PM254V-11-04-H85 排母产品概述

PM254V-11-04-H85是兴飞(XFCN)品牌推出的一款单排直插式排母,采用行业通用的2.54mm间距设计,以高兼容性、可靠性能和经济实用性为核心,适配多数小型电子设备的板间信号/电源连接需求。

一、产品核心定位与典型应用场景

该排母属于基础型插件排母,结构紧凑(1×4P单排),专为小尺寸PCB布局设计,典型应用覆盖三大领域:

  1. 消费电子与智能家居:如小型智能控制器(温控器、灯控模块)、便携式音频设备的板间连接;
  2. 工业控制与监测:工业传感器模块、小型PLC辅助模块的信号传输;
  3. 单片机与开发板:Arduino、STM32等开发板的扩展接口,满足原型开发与批量生产的一致性需求。

二、关键参数详细解析

1. 结构参数

  • 布局与间距:单排1×4P设计,2.54mm标准间距(符合IEC 60947-5-2行业规范),适配绝大多数同间距排针;
  • 插孔与安装:顶部方孔设计(接触面积较圆孔提升约15%),直插插件式安装(引脚长度适配1.6mm标准PCB),塑高8.5mm(兼顾空间紧凑性与焊接操作空间);
  • 总孔位数:4P单排,支持多路并行信号或低功率电源传输。

2. 电气参数

  • 额定电流:单孔3A(总电流≤12A),满足小功率电源(如5V/12V)或中等频率信号(≤10MHz)传输需求;
  • 触头材质:黄铜(CuZn37),导电率≥28%IACS,比铁基触头更耐氧化,比铜合金更具成本优势。

3. 环境参数

  • 工作温度:-40℃~+105℃(宽温范围),适配工业级低温(如北方户外设备)、高温(如车载辅助模块)环境;
  • 存储温度:-55℃~+125℃(满足极端环境下的运输存储)。

三、核心性能优势

1. 高兼容性与通用性

2.54mm间距为行业通用规格,无需特殊定制即可匹配主流排针(如XFCN同系列排针),降低研发与采购成本;单排4P结构可灵活组合(如2个并联为8P),适配不同需求。

2. 接触可靠性

方孔设计增加触头与排针的接触面积,初始接触电阻≤10mΩ,长期使用无明显衰减;黄铜触头表面经镀锡处理(可选),进一步提升抗氧化能力,减少信号干扰。

3. 安装便捷性

直插插件式无需贴片设备,人工焊接或自动焊锡均可;塑高8.5mm提供足够的焊接空间,避免引脚与塑壳粘连,批量生产虚焊率≤0.1%。

四、工艺与材质保障

1. 塑壳工艺

采用耐高温PBT工程塑料(UL94 V-0阻燃等级),注塑成型精度±0.03mm,插孔定位准确(错位≤0.02mm);塑壳表面光滑无毛刺,插拔力均匀(25~45N),避免卡滞。

2. 触头工艺

黄铜触头经精密冲制+去毛刺处理,尺寸公差±0.05mm;表面可选镀锡(厚度≥2μm),满足无铅焊接要求,符合RoHS环保标准。

五、安装与适配注意事项

  1. 焊接规范:焊接温度260℃±5℃,单引脚焊接时间≤3秒(避免塑壳受热变形);推荐使用直径0.8mm焊锡丝;
  2. 插拔维护:避免斜向插拔(防止触头变形),长期使用后可定期用酒精棉清洁插孔(去除轻微氧化层);
  3. 振动环境适配:若用于振动场景(如车载),可在PCB上预留固定孔,配合尼龙扎带或螺丝固定排母。

六、可靠性验证

该产品通过多项标准测试:

  • 温湿度循环:-40℃(2h)→+105℃(2h)循环50次,性能无衰减;
  • 插拔寿命:≥500次插拔后,接触电阻变化≤5mΩ;
  • 阻燃测试:UL94 V-0级,遇火自熄(燃烧时间≤10秒)。

总结

PM254V-11-04-H85作为兴飞品牌的基础型直插排母,以标准规格、可靠性能和高性价比,成为小型电子设备板间连接的实用选型,覆盖消费电子、工业控制等多领域需求。

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
