KH-A2508-02AB 2.5mm间距1x2P立贴排针产品概述

一、产品定位与核心身份

KH-A2508-02AB是金航标(kinghelm) 旗下一款紧凑型表面贴装(立贴)排针,采用1排2针(1x2P) 结构,间距2.5mm。作为小型化连接器件,它聚焦「高密度PCB布局+稳定电性能」需求,替代传统插件排针,适配对尺寸敏感且需可靠电流/信号传输的电子设备,是消费电子、工业控制等领域的实用型连接方案。

二、关键性能参数解析

1. 电性能:兼顾功率与安全

  • 额定电流:3A(AC/DC通用),优于同间距常规排针(多为1A),可直接支撑小型电机、传感器模块的供电需求,无需并联多针;
  • 额定电压:250V,满足家电、工业控制的低压电路规范,避免过压风险;
  • 接触电阻:稳定在10mΩ以内,降低信号传输损耗,保证数据/电源传输精度。

2. 环境适应性:宽温+阻燃双保障

  • 工作温度:-25℃~+85℃,覆盖常规室内外场景(如智能家居冬季低温、工业模块夏季高温),无结露或高温变形失效;
  • 阻燃等级:UL94V-0,塑料主体燃烧时自熄且无滴落,符合电子设备安全规范,降低火灾隐患。

三、材料工艺的可靠性设计

1. 触头系统:导电+焊接双优

  • 基材:黄铜(H62牌号),导电率≥28%IACS,接触稳定性强;
  • 镀层:3~5μm锡层,兼顾抗氧化性(长期使用无氧化层堆积)与焊接兼容性(适配无铅回流焊,无需特殊工艺)。

2. 塑料主体:耐温+耐冲击双强

  • 材质:PA6T(聚对苯二甲酰己二胺),耐温达260℃(高于常规PA66的220℃),可承受回流焊峰值温度(240~250℃)不变形;
  • 特性:耐冲击、耐化学腐蚀,适配工业环境的油污/溶剂接触,延长产品寿命。

3. 结构工艺:立贴+一体成型

  • 立贴设计:针脚折弯+表面焊盘结构,适配自动化SMT贴装,无需手工插件,生产效率提升30%以上;
  • 一体成型:针脚与塑料主体注塑结合,无松动风险,避免长期使用中触头偏移。

四、安装与尺寸适配性

1. 安装方式:高效易产

  • 表面贴装(立贴),符合IPC标准焊盘设计,焊接良率≥99.5%;
  • 适配0.8~1.6mm厚度PCB,覆盖常规电路板规格。

2. 尺寸规格:紧凑适配小空间

项目 参数 适配优势 总PIN数 2P 简化单路信号/电源连接 排数/每排PIN数 1排×2P 布局紧凑 间距 2.5mm(标准间距) 可与同规格接插件(如KH-A2508-02AF母座)配对,兼容性强 板上高度(Z轴) 9.5mm 不占垂直空间,适合小型设备 板上宽度(Y轴) 10.4mm 平行PCB方向占用小,适配窄板

五、典型应用场景梳理

  1. 智能穿戴设备:智能手环、手表的传感器(心率、加速度)与主板连接——尺寸紧凑不占空间,3A电流满足传感器供电;
  2. 小型工业控制:PLC扩展模块、温湿度传感器节点的信号传输——阻燃V-0符合工业安全,PA6T耐冲击;
  3. 家电控制板:加湿器、智能插座、小型净化器的内部连接——250V电压适配家电规范,3A电流支撑电机运行;
  4. 消费电子配件:移动电源输出接口扩展、蓝牙音箱内部连接——立贴安装适合批量生产,镀锡触头长期稳定。

总结

KH-A2508-02AB以「小尺寸、高可靠、易生产」为核心优势,覆盖多场景电子设备的连接需求,是金航标在小型化排针领域的高性价比产品。

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
