HF46F/24-HS1T 功率继电器 产品概述

一、产品概述

HF46F/24-HS1T 是宏发(HF)推出的一款小型插件式功率继电器,额定线圈电压为24V DC,线圈功率仅200mW,体积紧凑(封装尺寸约20.5×7mm),适用于空间受限的电子设备与控制模块。该继电器兼顾低耗电线圈与较高的开关能力,是信号与小功率电源切换的理想选择。

二、主要特点

  • 低线圈功耗:200mW,适合电池供电或对功耗敏感的系统。
  • 紧凑封装:插件设计,便于板装与维修,外形尺寸约20.5×7mm。
  • 多种开关能力:最大切换电流5A,最大切换电压可达277V AC / 30V DC(依据负载和测试条件)。
  • 响应迅速:动作时间与释放时间均约10ms,适合较快的控制要求。
  • 可靠触点:接触电阻典型值约100mΩ,保证低电压降与良好导通性能。

三、关键电气参数

  • 线圈电压:24V DC
  • 线圈电阻:2.88 kΩ(由此线圈电流≈8.33 mA,线圈功率≈200 mW)
  • 触点容量(电阻性负载):3A@30VDC;5A@30VDC;5A@250VAC;3A@250VAC(不同测试条件下的额定值,请按具体应用场景选型)
  • 最大切换电压:277V AC;30V DC
  • 最大切换电流:5A
  • 接触电阻:≤100 mΩ
  • 动作/释放时间:约10 ms / 10 ms

四、典型应用场景

  • 工业控制:用于PLC外围、小型控制箱中的直流/交流回路切换。
  • 通讯设备:电源隔离、备用电源切换或信号路由。
  • 家电与安防:小功率电机、指示灯、电磁阀等控制。
  • 仪器仪表:低功耗测量系统中的电源或信号断接。

五、使用建议与注意事项

  • 线圈驱动:线圈电流约8.3mA,MCU输出引脚可直接驱动,但建议加外部驱动器(晶体管或MOSFET)以提高抗干扰性并保护MCU。并在线圈两端并联反向二极管以抑制反向脉冲。
  • 触点保护:对感性负载(电机、继电器线圈等)应并联抑制器件(RC、TVS、二极管或工频电抗器)以延长触点寿命。
  • 负载类型区分:直流开关时触点弧光更难熄灭,应按直流额定值并作适当的额定降额;对于高频或大电流开关应考虑继电器触点寿命衰减。
  • 环境与散热:避免长期超温工作,存放与工作环境应参考厂家温度与湿度规范。
  • 寿命与可靠性:电气寿命与机械寿命受负载类型、工作频率与抑制措施影响,设计前请参照厂家完整技术资料或样品测试数据。

六、封装与安装

  • 封装方式:插件(插脚式)便于手工或波峰/选择性焊接装配。
  • 外形尺寸:约20.5 × 7 mm(具体尺寸与引脚排列请参照产品图纸)。
  • 安装建议:保持继电器周边足够间距以利散热并避免高压爬电路径短路。

七、选型与采购提示

在选型时确认触点组合、负载类型(直流/交流、感性/电阻性)、工作频率及预期寿命。若用于严苛环境或关键控制环节,建议向供应商索取完整数据表与寿命测试报告,并做必要的软硬件保护设计。

如需进一步的电气图、引脚定义或使用案例,可提供具体应用场景,我可协助给出接线示意与保护电路建议。

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
