HF32FV-G/24-HSTF 产品概述

一、产品简介

HF32FV-G/24-HSTF 是宏发(HF)推出的一款超小型中功率继电器,采用插件封装,外形尺寸仅 18.4 × 10.2 mm。该继电器为 24V 无极性单线圈设计,触点为一组常开(单刀单掷-NO),适用于空间受限但需可靠开关控制的场合。结构紧凑、响应快速、触点材料为 AgSnO2,兼顾导通性能与抗电弧能力。

二、主要特点

  • 小体积、高密度:18.4 × 10.2 mm 插件封装,便于在高密度电路板上布置。
  • 中功率能力:触点额定容量 10A@250VAC,最大切换电流 10A,满足一般电源与交流负载的开关需求。
  • 低线圈功耗:线圈功率 450 mW,对驱动功率要求低,线圈电阻 1.28 kΩ,对应驱动电流约 18.8 mA。
  • 无极性线圈:线圈为无极性设计,接线时不区分正负极,安装更方便。
  • 快速响应:动作时间约 8 ms,释放时间约 5 ms,适合常规控制场合。
  • 宽温工作:工作温度范围 -40℃ ~ +105℃,适应性强。

三、技术参数(要点)

  • 型号:HF32FV-G/24-HSTF
  • 线圈电压:24 V DC
  • 线圈功率:450 mW(线圈电阻 1.28 kΩ,线圈电流 ≈ 18.8 mA)
  • 触点形式:一组常开(SPST-NO)- 单刀单掷
  • 引脚数:4(插件式)
  • 触点材料:AgSnO2
  • 触点容量(电阻负载):10 A @ 250 VAC
  • 最大切换电压:250 V AC
  • 最大切换电流:10 A
  • 接触电阻:≤ 100 mΩ
  • 动作/释放时间:约 8 ms / 5 ms
  • 工作温度:-40℃ ~ +105℃
  • 封装尺寸:18.4 × 10.2 mm(插件)

四、典型应用

  • 工业控制板、PLC 外围开关模块
  • 通信、电源分配与监控设备
  • 楼宇自控、安防系统、门禁控制单元
  • 仪器仪表、小型家用电器控制电路
  • 汽车电子的非关键回路(需按应用评估环境与寿命)

五、安装与接线建议

  • 推荐采用与插件座配套的 PCB 孔位及固定方式,保证机械牢固性。
  • 线圈为无极性,接线更简便;但驱动端仍建议在驱动晶体管并联续流二极管或 TVS,以吸收反向脉冲,保护驱动器件。
  • 对于感性负载(电机、继电器线圈、感性阀等),应加 RC 抑制器或瞬态抑制器,避免触点电弧加速磨损。
  • 负载为灯泡或电机等有高浪涌电流的场合,应核算峰值电流,必要时选用具有更高耐冲击能力的继电器或并联软启动元件。
  • 预留足够的散热与空气间隙,避免在高温高湿环境下长期超额载流。

六、选型与使用注意事项

  • 虽然额定为 10A@250VAC,但该数值通常针对阻性负载;交流感性或容性负载需按厂方数据表进行额外考虑与降额使用。
  • 触点材料为 AgSnO2,耐电弧性能较好,但频繁大电流开关会缩短使用寿命,应在设计时评估开关次数与负载类型。
  • 若对电寿命、机械寿命或冲击/振动有严格要求,请索取完整数据表与可靠性测试报告进行验证。

总结:HF32FV-G/24-HSTF 以其超小体积、低线圈功耗和 10A 的中功率开关能力,适合空间有限且需可靠开关控制的工业与民用电子产品。选型时应结合负载特性与使用频率,采取必要的抑制与保护措施以延长使用寿命。若需完整参数或封装图纸,可联系供应商获取详细数据表。

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
