KH-2.54FH-1X16P-H8.5 单排直插方孔排母产品概述

一、产品定位与核心参数

KH-2.54FH-1X16P-H8.5是金航标(Kinghelm)针对信号传输+小功率电源传输场景推出的工业级单排直插方孔排母,主打“紧凑空间适配+稳定接触”核心优势,可覆盖消费电子、工业控制等多领域需求。其核心参数清晰明确:

  • 机械规格:1排16个插孔(1×16P),行业标准2.54mm间距,顶部方孔结构,直插式插件封装,塑壳高度8.5mm;
  • 电气规格:额定电流3A(AC/DC通用),额定电压250V(AC/DC),接触电阻≤20mΩ(典型值);
  • 环境规格:工作温度覆盖-40℃+105℃,存储温度-55℃+125℃,满足工业级温区要求;
  • 材质基础:塑壳采用耐高温PBT(耐温120℃以上),端子为高导电黄铜(可选镀锡/镀金镀层)。

二、结构设计与工艺特点

该排母的结构设计围绕“稳定接触+安装便捷”展开,核心工艺优势显著:

1. 方孔插孔的实用价值

对比传统圆孔,方孔与排针的接触面积增加约15%,插拔力分布更均匀(波动≤±0.5N),能有效降低接触电阻波动(插拔后变化≤5mΩ),减少发热风险;同时方孔的抗磨损能力更强,典型插拔循环寿命≥500次,远超行业普通圆孔排母(300次左右)。

2. 直插安装的适配性

塑高8.5mm精准适配1.6mm标准PCB厚度,端子伸出长度(约2mm)合理,焊接时焊锡浸润性好,可避免假焊;单排结构节省PCB空间(占用宽度仅约2.54mm×16+间隙),适合智能家居、小型工业模块等紧凑布局场景。

3. 塑壳与端子的工艺细节

塑壳采用高精度注塑成型,尺寸公差控制在±0.1mm内,确保与排针精准对位(对位偏差≤0.05mm),减少插拔卡顿;端子经冲压+精密抛光处理,表面无毛刺,可避免划伤PCB或排针。

三、电气性能与可靠性

该排母的电气性能覆盖“信号稳定+小功率电源承载”双需求,可靠性符合工业级标准:

1. 信号传输稳定性

接触电阻≤20mΩ(典型值),在-40℃~+105℃温区内变化≤10mΩ,可兼容I2C、SPI、UART等数字信号传输,不会因接触电阻波动导致信号失真。

2. 电源承载能力

额定3A(AC/DC)可满足5V/12V小功率电源传输(如传感器供电、模块辅助电源),在25℃环境下连续工作时,端子温度≤60℃(低于PBT塑壳耐温上限),无过热风险。

3. 环境适应性

工作温区覆盖工业级高低温场景(如户外传感器、车载控制器),塑壳耐弱酸、弱碱腐蚀,端子镀锡层可抗氧化(存储1年以上接触电阻无明显变化),延长产品使用寿命。

四、应用场景与适配性

KH-2.54FH-1X16P-H8.5的兼容性强,可覆盖以下核心场景:

1. 工业控制领域

PLC模块接口、传感器节点(如温度/压力传感器)、小型电机驱动板(需信号+小功率电源);

2. 消费电子领域

智能家居设备(智能网关、智能门锁控制板)、小型家电(如加湿器、扫地机控制模块);

3. 通信设备领域

小型路由器、交换机的扩展接口模块;

4. 适配排针

可匹配同间距(2.54mm)的1×16P直插/弯针排针,无需额外适配成本,降低系统设计复杂度。

五、选型与安装注意事项

1. 选型要点

需确认3个核心参数:①排针数量(16P);②间距(2.54mm);③安装方式(直插);若需更高电流(如5A)或镀金端子(抗腐蚀),可联系金航标定制。

2. 安装注意

  • 焊接温度控制在260℃±5℃,单脚焊接时间≤3秒,避免塑壳受热变形;
  • 插拔排针时力度均匀(避免超过10N),防止端子弯曲;
  • 存储时远离潮湿(湿度≤85%RH)、高温(≤60℃)环境,避免塑壳老化。

综上,KH-2.54FH-1X16P-H8.5以“稳定接触+紧凑适配+工业级可靠性”为核心,是信号与小功率电源传输场景的高性价比选择。

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
