EVPAWED40 产品概述

一、产品简介

EVPAWED40 是松下(PANASONIC)推出的一款超薄表面贴装微动开关,外形尺寸仅 3.0 mm × 2.0 mm,整体高度 0.6 mm,适用于对厚度、空间有严格限制的便携式电子产品。该开关为单刀单掷(SPST)结构,圆形按钮外观,黑色按帽,具有 IP67 防护等级,能够满足常见的防尘、防水要求,适配移动电话、便携式音响等操作按键场景。

二、主要规格参数

  • 型号:EVPAWED40(PANASONIC)
  • 电路结构:单刀单掷(SPST)
  • 外形尺寸:3.0 mm × 2.0 mm
  • 高度:0.6 mm
  • 安装方式:立贴(SMD)
  • 引脚样式:SMD 接片
  • 按钮形状:圆形按键/盖帽(黑色)
  • 作用力:3.3 N
  • 触点电流:20 mA
  • 额定电压:15 V
  • 防护等级:IP67
  • 带支架:不带支架
  • 工作寿命:300,000 次
  • 工作温度:-40 ℃ ~ +85 ℃
  • 特性:带传动点,确保良好操作手感

三、结构与设计特点

  • 超薄低剖面设计(0.6 mm),便于超薄机身与窄间距布局。
  • 带传动点设计,增强触感反馈,按键操作更明确,利于人机交互体验。
  • IP67 等级密封结构,能在潮湿及多尘环境下长期工作(实际防护效果依赖于整机设计与装配工艺)。
  • SMD 引脚便于自动化回流焊接与高速贴装,提高生产效率。

四、性能与可靠性

  • 额定电压与电流(15 V / 20 mA)适合用作信号/低功耗开关输入,需避免超过触点额定值以防触点损坏或接触不良。
  • 工作寿命 30 万次,适合需要频繁操作但要求可靠性的便携终端产品。
  • 宽温度范围(-40 ℃ ~ +85 ℃),适配户外或温度变化较大的使用环境。

五、典型应用场景

  • 移动电话、智能终端的侧键/功能键
  • 便携式音乐播放器、蓝牙音箱等消费电子设备的控制按键
  • 手持仪器、便携式测量设备的操作开关
  • 其它要求超薄、高防护等级的小型开关场合

六、PCB 安装与焊接建议

  • 建议根据松下官方尺寸图或 PCB 布局建议设计焊盘,确保焊接强度与密封可靠性;开关为 SMD 结构,适用回流焊流程。
  • 对于 IP67 密封性能,整机侧应配合合适的密封结构或涂层工艺,单个开关的防水能力不能代替整体外壳密封设计。
  • 建议遵循厂商的回流温度曲线与预热、保温参数,避免超过器件允许的温度应力;如需洗板,建议确认清洗剂与密封材料的兼容性或采用不需清洗的工艺。

七、选型与采购信息

  • 品牌:PANASONIC(松下)
  • 封装:SMD,3×2 mm 贴片
  • 按帽颜色:黑色
  • 选购时注意核对额定电气参数(15 V / 20 mA)、寿命与防护等级(IP67)以满足产品设计要求。建议向松下或授权分销商索取完整数据手册与样品进行验证。

八、注意事项与实用建议

  • 该开关适合做信号类按键,不建议用于高电流或高电压负载。
  • 在整机防水设计中,优先考虑整体外壳密封和按键周边的密封措施,确保长期 IP67 性能。
  • 在电路设计上为 MCU 或输入端增加防抖处理(硬件 RC 或软件滤波)以保证按键可靠识别。
  • 若需更高的机械固定强度或特殊按键造型,可考虑在 PCB 上增加支撑结构或选用带支架型号。

以上为 EVPAWED40 的概述与应用建议,更多详细机械尺寸、焊接工艺与环境测试数据建议参照松下官方数据手册或联系供应商获取技术支持。

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
