G5NB-1A-E DC24 产品概述

一、产品简介

G5NB-1A-E DC24 是欧姆龙(OMRON)推出的通用小型插针继电器(RELAY GEN PURPOSE SPST 5A),为单刀单掷常开(1A,Form A)触点设计,适用于各种控制与开关场合。封装为插件式,外形尺寸约 20.4 × 7 mm,便于在标准插座或 PCB 插针安装。

二、主要参数

  • 线圈电压:24 V DC
  • 线圈电阻:2.88 kΩ(线圈功率 200 mW,线圈电流 ≈ 8.33 mA)
  • 线圈类型:无极性单线圈(接线方向不限)
  • 触点形式:一组常开(SPST — 1A)
  • 触点容量(电阻负载):3 A @ 30 VDC;5 A @ 250 VAC
  • 最大切换电压:250 V AC;30 V DC
  • 最大切换电流:5 A
  • 触点材料:银合金(无镉)
  • 接触电阻:≤100 mΩ
  • 动作时间 / 释放时间:10 ms / 10 ms
  • 工作温度:-40 ℃ ~ +85 ℃
  • 引脚数:4(常见为 2 线圈 + 2 触点)

三、性能与特点

  • 小巧插件封装,便于批量装配与现场更换;20.4×7mm 适合紧凑电路布局。
  • 低功耗线圈(200 mW),适合电源受限或需并联大量继电器的场景。
  • 无极性线圈,安装时无需考虑极性,简化接线。
  • 触点采用无镉银合金,提高导通性与抗电弧能力,适合交流和直流负载(直流负载需注意电弧抑制)。
  • 快速响应(动作/释放 ~10 ms),适合常规控制信号速率的开关需求。

四、典型应用与接线建议

  • 应用场景:工业控制小型电源切换、仪表与传感器接口、家用/楼宇控制、继电保护的中间继电器等。
  • 接线提示:4 引脚通常为两端线圈、两端常开触点;通用插座或 PCB 针脚布局务必参考欧姆龙数据手册。
  • 抑制措施:驱动线圈建议并联二极管(DC 环境)或 RC/TVS 抑制(高频噪声);对感性负载(电机、电磁阀)建议在触点侧增加外部吸收回路或使用固态抑制器以降低触点磨损与焊接风险。
  • 负载考虑:直流开关易产生电弧,30 VDC/3 A 为电阻负载下额定,若为感性/电机负载应降额使用或选择专用功率继电器。

五、可靠性与选型注意

  • 使用前请参阅欧姆龙官方数据手册以获取电气寿命、机械寿命与耐振动/耐冲击等详细可靠性数据。
  • 若需频繁在较高电流或感性负载下切换,应考虑使用额定更高的继电器或加装开关保护电路。
  • 注意灯丝负载、浪涌电流与工作环境温度对触点寿命的影响,必要时进行降额设计。

六、订购与替代项

  • 型号:G5NB-1A-E DC24,品牌:OMRON(欧姆龙)。
  • 购买时确认封装(插件)、引脚配置与线圈电压(24V DC)一致;同类替代可考虑同厂不同封装或额定更高的 G5NB 系列型号,但以官方数据表为准。

如需我为您制作电路接线图、推荐插座脚位布局或给出常见抑制电路(二极管、RC、TVS、RC 抗干扰电路)示例,可告知使用场景与负载类型,我将给出更具体的建议。

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
