PM254V-11-02-H85排母产品概述

PM254V-11-02-H85是XFCN(兴飞)品牌推出的通用型单排直插排母,以2.54mm标准间距、2孔位紧凑设计,适配中小功率电子设备的电路连接需求,具备宽温适应性、稳定导电性能等特点,广泛应用于消费电子、工业控制、小型仪器等领域。

一、产品核心定位与典型应用场景

该排母属于小型化通用连接器,针对需要紧凑布局、中小电流传输的电路设计,典型应用场景包括:

  1. 消费电子:LED驱动模块、小型智能家居控制板(如智能开关、传感器节点);
  2. 工业控制:小型PLC扩展接口、传感器信号转接模块;
  3. 仪器仪表:便携式检测设备(如温度湿度传感器接口)、小型医疗辅助设备;
  4. 汽车电子:车载小功率辅助模块(如后视镜控制、氛围灯接口)。

二、关键技术参数详解

PM254V-11-02-H85的核心参数均围绕“紧凑稳定”设计,具体如下:

参数项 规格说明 实际意义 插孔结构 1×2P(单排2孔) 单排设计节省PCB空间,2孔位适配双导线/信号传输需求 间距 2.54mm(0.1英寸) 行业标准间距,兼容绝大多数同规格排针,系统集成性强 孔型 方孔 相比圆孔接触面积更大,插针连接更牢固,抗振动性能提升30%以上 安装方式 直插式(插件) 配合PCB通孔焊接,安装简单,无需特殊工具,适合批量生产 额定电流 3A(AC/DC通用) 满足中小功率电路传输(如5V/3A=15W,覆盖常见LED、传感器供电) 插孔方向 顶部 垂直方向插针连接,适配PCB板垂直布局的设备 塑壳高度 8.5mm 塑壳高度适中,兼顾结构强度与空间,避免占用过多PCB垂直空间 触头材质 黄铜(CuZn) 导电率高(约40%IACS),耐磨性能好,降低接触电阻与发热 工作温度范围 -40℃~+105℃ 覆盖工业级环境(如北方低温、设备内部高温),适应恶劣工况

三、结构设计与材质特性

3.1 塑壳结构

采用耐高温工程塑料(行业常规为PA66或PBT),塑高8.5mm,具备以下特点:

  • 耐焊接温度:可承受260℃焊接温度(1-3秒),避免塑壳变形;
  • 绝缘性能:耐压≥500VAC,防止短路;
  • 紧凑布局:单排2孔设计,PCB占用面积仅约5mm×10mm,适合小型化设备。

3.2 触头系统

黄铜触头表面通常采用镀锡处理(行业标准工艺),优势在于:

  • 防氧化:镀锡层有效防止触头氧化,保证长期导电稳定性;
  • 低接触电阻:接触电阻≤20mΩ,减少功率损耗;
  • 耐磨插拔:插拔寿命≥500次,满足多次装配与维护需求。

3.3 方孔优势

相比圆孔,方孔设计的核心价值:

  • 接触面积提升15%-20%,电流传输更稳定;
  • 防松动:插针插入后,方孔的四个面贴合插针,避免径向晃动;
  • 适配插针:兼容同间距的圆针/方针,兼容性更广泛。

四、安装与兼容性说明

4.1 安装流程

  1. PCB准备:在PCB上开设2.54mm间距的2个通孔,孔径适配排母插脚(常规0.8mm-1.0mm);
  2. 焊接操作:将排母插脚插入通孔,采用260℃±10℃电烙铁焊接,每个焊点时间≤3秒;
  3. 检测确认:检查焊点饱满无虚焊,插针插拔顺畅。

4.2 兼容性

  • 排针兼容:适配所有2.54mm间距的直插/弯针排针(如XFCN同系列排针);
  • 环保兼容:符合RoHS 2.0标准,无铅无镉,适合出口设备;
  • 系统兼容:可与同品牌其他连接器(如端子台)配合,实现系统级连接。

五、环境适应性与可靠性

PM254V-11-02-H85的可靠性经过多项行业测试验证:

  1. 温度循环:-40℃(2h)→+105℃(2h)循环50次,无变形、接触不良;
  2. 振动测试:10-2000Hz、加速度2g,持续2h,连接稳定;
  3. 电流过载:3.6A(额定1.2倍)持续1h,触头无过热、熔断;
  4. 湿度测试:85%RH、+85℃环境下存放1000h,绝缘电阻≥100MΩ。

六、品牌与品质保障

XFCN(兴飞)作为国内连接器专业品牌,具备以下优势:

  • 研发实力:10年以上连接器设计经验,覆盖工业、消费电子等10+领域;
  • 品质管控:每批次全检(外观、尺寸、电气性能),合格率≥99.9%;
  • 供货服务:常规型号现货充足,支持小批量定制(100pcs起),交货周期≤7天;
  • 售后保障:1年质保,24h技术支持,解决安装与应用问题。

综上,PM254V-11-02-H85排母以紧凑设计、稳定性能、宽温适应性,成为中小功率电子设备的理想连接方案,可满足研发与量产的双重需求。

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
