CJT A2541WV-9P 单排方针直插排针产品概述

CJT(长江连接器)推出的A2541WV-9P是一款专为2.54mm间距电路设计的单排方针直插排针,兼顾信号传输稳定性与小功率电流承载能力,广泛适配工业控制、消费电子、仪器仪表等多领域的连接需求,是电子设备内部连接的高性价比解决方案。

一、产品核心定位

A2541WV-9P属于通用型电子连接器件,核心定位为“稳定可靠、安装简便的单排方针直插排针”:

  • 区别于圆针的线接触方式,方针设计提升接触面积与信号完整性;
  • 直插安装简化PCB焊接流程,适合批量生产与后期维护;
  • 宽温范围与高性价比,适配中小电子设备的多样化需求。

二、关键参数与规格解析

该排针严格遵循2.54mm行业标准,核心参数如下:

参数类别 详细规格 关键说明 排针结构 1x9P(单排9位) 单排设计节省PCB布局空间 针间距 2.54mm(标准间距) 适配主流2.54mm插座接口 针型 方针(方形针脚) 平面接触,稳定性优于圆针 安装方式 直插式(插件焊接) 无需特殊工具,焊接操作简便 电气性能 额定电流3A/位、额定电压250V 满足小功率信号/电流传输需求 针脚长度 配合针6mm、端接针3mm 配合针适配对接插座,端接针适配PCB焊接 触头材质 黄铜(H62) 导电性能优、加工稳定性强 触头镀层 镀金(行业标准厚度) 耐腐蚀、低接触电阻(≤10mΩ) 环境适应性 工作温度-40℃~+105℃ 宽温范围适配极端场景 塑壳参数 塑高2.54mm、黑色(耐高温) 紧凑设计、阻燃性达UL94 V-0

三、结构设计细节优势

1. 方针接触设计

方形针脚与对接方针插座形成平面接触,相比圆针的线接触:

  • 接触面积提升约30%,有效降低接触电阻,减少信号传输损耗;
  • 插拔力更均匀(1~3N/位),反复插拔(≥500次)后仍保持稳定接触,避免虚接故障。

2. 直插焊接适配

  • 端接针3mm长度:适配常规1.6mm厚PCB板,既避免过短假焊,也防止过长刺穿PCB;
  • 配合针6mm长度:确保与对接插座的有效接触深度,减少虚接风险。

3. 紧凑塑壳结构

  • 塑高2.54mm与针间距一致,整体尺寸紧凑,节省PCB空间;
  • 黑色耐高温工程塑料:匹配-40℃~+105℃工作温度,兼具阻燃性,提升设备安全等级。

四、电气与环境性能特性

1. 稳定电气传输

  • 黄铜触头+镀金镀层:导电性能优异,镀金层耐腐蚀能力是镀锡的3倍以上,避免触头氧化;
  • 额定3A/位电流:满足小型电机、传感器供电等小功率需求;
  • 250V额定电压:符合低压电器安全标准,避免绝缘击穿。

2. 宽温环境适配

-40℃~+105℃的工作温度范围,可覆盖户外低温(北方冬季)、工业高温(电机控制柜)等场景,无需额外温控措施。

3. 机械可靠性

  • 注塑一体成型工艺:塑壳与针脚连接牢固,避免针脚松动;
  • 方针刚性结构:比圆针更强,插拔时不易弯曲变形,提升使用寿命。

五、典型应用场景

A2541WV-9P的通用特性使其适配多领域:

  • 工业控制:PLC模块I/O接口、传感器(温度/压力)连接、伺服电机控制板;
  • 消费电子:智能家居(智能开关、门锁控制板)、小型家电(加湿器、扫地机)内部连接;
  • 仪器仪表:万用表、示波器内部信号传输、数据采集卡接口;
  • 通信设备:小型路由器、交换机扩展接口板;
  • 汽车电子:车载小功率传感器(座椅传感器、温度传感器)连接(需配合汽车级认证场景)。

六、品牌与品质保障

CJT(长江连接器)是国内连接器行业资深厂商,拥有20余年生产经验:

  • 产品通过ISO9001质量体系认证、RoHS环保认证与REACH标准;
  • 供货网络覆盖全国,常规订单3~7天交货,性价比优于同类进口品牌;
  • 广泛应用于国内外电子企业,品质稳定可靠。

综上,CJT A2541WV-9P以“稳定接触、简便安装、宽温适配”为核心优势,是电子设备内部连接的优选方案。

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
