HF3F-L/5-1HL1T 磁保持继电器产品概述

一、产品简介

HF3F-L/5-1HL1T 是宏发(HF)推出的一款小型磁保持(latching)继电器,采用插件(DIP)封装,外形尺寸约 15.2 × 19 mm,四引脚布局,适合印制板插装或插件式安装。该型号为单线圈单刀单掷(1组常开)触点结构,适用于需要记忆保持状态、低能耗驱动的开关与信号切换场合。

二、主要电气参数

  • 线圈电压:5 V(单线圈);线圈电阻 62.5 Ω,线圈电流约 80 mA;额定线圈功率 400 mW。
  • 触点形式:单刀单掷(1 组常开)。
  • 触点材料:AgSnO2(抗电弧、耐焊点扩展)。
  • 触点容量(电阻性负载):10 A @ 277 VAC(额定);最大切换电压 30 V @ DC、277 V @ AC;最大切换电流可达 15 A。
  • 接触电阻:典型 100 mΩ。
  • 动作/释放时间:动作 ≈ 8 ms,释放 ≈ 5 ms。
  • 工作温度范围:-40 ℃ 至 +85 ℃。

三、结构特点与材料优势

  • 磁保持结构:继电器在通电脉冲后保持接点状态,断电后仍维持该状态,适合低功耗或需断电记忆的系统。
  • 单线圈设计:通过极性或短脉冲控制实现置位/复位,简化线圈布线、减少占用资源。
  • AgSnO2 触点:相对于纯银触点,AgSnO2 在切换有火花或高电压时更耐弧蚀、寿命更长,适合交流或含感性负载的应用场景。
  • 紧凑封装:DIP 插件形式便于装配与更换,适合批量生产的电路板设计。

四、典型应用场景

  • 楼宇与工业控制:用于状态记忆的开关控制、远程换位。
  • 电力与配电设备:可用于交流负载切换、备用线路保持等(注意按额定值选型)。
  • 仪表与计量装置:低功耗记忆、断电保持设定。
  • 家电与安防设备:模式保存、状态切换模块。
  • 电子继电器模块与接口板:作为可控、保持型输出单元。

五、选型与使用建议

  • 驱动方式:线圈额定电压 5 V、电阻 62.5 Ω,工作电流约 80 mA,设计驱动电路时应考虑脉冲驱动与极性控制(单线圈磁保持继电器通常需反向脉冲或专用驱动方式实现复位)。
  • 负载匹配:尽量在额定触点容量内工作,若需切换感性或突入电流较大的负载(电机、继电器线圈、变压器等),应加入限流、软启动或电弧抑制电路(RC 吸收、电阻或避雷器等)。
  • PCB 与安装:预留插件空间,注意散热与绝缘间隙;长期在高温环境下使用应参照温度特性曲线选择合适的工作点。
  • 寿命与维护:触点寿命受切换电流、电压及负载性质影响,频繁切换或大电流环境下建议留有余量并定期检查接触情况。

六、注意事项

  • 本型号为磁保持继电器,非通电保持型,使用时请确认控制逻辑与驱动方案;
  • 切换高电压或感性负载时须采取抑制措施以保护触点并延长寿命;
  • 实际应用前建议参考宏发提供的详细数据手册与机械图纸,进行样品验证与环境测试。

以上为 HF3F-L/5-1HL1T 的主要特性与应用建议,可作为选型与电路设计的参考依据。

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
