XL-IRM1838B 红外遥控接收头产品概述

XL-IRM1838B是成兴光(Xinglight) 推出的一款小型化红外遥控接收头,采用SIP-3单列直插封装,专为各类电子设备的红外遥控信号接收设计,凭借低功耗、宽温适应、中距离接收等特点,成为家电、智能家居、小型电子装置等领域的常用元件。

一、产品定位与核心用途

这款接收头的核心作用是将红外遥控发射器发出的37.9kHz载波信号转换为电信号,输出给设备主控芯片解码,实现遥控指令的接收。其定位偏向通用型中距离红外接收,适配绝大多数民用及小型工业设备的遥控需求,无需额外复杂电路即可稳定工作。

二、关键技术参数详解

XL-IRM1838B的参数经过优化,兼顾性能与实用性,核心参数如下:

  • 工作电压:额定6V,属于低压供电范围,适配多数设备的电源系统(如5V/6V输出的单片机、电源模块);
  • 工作电流:仅500uA(微安级),低功耗特性突出,适合电池供电的便携式或无线设备;
  • 接收距离:15m(典型值),在普通家居环境(客厅、卧室)中无需近距离对准,可覆盖常见使用场景;
  • 中心频率:37.9kHz,是红外遥控领域的主流载波频率,与市面上90%以上的红外遥控器兼容;
  • 耗散功率(Pd):250mW,功率低、发热小,长时间工作无过热风险;
  • 工作温度:-40℃~85℃,宽温范围可适应北方低温、南方高温,甚至部分工业环境的温度波动。

三、封装与结构特点

采用SIP-3单列直插3引脚封装,引脚间距约6mm(DIP-6MM标注),结构紧凑:

  1. 安装便捷:直接焊接在PCB板上,无需复杂的插件工艺,适合批量生产;
  2. 体积小巧:封装尺寸约φ7mm×10mm(常见规格),不占用设备内部过多空间,适配小型家电(如迷你风扇、智能台灯);
  3. 内置集成电路:集成光敏二极管、放大电路、滤波电路,无需额外外接元件即可实现信号放大与干扰过滤,简化电路设计。

四、典型应用场景

XL-IRM1838B的通用性使其覆盖多个领域:

  1. 家用电子设备:电视、空调、机顶盒、DVD播放器等传统家电,15m接收距离满足客厅遥控需求;
  2. 智能家居产品:智能灯、智能窗帘、智能插座(电池供电款),低功耗特性延长设备续航;
  3. 小型电子装置:儿童玩具(遥控汽车、飞机)、小型安防探测器(红外遥控布防/撤防);
  4. 工业辅助设备:小型仪器仪表(如温湿度记录仪)的遥控参数设置,宽温范围适应车间环境。

五、性能优势总结

相比同类产品,XL-IRM1838B的核心优势体现在:

  1. 低功耗续航长:500uA工作电流,比同距离接收头低约30%,适合电池供电设备;
  2. 宽温稳定可靠:-40℃~85℃范围,可在极端环境下正常工作,无性能衰减;
  3. 兼容性强:37.9kHz主流频率,无需担心遥控器不匹配;
  4. 抗干扰性好:内置滤波电路,可有效过滤阳光、白炽灯等环境光干扰,减少误触发;
  5. 成本可控:成熟封装与工艺,性价比高,适合量产设备采用。

六、使用注意事项

为保证接收头稳定工作,需注意以下几点:

  1. 供电安全:避免超过额定6V电压(建议工作电压范围5V~6.5V),防止内部电路损坏;
  2. 安装位置:远离强光直射(如窗户旁、白炽灯下方),建议安装在设备正面偏上位置,减少遮挡;
  3. 引脚连接:需确认引脚顺序(通常引脚1=VCC,2=GND,3=OUT,具体以 datasheet 为准),避免接反烧毁;
  4. 静电防护:焊接时佩戴静电手环,防止静电击穿内部集成芯片;
  5. 干扰规避:远离强电磁干扰源(如电机、高频变压器),保证信号接收稳定性。

XL-IRM1838B凭借平衡的性能与成本,成为红外遥控接收领域的高性价比选择,广泛应用于各类需要无线遥控的电子设备中。

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
