BW433SNX21-5W2弹簧天线产品概述

一、产品核心定位与设计特点

BW433SNX21-5W2是BAT WIRELESS(蝙蝠无线) 针对433MHz ISM频段推出的小型化弹簧天线,专为空间受限的射频终端设计。其核心设计亮点在于螺旋弹簧结构:相比传统鞭状天线,体积大幅缩小的同时,保留了可靠的射频辐射性能,可适配传感器节点、遥控器等紧凑设备的集成需求。

型号命名逻辑清晰:

  • “BW”:品牌标识;
  • “433”:中心频率(433MHz ISM频段);
  • “SNX”:弹簧天线系列代号;
  • “21/5”:天线长度(21mm)与直径(5mm);
  • “W2”:增益参数(2dBi)。

二、关键性能参数解析

该天线的性能参数精准匹配433MHz频段的工业/物联网应用需求,核心指标如下:

1. 频段与兼容性

工作于433MHz ISM免授权频段,无需额外频谱申请,可直接部署于工业控制、物联网等场景;中心频率精度符合射频系统匹配要求,与主流无线模块(如CC1101、SX1278、A7105等)直接兼容。

2. 增益与覆盖

增益达2dBi,相比普通弹簧天线(通常1dBi左右)提升约30%的有效辐射功率,可扩展信号覆盖范围(中短距离场景:室内100-300米,室外300-500米),减少终端与基站间的信号衰减。

3. 阻抗与驻波比

阻抗匹配为50Ω(射频系统标准阻抗),无需额外阻抗匹配电路;驻波比(VSWR)≤1.8,远低于“VSWR≤2”的通用要求,信号反射损耗<1dB,传输效率显著提升,可降低系统功耗与信号误码率。

4. 耐功率与可靠性

最大承受功率50W,高于同类弹簧天线(常规10-30W),可适配大功率发射模块,避免天线因过功率损坏,延长产品使用寿命。

三、结构特性与环境适应性

1. 超小型化设计

直径仅5mm、长度21mm,属于“指尖级”天线,可轻松集成于传感器节点、遥控器、小型射频终端等空间受限设备中,无需额外占用安装空间。

2. 宽温工作范围

工作温度覆盖**-40℃~+80℃**,满足极端环境需求:

  • 低温场景:北方户外、冷链监测;
  • 高温场景:工业车间、车载终端;
    无需额外散热/保温措施,可靠性稳定。

3. 灵活安装方式

采用裸露弹簧结构(无特殊封装),可通过焊接、螺纹固定或卡扣式安装适配不同终端,安装流程简单,降低终端集成成本。

四、典型应用场景

结合小尺寸、宽温适应性与433MHz频段特性,该天线广泛应用于以下场景:

  1. 工业物联网(IIoT):设备状态监测终端(电机、泵体振动监测)、远程控制节点(阀门、开关控制);
  2. 无线遥控器:工业遥控器(起重机、叉车控制)、智能家居遥控器(窗帘、灯光控制);
  3. 智能传感器网络:环境监测传感器(温湿度、土壤湿度)、农业物联网终端(大棚灌溉控制);
  4. 公共事业终端:无线抄表系统(水表、电表)、门禁读卡器(小区/办公楼门禁);
  5. 车载与户外应用:车载胎压监测(TPMS)、户外追踪设备(物流标签、宠物追踪)。

五、品牌与可靠性保障

BAT WIRELESS是国内专注射频天线研发的专业厂商,拥有10+年天线设计经验,产品覆盖ISM、蓝牙、WiFi等多频段。BW433SNX21-5W2经过严格可靠性测试:

  • 振动测试(符合GB/T 2423.10标准);
  • 温度循环测试(-40℃~+80℃循环100次);
  • 盐雾测试(5% NaCl溶液,48小时);

确保在复杂环境下长期稳定运行,同时提供定制化服务(如频率微调、增益调整),满足客户个性化需求。

该产品以“小体积、高性能、宽适应”为核心优势,是433MHz频段无线终端的高性价比天线选型。

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
