欧姆龙G5Q-1A4 DC24通用继电器产品概述

一、产品核心定位

欧姆龙G5Q-1A4 DC24是一款通用型单刀单掷(SPST-NO)常开继电器,专为中小功率电路的通断控制设计。该型号以24V直流无极性线圈为核心,搭配10A交流/5A直流的触点容量,兼具低功耗、宽温适应性与高可靠性,是家电、工业自动化、办公设备等领域的经典选型,符合RoHS环保标准,适配多样化场景需求。

二、关键参数与性能指标

G5Q-1A4 DC24的参数围绕线圈控制、触点切换、环境适应性三大核心维度设计,关键参数如下:

  1. 线圈参数
    采用24V直流无极性单线圈,线圈电阻2.88kΩ,额定功率仅200mW(驱动电流≈8.33mA),无需额外大功率驱动电路,可直接由单片机IO口(配合限流或三极管驱动)控制;动作时间10ms、释放时间5ms,响应速度满足快速通断需求。

  2. 触点参数
    触点形式为1组常开(SPST-NO),触点材料为银合金(无镉),接触电阻≤100mΩ(低接触压降);触点容量(电阻负载)为5A@30VDC、10A@250VAC,最大切换电流10A,最大切换电压277VAC/30VDC,可覆盖常见中小功率负载。

  3. 环境与机械参数
    工作温度范围**-40℃~+105℃,适应高低温极端环境;封装为插件式10×20mm**,4引脚设计,紧凑尺寸节省PCB空间,适合小型化设备布局。

三、核心特性与优势

  1. 低功耗驱动,适配微控制器
    200mW的线圈功率仅需约8mA驱动电流,无需复杂驱动电路,可直接对接51单片机、STM32等主流MCU的IO口(若IO口驱动能力不足,仅需外接1个NPN三极管即可实现可靠驱动),降低系统设计复杂度。

  2. 高触点容量,覆盖广负载
    10A交流/5A直流的电阻负载容量,可满足家电(空调、洗衣机)、工业控制(小型PLC扩展)、办公设备(打印机)等场景的小功率电机、电源切换需求;感性负载需降额使用(建议加续流二极管),进一步提升可靠性。

  3. 宽温可靠性,适应极端环境
    -40℃~+105℃的工作温度范围,超越普通继电器的温度阈值,可应用于车载(车载电子)、户外(安防设备)等高低温场景,长期稳定运行无故障。

  4. 环保无镉触点,符合全球标准
    银合金无镉触点设计,符合RoHS、REACH等全球环保法规,避免有害物质排放,适合出口产品与绿色设计需求;低接触电阻(≤100mΩ)减少触点压降与发热,延长触点寿命。

  5. 紧凑封装,节省空间
    10×20mm的插件封装体积小巧,4引脚布局简单,可在高密度PCB上灵活布局,适配小型化设备(如智能插座、小型控制器)的空间限制。

四、典型应用场景

  1. 家电控制领域
    用于空调、洗衣机、冰箱的电源通断控制,小功率电机(如洗衣机脱水电机)的驱动切换,以及温度传感器信号的通断控制。

  2. 工业自动化
    作为小型PLC的扩展IO模块,实现低压控制回路的通断;用于传感器信号切换、小型电磁阀驱动(降额使用),以及生产线设备的状态指示控制。

  3. 办公设备
    打印机、复印机的电源管理模块,负责主电源与待机电源的切换;小型电机(如走纸电机)的驱动控制,以及扫描组件的信号切换。

  4. 车载电子
    车载小功率负载(如车内氛围灯、小风扇、点烟器附件)的控制;适应车载-40℃~+85℃的温度范围,可靠性符合车载级要求。

  5. 安防设备
    门禁系统的电锁控制(如电磁锁的通断);报警装置的信号切换(如声光报警的触发控制),以及监控设备的电源管理。

五、选型与使用注意事项

  1. 线圈驱动验证
    确认输入电压为24V直流,无极性可正反接;若单片机IO口驱动能力不足(如STM32 IO口最大灌电流≈20mA,满足需求,但需注意压降),建议外接1个NPN三极管(如2N2222)实现驱动,避免IO口损坏。

  2. 触点负载限制
    严格遵循电阻负载5A@30VDC、10A@250VAC的限制;感性负载(如电机、继电器线圈)需降额50%使用,并在负载两端并联续流二极管(1N4007),防止触点电弧烧蚀。

  3. 焊接与安装
    插件焊接温度不超过260℃,焊接时间不超过10秒,避免高温损坏线圈绝缘;安装时需确保PCB引脚与继电器引脚对齐,避免虚焊。

  4. 环境防护
    避免在潮湿、腐蚀性气体(如硫化物)环境下使用,如需应用需加装防护外壳;禁止在爆炸危险环境中使用。

  5. 引脚定义确认
    4引脚通常为:线圈端(引脚1、2)、触点公共端(引脚3)、常开触点端(引脚4),需参考欧姆龙官方datasheet确认具体引脚顺序,避免接反导致功能失效。

综上,欧姆龙G5Q-1A4 DC24凭借低功耗、高可靠性与宽适应性,成为中小功率电路控制的优选继电器,可满足多行业的多样化需求。

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.
