SR4M4024 产品概述

一、产品简介

TE Connectivity(Potter & Brumfield / SCHRACK)SR4M4024 是一款通孔安装的安全继电器,标准型号属于 SR4 系列。该器件为四刀单投(4PST)结构,触点排列为 3 常开(3 Form A)与 1 常闭(1 Form B),旨在提供多回路隔离与可靠的开关控制能力,适用于需要多路分离与高可靠性的控制场合。

二、主要参数

  • 线圈电压:24 VDC(线圈电阻 720 Ω,线圈电流 33.3 mA,线圈功率 800 mW)
  • 必须吸合电压:18 VDC;必须释放电压:2.4 VDC
  • 额定接触电流:8 A(触点材料:银锡氧化物 AgSnO)
  • 最大开关电压:400 VAC
  • 安装类型:通孔,端接样式为 PCB 引脚(管件包装,器件状态:有源)
  • 工作温度范围:-25 °C ~ 70 °C
  • 基本产品编号:SR4M(本型号标注为 SR4M4024)

三、关键特性与优势

  • 多回路隔离:4PST 结构可同时控制四路电气回路,便于实现冗余或分配控制,尤其适合安全回路与主回路分离的设计。
  • 优质触点材料:AgSnO 触点抗电弧、抗焊接性好,适合频繁通断与较高电压下的可靠切换。
  • 适配 AC 主电源:最大开关电压 400 VAC,可直接用于常见 230 VAC 工频场合(注意根据负载类型做适当降额)。
  • 低线圈功耗:800 mW 线圈功耗有利于降低驱动电源负荷并简化驱动电路设计。
  • 良好动作裕量:18 V 吸合、2.4 V 释放,表明线圈对供电波动有足够的容错空间,易于与常见驱动器件配合使用。

四、典型应用场景

  • 工业控制与自动化设备中的多路隔离开关与安全切断;
  • 家用或商业电器需分路控制且要求可靠断开的大功率回路;
  • HVAC、泵浦与电机控制系统的保护与切换模块;
  • 测试设备与仪器中需要多路信号隔离的场合。

五、选型与使用建议

  • 对于感性负载(电机、线圈等)应考虑触点电流降额或使用外部抑制元件以延长触点寿命。
  • 驱动线圈时建议使用反向并联二极管或其它抑制电路,以保护驱动器件;注意不同抑制方案会影响释放时间与必须释放电压。
  • PCB 布局时为满足 400 VAC 的安全隔离需留意爬电距离与间隙,确保触点间以及触点对线圈间有足够绝缘距离。
  • 如果需要认证或更高耐久性,请在采购前核对具体型号的寿命、认证与环境试验数据。

六、包装与采购信息

  • 品牌:TE Connectivity(美国泰科)
  • 描述:RELAY SAFETY 4PST 8A(SR4M 系列)
  • 包装方式:管件(Tube),适合批量装配与通孔插件工艺。

如需详细机械尺寸、动静寿命、认证信息或电气寿命曲线,请参考 TE 官方数据手册或提供具体应用场景以便进一步确认选型。

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
