HF46F/024-HS1 产品概述
一、产品简介
HF46F/024-HS1 是宏发（HF）推出的一款超小型中功率继电器，额定线圈电压24V，单刀单掷常开（1A，SPST-NO）触点结构。该产品以体积小、功耗低和可靠性高为特点，适用于需要电隔离与小电流控制的电子设备和控制系统。
二、主要性能参数
- 线圈电压：24V DC
- 线圈功率：200 mW（低功耗设计）
- 线圈电阻：2.88 kΩ（与额定功率匹配）
- 触点形式：一组常开（单刀单掷-常开）
- 触点材料：AgNi（银镍合金）
- 触点容量（电阻负载）：5A @ 30VDC；5A @ 250VAC
- 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
- 引脚数：4（两脚线圈、两脚触点）
- 工作温度范围：-40℃ ～ +85℃
- 封装形式：插件，外形尺寸约20.5 × 7 mm
三、结构与封装说明
HF46F/024-HS1 采用插件式封装，便于通孔安装和维修。小巧的外形（20.5×7 mm）节省电路板空间，典型引脚排列适配常见插座和通孔焊接工艺。无极性单线圈设计，安装时无需考虑线圈极性，简化布线。
四、典型应用场景
适用于工控小型继电器模块、通信设备电源切换、楼宇自动化、安防控制、小型家电与仪器仪表等场合。尤其适合要求低功耗、频繁开关且切换电流不超过5A的中低功率应用。
五、选型建议
- 若系统为直流小电流负载（≤5A@30VDC），HF46F/024-HS1 可直接使用；交流负载需符合5A@250VAC 条件。
- 需注意最大切换电压限制（DC 30V），高压直流场合应选用额定更高的继电器。
- 对于高寿命或高冲击负载（如感性负载、电机起动），建议选用带抑制或更高容量的型号，并添加吸收电路以延长触点寿命。
六、安装与使用注意事项
- 插件焊接温度和时间应符合厂家推荐的通孔焊接规范，避免过热导致线圈或封装损伤。
- 线圈供电应为稳压24V，避免瞬态过压；额定功率200 mW，对电源干扰敏感时可加滤波或限流措施。
- 在切换感性负载时应并联吸收器（RC、TVS 或二极管）以抑制反向高压，保护触点和驱动电路。
- 工作环境应避免超出-40℃～+85℃，并注意潮湿、腐蚀性气体和强振动环境的防护。
七、可靠性与维护
触点采用AgNi材料，在一般电阻负载下具有良好耐久性和抗氧化性能。典型动作/释放时间均为10 ms，能满足多数控制时序要求。为保证寿命，建议在额定范围内运行并定期检查触点接触情况与焊点可靠性。
八、结论
HF46F/024-HS1 是一款面向中功率小体积应用的24V继电器，凭借低功耗（200 mW）、无极性单线圈设计和可靠的触点性能，适合嵌入式控制、电源切换与自动化系统中对空间和功耗敏感的场合。选型时请综合考虑负载类型、开关电压/电流及环境条件，以确保长期稳定运行。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
