对射式光电开关XL-ITR20005产品概述

XL-ITR20005是成兴光(Xinglight)推出的一款对射式光电开关,采用光电三极管作为输出单元,主打小体积、低功耗、快速响应的特点,适用于各类小型设备的非接触式位置/物体检测场景。

一、产品基本定位与应用场景

该产品属于低成本、高可靠性的基础型光电检测器件,核心用于需要精准判断“物体遮挡/存在”的场景,典型应用覆盖:

  • 办公设备:打印机/复印机的纸张进纸检测、硒鼓安装状态检测;
  • 小型家电:微波炉门盖闭合检测、洗碗机餐具位置检测;
  • 自动售货机:商品落位确认、出货通道堵塞检测;
  • 玩具/智能家居:玩具车避障感应、门窗状态监测(如智能门锁辅助检测)。

二、核心参数详解

XL-ITR20005的参数围绕“红外发射+光电接收”的核心功能设计,关键参数如下:

2.1 光电特性参数

  • 波长:940nm(红外光):避开可见光干扰,环境适应性更强;
  • 正向压降(Vf):1.2V:发射端LED功耗低,适合低电压供电场景;
  • 正向电流(If):50mA:最大正向工作电流,需控制在额定范围内避免损坏;
  • 输出类型:光电三极管:相比普通光电二极管,具有电流放大作用,检测灵敏度更高。

2.2 电气特性参数

  • 集射极击穿电压(Vceo):35V:接收端三极管的集射极耐压值,保障高压下的可靠性;
  • 集电极电流(Ic):20mA:接收端最大输出电流,满足一般电路驱动需求;
  • 直流反向耐压(Vr):5V:接收端反向电压限制,需注意电路极性;
  • 响应速度:上升/下降时间15us(@1mA,1kΩ负载):在1mA工作电流、1kΩ负载条件下,响应速度快,适合高速检测场景。

2.3 环境与可靠性参数

  • 工作温度:-20℃~+85℃:温宽适中,可适应大部分室内/户外(非极端环境)应用;
  • 封装形式:DIP:双列直插封装,便于插件焊接,适合批量生产组装。

三、产品性能特点

结合参数与实际应用,XL-ITR20005具有以下核心优势:

  1. 抗干扰能力强:940nm红外波长不受可见光影响,减少误触发;
  2. 检测灵敏度高:光电三极管输出自带放大,无需额外信号放大电路;
  3. 响应速度快:15us的上升/下降时间,满足小型设备的快速检测需求;
  4. 低功耗设计:1.2V正向压降+小电流工作,适合电池供电的便携设备;
  5. 可靠性稳定:-20~+85℃温宽+35V耐压,适应不同工况下的长期使用。

四、工作原理与结构

4.1 工作原理

XL-ITR20005为对射式结构,由两部分组成:

  • 发射端:内置红外LED,通电后发射940nm红外光;
  • 接收端:内置光电三极管,当发射端的红外光直接照射到接收端时,三极管导通(输出电流变化);若中间有物体遮挡红外光,接收端无光照,三极管截止(输出电流显著降低)。

通过检测接收端的电流/电压变化,即可判断“物体是否存在/遮挡”。

4.2 结构特点

采用DIP封装,发射端与接收端为分离式设计(需根据应用场景安装对齐),体积小巧,适合紧凑空间内的布局。

五、应用注意事项

为保障产品性能与寿命,使用时需注意:

  1. 电流限制:发射端正向电流(If)不得超过50mA,接收端集电极电流(Ic)不得超过20mA;
  2. 电压限制:接收端反向电压(Vr)不超过5V,集射极电压(Vceo)不超过35V;
  3. 环境要求:避免强光直射接收端(如阳光、强LED灯),防止误触发;
  4. 安装对齐:发射端与接收端需保持直线对齐,距离根据检测需求调整(一般小型设备内距离不超过10cm);
  5. 温度范围:工作温度需控制在-20℃~+85℃内,超出范围可能导致性能下降或损坏。

六、典型应用示例

以打印机纸张进纸检测为例:

  • 发射端安装在进纸通道一侧,接收端安装在另一侧;
  • 无纸张时,红外光直接照射接收端,三极管导通,电路输出高电平;
  • 纸张进入通道遮挡红外光时,接收端截止,输出低电平;
  • 打印机主控芯片根据电平变化,判断纸张是否到位,控制进纸电机启停。

该应用充分发挥了XL-ITR20005的快速响应与高可靠性,满足打印机“逐张进纸检测”的需求。

总结:XL-ITR20005作为一款基础型对射式光电开关,以高性价比、稳定可靠的特点,成为小型设备非接触检测的优选器件,覆盖办公、家电、智能硬件等多领域应用。

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.
