XL-IRM1838D红外遥控接收头产品概述

一、产品核心定位与应用场景

XL-IRM1838D是成兴光(Xinglight)推出的集成化红外遥控接收组件,专为低成本、小型化的红外遥控系统设计,无需外接红外光敏管、放大电路等辅助元件,直接输出数字信号,可快速对接单片机或控制器。

其典型应用场景覆盖:

  • 家用电子设备:电视、空调、机顶盒、风扇的红外遥控接收端;
  • 智能家居:智能灯、窗帘控制器、扫地机器人的遥控接收模块;
  • 便携/电池供电设备:小型红外遥控器接收器、移动电源控制端;
  • 工业辅助控制:小型电机、阀门的近距离红外遥控节点。

二、关键技术参数解析

XL-IRM1838D的核心参数兼顾兼容性与实用性,具体解析如下:

1. 工作电压与电流

  • 电压范围:2.7V~5.5V → 兼容3.3V(如STM32、ESP32)和5V(如51单片机)主流电源系统,无需额外电压转换电路;
  • 工作电流:400uA(低功耗) → 适合电池供电的便携设备,单节AA电池(1.5V升压后)可支持长期稳定工作。

2. 接收性能

  • 接收距离:15m → 满足室内常规场景(客厅、卧室)的遥控需求,户外近距离(≤10m)也能稳定接收;
  • 中心频率:37.9kHz → 与市场90%以上红外遥控器(如NEC、飞利浦协议)的载波频率匹配,兼容性强。

3. 环境适应性

  • 工作温度:-20℃~+85℃ → 覆盖北方冬季室内、南方夏季高温等场景,满足家电/工业设备的温度要求。

三、封装与引脚说明

XL-IRM1838D采用SIP-3(单列直插3脚)封装,尺寸为DIP-7MM(引脚间距符合常规DIP标准),安装简单,适合紧凑设计的产品(如超薄电视、小型遥控器)。

引脚定义(从左到右,正视接收头顶端):

  1. VCC:电源正极 → 接2.7~5.5V直流电源;
  2. GND:电源负极 → 接地;
  3. OUT:信号输出 → 输出解调后的TTL电平(低电平有效:接收有效信号时输出低,无信号时输出高)。

四、工作原理简述

该接收头为集成化单芯片设计,核心流程如下:

  1. 信号接收:内部红外光敏二极管捕获遥控发射的37.9kHz载波信号(红外光经数字编码调制后的信号);
  2. 滤波放大:内置滤波电路过滤可见光(阳光、灯光)杂波,放大电路将微弱信号提升至可检测电平;
  3. 解调输出:解调模块分离载波与数字编码(如NEC协议的地址码、数据码),输出TTL电平信号供控制器读取。

优势:集成度高,减少外部元件(无需外接电阻/电容),降低系统成本与体积。

五、环境适应性与可靠性

除基础参数外,XL-IRM1838D具备以下实用特性:

  • 抗干扰能力:内置红外滤波片,抑制可见光干扰,避免误触发;对非37.9kHz的红外信号隔离效果好;
  • 静电防护:符合ESD静电防护标准(±2kV接触放电),焊接/存储时无需额外防护即可避免损坏;
  • 温度稳定性:工作温度范围内中心频率偏移≤±1kHz,接收灵敏度无明显下降,可靠性高。

六、选型与应用注意事项

为确保稳定工作,需注意以下细节:

  1. 电源设计:VCC引脚建议并联0.1uF~1uF滤波电容,减少电源纹波影响;禁止超过5.5V电压输入;
  2. 安装角度:接收角度为±45°,安装时尽量朝向遥控发射方向,避免外壳遮挡(建议露出接收头顶端);
  3. 协议匹配:确认配套遥控器的编码协议(如NEC、RC5)与接收头兼容,若不匹配需调整编码;
  4. 静电防护:焊接时使用防静电烙铁,存储时放入防静电袋,避免人体静电损坏元件。

XL-IRM1838D凭借低功耗、高兼容性与紧凑封装,成为家电、智能家居等领域红外遥控系统的主流选型之一,可快速满足量产与定制化需求。

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
