DF40C-24DS-0.4V(51) 板对板连接器产品概述

一、核心参数总览

DF40C-24DS-0.4V(51)是HRS(广濑电机)推出的双列立贴板对板连接器,核心参数精准适配小型化电子设备需求:

  • 引脚总数:24Pin(双列各12Pin)
  • 引脚间距:0.4mm(高密度小间距设计)
  • 安装方式:表面贴装(SMD)立贴
  • 连接方式:槽型对接(精准定位)
  • 额定电流:300mA/引脚(AC/DC通用)
  • 触头镀层:镀金(Au)(耐腐、低阻)
  • 工作温度范围:-35℃至+85℃(宽温适应)
  • 品牌与型号:HRS广濑 DF40C-24DS-0.4V(51)

二、关键设计特点

1. 高密度小间距布局

0.4mm引脚间距搭配24Pin双列结构,在12mm×3mm左右的PCB占用面积内实现多通道传输,完美解决便携式设备“空间紧张”的设计痛点,适合可穿戴、小型物联网终端等场景。

2. 立贴安装节省空间

采用SMD立贴结构,相比卧贴/插针式设计:

  • 平面占用面积减少30%以上;
  • 兼容标准回流焊工艺,无需手工焊接,提升产线效率;
  • 垂直高度控制在2.5mm以内(参考官方图纸),避免与周边元器件干涉。

3. 槽型对接提升可靠性

槽型对接结构通过机械定位槽+防呆设计,实现:

  • 对接时引脚零错位,减少接触不良风险;
  • 对接后机械稳定性提升40%(对比普通直插结构),耐受轻微振动(如汽车电子、工业设备)。

4. 镀金触头保障传输质量

触头表面镀金厚度≥0.2μm(HRS标准),具备:

  • 耐腐蚀性:可长期抵御潮湿、盐雾环境;
  • 低接触电阻:≤50mΩ(典型值),减少信号传输损耗;
  • 抗氧化:避免长期使用后接触电阻骤增导致的信号中断。

三、典型应用场景

DF40C-24DS-0.4V(51)的参数特性使其适配多类场景:

1. 便携式电子设备

智能手环、蓝牙耳机、便携式血糖仪等设备内部,需连接主板与传感器、电池、显示模块,该连接器的小间距+立贴设计完美适配紧凑空间。

2. 智能家居模块

温湿度传感器、门窗传感器与控制板的板对板连接,宽温范围(-35~85℃)可适应家庭环境的温度波动,稳定传输信号。

3. 工业小型控制器

PLC扩展模块、工业传感器接口板等设备,需耐受轻微振动与温度变化,槽型对接+宽温特性满足工业级可靠性需求。

4. 物联网终端

小型物联网网关、智能门锁等终端,需传输WiFi、蓝牙、传感器数据等多信号,24Pin引脚数可实现“信号+电源”并行传输。

四、可靠性与性能优势

1. 宽温工作稳定性

覆盖-35℃至+85℃,可在低温户外(如北方冬季)、高温室内(如设备长时间运行) 环境下稳定工作,无性能衰减。

2. 长插拔寿命

槽型结构+镀金触头配合,插拔寿命≥500次(符合HRS工业级标准),适合需要频繁维护/更换模块的场景(如医疗设备)。

3. 中小功率承载能力

300mA/引脚的额定电流可满足:

  • 低功耗设备电源传输(如可穿戴电池供电);
  • 多通道信号并行传输(如数字信号、模拟信号)。

五、安装与兼容性要点

1. 安装工艺要求

  • 需采用标准回流焊工艺(温度曲线参考HRS官方建议);
  • 焊盘设计需严格遵循DF40C系列封装图纸(引脚间距0.4mm、焊盘尺寸精准),避免错位导致焊接不良。

2. 对接兼容性

需匹配同系列HRS母座(如DF40C-24DP-0.4V),不同品牌/系列产品可能存在尺寸偏差,导致对接失败或接触不良。

3. 防呆设计注意

连接器自带极性防呆结构,安装时需对齐母座的防呆标识,避免反向对接损坏触头。

该产品凭借高密度、高可靠性与宽温适配性,成为小型电子设备内部板对板连接的优选方案,广泛应用于消费电子、工业控制、物联网等领域。

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
