KH-A1251WF-02A线对板针座产品概述

一、产品基本定位与核心特征

KH-A1251WF-02A是金航标(kinghelm)推出的1.25mm间距卧贴式线对板针座,属于小间距高密度连接组件,核心配置为1排2Pin(1×2P)SMD封装,专为紧凑空间内的低压小电流信号/电力传输设计。其核心特征可概括为:小间距省空间、卧贴适配自动化生产、材料可靠耐环境,是消费电子、工业控制等领域小型化产品的理想连接方案。

二、关键性能参数深度解析

2.1 电气性能参数

  • 额定电流:1A(AC/DC),满足常规小型设备的信号传输及低功率电力供应需求(如传感器、小型电机控制);
  • 额定电压:125V(AC/DC),符合低压电气安全规范,避免高压击穿风险;
  • 触头接触电阻:基于黄铜+锡镀层的结构,行业常规≤20mΩ,确保信号传输无明显衰减。

2.2 机械与封装参数

  • 间距:1.25mm(比传统2.0mm/2.54mm间距缩小约50%,大幅节省PCB布局空间);
  • 封装形式:卧贴SMD(表面贴装),无需PCB通孔,适配自动化贴片生产线,提高生产效率;
  • 板上尺寸:Z轴高度3.2mm(垂直于PCB方向)、Y轴底边宽度5.15mm(平行于PCB方向),安装空间极小,适合超薄/小型化产品;
  • 总PIN数:2P(单排2Pin),结构简单,适配2芯排线连接。

2.3 环境与可靠性参数

  • 工作温度范围:-25℃+85℃,覆盖消费电子(-1060℃)及工业级(-20~85℃)常规温区,适应不同场景;
  • 塑料材质:PA46(聚酰胺46),熔点约295℃,可承受回流焊高温(常规回流焊峰值260℃),耐冲击、耐化学腐蚀;
  • 阻燃等级:UL94V-0(最高阻燃等级),燃烧时无滴落物,有效降低火灾风险,符合安全规范。

三、结构设计与材料选型优势

3.1 触头系统:稳定导电+耐氧化

  • 触头基材:黄铜(H65级),导电性优异(电阻率低),机械强度适中,不易变形;
  • 触头镀层:锡(Sn),成本可控且耐氧化性能好,避免长期使用中接触电阻增大,提升连接可靠性;
  • 插针结构:精准成型,与排线端子匹配度高,插拔力均匀(1~3N),减少接触不良概率。

3.2 塑料主体:耐温+阻燃+结构稳定

  • PA46材料优势:相比普通PA66,耐温更高(回流焊兼容性好)、尺寸稳定性更强(高温下变形小),确保贴装精度;
  • 一体化成型:塑料主体与触头精准定位,避免松动,提升机械稳定性;
  • 阻燃认证:UL94V-0,满足电子设备的安全阻燃要求,尤其适合消费电子、家电等场景。

3.3 卧贴封装:适配小型化与自动化

  • 无通孔设计:节省PCB背面空间,支持双面贴装,进一步提升PCB利用率;
  • 贴装高度低:3.2mm的Z轴高度,适合超薄产品(如智能手环、蓝牙耳机)的内部布局;
  • 自动化适配:SMD封装可通过贴片机批量生产,减少人工成本,提高生产一致性。

四、典型应用场景

KH-A1251WF-02A因小间距、卧贴、耐环境等特性,广泛应用于以下领域:

  1. 消费电子:智能手环、蓝牙耳机、遥控器、小型加湿器等产品的内部信号连接(如传感器与主控板、电池与主板);
  2. 工业控制:小型传感器模块(如温度/湿度传感器)、PLC辅助扩展板、微型电机控制板的排线连接;
  3. 通信终端:小型路由器、物联网终端(如智能门锁、环境监测节点)的内部数据传输;
  4. 家电领域:小型厨房电器(如榨汁机控制板)、智能家居设备(如智能灯泡控制器)的内部连接。

五、品牌与质量保障

金航标(kinghelm)作为国内专业电子元器件供应商,KH-A1251WF-02A具备以下质量保障:

  • 环保合规:符合RoHS标准,无铅、无镉等有害物质,满足欧盟及国内环保要求;
  • 可靠性测试:经过插拔寿命测试(≥500次)、温循测试(-25~85℃循环500次)、盐雾测试(48小时无腐蚀);
  • 认证齐全:UL94V-0阻燃认证,部分批次具备REACH认证,可满足不同客户的合规需求。

该产品凭借紧凑设计、可靠性能及成本优势,成为小型化电子设备连接方案的高性价比选择。

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
