宏发HFD27/012-S DIP继电器产品概述
宏发（HF）HFD27/012-S是一款小型电磁继电器，采用DIP双列直插封装，尺寸紧凑（20.2×10.2mm），兼顾低功耗、高可靠性与快速响应，适用于对空间和性能有严格要求的电子设备，可满足工业控制、仪器仪表等多场景的切换需求。
一、产品基本定位与封装
HFD27/012-S属于宏发HFD27系列继电器，专为小型化、低功耗设计，采用DIP封装，无需额外适配复杂接口，可直接焊接于PCB板。20.2mm×10.2mm的紧凑尺寸，能轻松集成到万用表、小型PLC模块等空间受限的设备中，优化布局效率。
二、核心电气参数解析
1、线圈参数
- 额定电压：12V DC，适配常见低压直流电源；
- 线圈电阻：720Ω，驱动电流约16.7mA（12V÷720Ω），对驱动电路功率要求低；
- 额定功率：200mW，低功耗设计可减少线圈发热，避免长时间工作导致的性能衰减。
2、触点参数
- 触点材料：AgNi（银镍合金）+镀金，兼顾耐磨损性与抗氧化能力，降低接触电阻衰减风险；
- 负载容量（电阻负载）：1A@125V AC、2A@30V DC，覆盖常规低功率交直流负载；
- 切换极限：最大切换电压120V DC/240V AC，最大切换电流2A，适配中小功率场景；
- 接触电阻：≤50mΩ，低电阻可减少信号传输损耗，适合信号切换与小电流控制。
3、动作与释放特性
- 动作时间：≤7ms，响应速度快，可满足对切换及时性要求较高的场景（如传感器信号切换）；
- 释放时间：≤4ms，断开动作迅速，减少触点拉弧时间，延长电气寿命。
三、可靠性与环境适应性
1、宽温工作：工作温度范围-40℃~+85℃，覆盖工业级温度要求，可在低温（如北方户外设备）或高温（如设备内部散热环境）下稳定运行； 2、触点耐用性：AgNi+镀金结构抗电弧烧蚀能力强，可有效降低触点磨损，提升机械与电气寿命； 3、低发热设计：200mW额定功率使线圈发热极小，避免因过热导致的绝缘老化，适合长时间连续工作。
四、典型应用场景
HFD27/012-S的性能特点使其适用于以下场景： 1、工业控制：小型PLC模块、传感器信号切换、电机小功率启停控制； 2、仪器仪表：万用表、示波器、数据采集器的功能切换与信号路由； 3、智能家居：智能开关、安防设备的继电器控制（如门窗传感器联动）； 4、通讯设备：小型交换机、路由器的接口切换与状态控制； 5、汽车电子周边：车载小电器（如氛围灯、点烟器扩展）的低功率切换（需确认符合车载环境额外要求）。
总结：宏发HFD27/012-S是一款高性价比小型继电器，以紧凑封装、低功耗、可靠触点为核心优势，可满足多种工业与民用场景的切换需求，是小型电子设备集成的理想选择。

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.
