X4621FVS-2X20-C43D65 排母产品概述

一、产品核心定位与应用场景

X4621FVS-2X20-C43D65是中国星坤(XKB Connectivity)推出的2.0mm间距双排立贴方孔排母,专为高密度、小型化电子设备的信号与电源连接设计。产品采用SMD表面贴装工艺,适配自动化生产流程,可广泛覆盖以下场景:

  • 工业控制:PLC模块、传感器接口、小型伺服系统的板间连接;
  • 消费电子:智能家居设备、便携式医疗仪器、小型无人机的内部互联;
  • 通信终端:物联网网关、小型路由器的信号传输接口。

其2x20P(共40孔)的双排结构实现高密度连接,立贴安装方式大幅节省PCB垂直空间,契合当前电子设备“轻薄化”的设计趋势。

二、关键电气性能参数

产品核心电气指标平衡了性能与成本,满足常规中低功率电路的连接需求:

  • 额定电流:3A/孔(连续工作),可同时承载信号传输与小功率电源供应(单孔瞬时电流支持5A以上,需结合实际应用降额);
  • 额定电压:250V AC/DC,覆盖低压工业与民用电路的电压范围,无需额外绝缘设计;
  • 接触电阻:出厂测试≤10mΩ(镀金镀层保障长期稳定性),确保信号无损耗、电源压降在可接受范围。

这些参数适用于大多数非高压大功率的板间连接场景,无需额外降额设计(在额定范围内)。

三、机械结构与安装特性

产品机械设计聚焦“可靠性+空间效率”,核心特点如下:

  1. 间距与排数:2.0mm行业通用间距(兼容性强,可与同间距排针直接匹配),2x20P双排结构,总孔位数40,实现高密度连接;
  2. 安装方式:立贴(SMD),引脚采用表面贴装设计,适配回流焊工艺,自动化生产效率高,且无需PCB钻孔,节省板层空间;
  3. 插孔设计:顶部方孔,相比传统圆孔,接触面积提升约15%,插拔时接触点更稳定(不易偏移),同时方孔加工精度更高,连接一致性更好;
  4. 塑高尺寸:4.3mm低profile设计,大幅降低PCB垂直方向占用空间,适合小型化设备的紧凑布局(如厚度仅10mm的便携式仪器)。

四、材料与镀层的可靠性保障

产品从材料选型到镀层工艺均围绕“长期可靠连接”设计:

  • 触头材质:黄铜(H65),导电率约为纯铜的90%,兼具良好导电性能与机械加工性(不易变形);
  • 触头镀层:Au足1u(镀金厚度1微米),可有效抑制触头氧化、抗腐蚀(盐雾测试达48小时无明显氧化),同时降低接触电阻,提升插拔寿命(经测试≥500次插拔仍保持性能稳定);
  • 塑壳材质:耐高温工程塑料(PA6T/PBT),适配回流焊温度(260℃左右),耐冲击、抗老化,长期工作无开裂风险。

五、环境适应性与兼容性

产品环境适应性覆盖工业级与消费级场景:

  • 工作温度:-40℃~+105℃,可适应户外设备低温(北方冬季-20℃)与工业设备高温(电机旁+80℃);
  • 湿度耐受:镀金镀层配合工程塑料塑壳,可耐受95%RH(无凝露)环境,满足潮湿场景需求;
  • 兼容性:2.0mm间距、双排2x20P规格,与市场同参数排针(如星坤同系列排针)完全兼容,无需担心匹配问题。

六、品牌与封装说明

  • 品牌:XKB Connectivity(中国星坤),国内专业连接器制造商,产品覆盖汽车、工业、医疗等领域,质量体系通过ISO9001/TS16949认证;
  • 封装类型:SMD(表面贴装),引脚间距P=2mm,符合IPC标准,适配主流回流焊设备,生产过程可实现自动贴装、检测,一致性高。

该产品以“高密度、高可靠、易生产”为核心优势,是小型化电子设备板间连接的优选方案。

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
