HF46F-G/24-HS1T 产品概述

一、产品简介

HF46F-G/24-HS1T 是宏发(HF)推出的一款超小型24V直流继电器,属于插件封装的单刀单掷(SPST)常开型继电器。外形紧凑(20.5×7mm),线圈额定电压24V,线圈功率仅200mW,适合高密度安装与低功耗应用场景。

二、主要技术参数

  • 线圈电压:24V DC
  • 线圈功率:200mW;线圈电阻:2.88kΩ
  • 触点形式:一组常开(单刀单掷 - NO)
  • 引脚数:4(插件)
  • 触点容量(电阻负载):10A @ 250VAC;10A @ 30VDC
  • 最大切换电压:277V(AC);30V(DC)
  • 最大切换电流:10A
  • 触点材料:AgSnO2(银锡氧化物)
  • 接触电阻:≤100mΩ
  • 动作/释放时间:约10ms / 10ms
  • 工作温度范围:-40℃ ~ +85℃
  • 线圈类型:无极性单线圈(接线不分正负)
  • 封装形式:插件,尺寸20.5×7mm

三、性能特点

  • 超小体积:20.5×7mm 的紧凑封装,节省PCB空间,便于密集布局。
  • 低功耗线圈:200mW线圈功率,适合电源受限或需并联多个继电器的场合。
  • 大电流能力:触点额定10A,适用于中等功率交流与直流负载切换。
  • 良好触点可靠性:AgSnO2触点在开关性与抗焊接性上表现优异,适合有电弧或冲击负载的切换场景。
  • 宽温度范围:-40℃至+85℃,适应恶劣环境应用。

四、典型应用

  • 工业控制与自动化设备(PLC 输出、信号隔离)
  • 家电与HVAC 控制模块
  • 电源切换与保护电路(交流/直流负载切换)
  • 安防、门禁与通讯设备
  • 仪器仪表与测试测量设备

五、安装与使用建议

  • 因为线圈为无极性,直接接入24V DC 可正常工作;若使用二极管抑制线圈反向尖峰,请注意二极管会使线圈变成有极性,可能影响接线要求。建议采用RC吸收器或TVS以保持无极性并加速释放。
  • 布局时保证高压侧(最高277VAC)与低压侧足够爬电爬距和绝缘距离,满足安全规范。
  • 焊接时参考宏发的回流/波峰焊工艺建议,插件件应避免过长高温暴露以保护线圈与封装。
  • 对于感性负载建议并联抑弧器件或使用延时断开策略以延长触点寿命。

六、注意事项与选型建议

  • 若需频繁切换感性或高冲击负载,建议评估触点寿命并考虑使用外部抑弧措施或选择专用高寿命继电器型号。
  • 在直流高电流切换场合(接近30VDC/10A)应重视触点烧蚀风险,必要时进行冗余或采用固态继电器备选方案。
  • 选型时核对封装尺寸与孔位,确认插件插座或PCB孔位兼容。

HF46F-G/24-HS1T 以其微型化、低功耗和10A开关能力,适合各类中高可靠性控制场合,是追求体积与性能均衡设计的常用继电器选择。

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
