HF115F/024-2ZS4 产品概述

一、产品简介

HF115F/024-2ZS4 是宏发(HF)推出的一款小型双刀双掷(2C/DPDT)封装继电器,采用标准 DIP 结构,尺寸约 29 × 12.7 mm,适合 PCB 插装应用。该继电器为无极性单线圈设计、线圈额定电压 24V,线圈功耗低(400 mW),在工业控制、家电、电源切换和信号隔离等领域具有良好通用性。

二、主要技术参数

  • 触点形式:两组转换(2C / 双刀双掷)
  • 线圈电压:24 V(无极性单线圈)
  • 线圈功耗:400 mW(线圈电阻 1.44 kΩ,静态电流 ≈ 16.7 mA)
  • 触点材料:AgCdO(抗电弧、耐磨损)
  • 触点电阻:≤100 mΩ(典型)
  • 最大切换电流:8 A(阻性负载)
  • 触点容量(阻性负载):8 A @ 250 VAC
  • 最大切换电压:440 V AC / 300 V DC
  • 动作时间:约 15 ms;释放时间:约 8 ms
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 引脚数:8(DIP 封装)

三、性能特点

  • 低功耗线圈:400 mW 的线圈功耗便于微控制器驱动,并减少发热与功耗负担。
  • 无极性线圈:接线不区分极性,简化电路设计与布线检查(但外部仍建议配合合适的抑制元件)。
  • 强耐压与大电流能力:支持高至 440VAC/300VDC 的切换电压,以及 8A 的阻性负载开关,适合交流电源和直流电源的通用开关需求。
  • 工业级工作温度:-40~+85 ℃,适用于较恶劣的环境条件。
  • 可靠触点材料:AgCdO 在交流负载开关上具有良好抗电弧性能,适合频繁开关场合(需注意环保合规性)。

四、典型应用场景

  • 工业控制继电与信号切换(PLC 外围扩展、控制板)
  • 家用电器与HVAC(电源切换、模式切换)
  • 电源管理与UPS 测试回路切换
  • 仪器仪表的隔离与线路选择
  • 低功耗控制系统中的中小功率负载控制

五、选型及使用建议

  • 驱动能力:线圈电流约 16.7 mA(24V/1.44kΩ),驱动器(MCU、MOS)需能提供稳定电流并考虑线圈吸收回路。
  • 保护措施:对直流线圈建议并联二极管(开关瞬变吸收),对交流负载建议使用 RC 吸收、电阻/电容串联或 MOV,以抑制触点电弧与抖动。
  • 负载类型:对感性负载(电机、电磁线圈等)应按感性电流/峰值电压进行降额或采用保护电路,避免快速损耗触点。
  • PCB 布局:高压侧保持足够爬电距离和绝缘,触点走线尽量短且宽,接地与信号线分离。

六、注意事项与可靠性建议

  • 环保合规:AgCdO 含镉成分,选型时请确认是否满足目标市场的 RoHS/环保要求。
  • 机械与电寿命:具体的开关寿命(电寿命、机械寿命)应以官方数据表为准,设计时留有安全裕量。
  • 温度影响:在高温环境中线圈功耗与触点性能会受影响,必要时进行温升测试。
  • 维护与替换:对于频繁开关或感性大电流应用,建议定期检查触点磨损与接触电阻变化,作为预防性维护依据。

总结:HF115F/024-2ZS4 是一款结构紧凑、线圈功耗低且适用电压电流范围广的通用型 DPDT 小型继电器,适合多种控制与切换场景。在实际应用中,请结合负载类型、保护措施与环境条件进行合理选型与防护设计。若需完整电气寿命与更多机械参数,请参考宏发官方数据手册。

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
