特征

该型号的核心参数及结构设计如下:

  • 基础规格:
    连接器类型为板端垂直安装,接口类型为内孔母头,端口数量1,接口直径4.8mm(符合MCX标准接口尺寸),接口高度4.5mm(安装后突出PCB表面的高度),引脚样式为正脚(垂直于PCB平面),封装为插件(通孔焊接)。
  • 性能参数:
    典型频率范围06GHz,驻波比(VSWR)≤1.2@DC-3GHz、≤1.5@3-6GHz,插入损耗(IL)≤0.15dB@DC-3GHz、≤0.25dB@3-6GHz,插拔寿命≥500次,工作温度范围-40℃+85℃(工业级标准)。
  • 结构设计:
    采用黄铜主体+镀金接触件,兼具导电性能与耐腐蚀性;内孔接口配合MCX公头实现快速插拔,正脚插件设计确保与PCB通孔精准对齐,焊接后连接牢固。

三、设计亮点与性能优势

  1. 小型化适配紧凑空间
    MCX接口尺寸仅4.8mm,比传统SMA接口缩小约30%,可适配智能手环、无线耳机等便携式设备的小PCB布局,同时满足工业传感器、物联网节点等小型化设备的安装需求。

  2. 高频传输稳定可靠
    针对0~6GHz频段优化设计,驻波比与插入损耗控制在行业领先水平,可满足蓝牙5.0、WiFi 6E、RFID等高频无线通信的传输要求,信号衰减小、失真度低。

  3. 安装便捷批量适配
    插件封装支持通孔焊接,无需特殊工具即可实现批量生产;正脚设计避免引脚弯折,焊接后连接牢固,适合自动化贴装产线的高效作业。

  4. 耐环境性能优异
    工作温度覆盖工业级范围,可在-40℃低温环境下稳定工作,同时具备抗振动、抗冲击能力,适配户外监控、车载电子等复杂场景。

四、典型应用场景

KH-MCX-KE-Z的应用场景覆盖多领域:

  1. 便携式电子设备:智能手环、无线耳机、手持POS机等小型无线终端的射频信号输入/输出接口。
  2. 物联网与工业控制:传感器节点、远程监控模块、工业网关等设备的无线通信接口,适配紧凑的设备内部空间。
  3. 通信模块:蓝牙模块、WiFi模块、NB-IoT模块等的板端射频接口,与外部天线实现可靠连接。
  4. 测试测量仪器:小型信号发生器、频谱分析仪、示波器等辅助测试设备的射频输入接口,满足高频测试需求。
  5. 医疗电子:小型医疗监测设备(如血糖监测仪、心率手环)的无线数据传输接口,确保信号稳定传输。

五、安装与适配说明

  1. 安装要求:

    • PCB板需预留直径0.8~1.0mm的通孔,引脚间距与焊盘对齐;
    • 焊接温度控制在260℃±10℃,单个引脚焊接时间≤3秒,避免高温损坏内部结构;
    • 焊接后清理助焊剂残留,防止腐蚀或影响电气性能。
  2. 适配公头:
    需搭配金航标MCX系列公头使用(如KH-MCX-JE),确保接口尺寸匹配,避免非原厂配件导致的连接松动或信号衰减。

  3. 注意事项:
    安装时避免过度弯折引脚,插拔公头需对准接口,防止内孔变形影响插拔寿命。

六、选型参考与注意事项

  1. 同系列选型对比:

    • 弯脚款:KH-MCX-KE-W(引脚平行于PCB,适合侧面安装);
    • 外牙公头款:KH-MCX-JE(外牙公头,配合内孔母头使用);
    • 带线款:KH-MCX-K-1.5(内孔母头带线,适合无需板端焊接的场景)。
  2. 使用注意事项:

    • 避免潮湿、多尘环境下长期裸露,建议配套防尘盖;
    • 插拔公头轻插轻拔,超500次寿命可能导致接触不良;
    • 存储于干燥环境(湿度≤60%),避免阳光直射或高温。

该型号凭借小型化、高可靠的特点,成为众多小型电子设备射频接口的优选方案,可满足不同场景下的高频传输需求。

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
