XL-ITR8402 对射式光电开关产品概述

一、产品定位与核心属性

XL-ITR8402是国产厂商成兴光(Xinglight)推出的低成本对射式红外光电开关,核心采用「红外发射管+光电三极管」的组合结构,主打常规场景下的物体有无检测,是机械开关的实用替代方案。该产品无需复杂调试,安装灵活,适配多数低压直流系统。

二、关键参数与实际意义

产品参数直接决定应用适配性,以下是核心参数的解析:

  • 正向压降(Vf):1.2V:发射端红外二极管导通时的正向电压,仅需3.3V/5V低压即可驱动,无需额外升压电路,适合电池供电场景。
  • 集射极击穿电压(Vceo):30V:接收端光电三极管的集电极-发射极最大耐压,可兼容12V以下低压系统,避免过压损坏。
  • 集电极电流(Ic):10mA:接收端最大允许工作电流,具备一定驱动能力,无需放大电路即可直接输出信号至MCU或小型负载。
  • 直流反向耐压(Vr):5V:发射端二极管的反向最大耐压,使用时需避免反向电压超标(如误接电源极性),防止器件击穿。
  • 波长:940nm:发射光为红外不可见光,避开可见光干扰(400-760nm波段),环境光影响小,室内场景表现稳定。
  • 开关响应时间:15us(@1mA、1kΩ):上升/下降时间均为15微秒,可满足常规物体通过的快速检测(如每秒数十次的计数需求)。

三、核心性能优势

  1. 对射式检测可靠性:通过「发射-接收光路阻断」原理检测物体,不受物体颜色(除镜面强反光)、材质影响,稳定性优于反射式光电开关。
  2. 光电三极管的信号放大:相比光电二极管,自带电流放大作用,输出信号强度更高,降低后续电路的信号处理难度。
  3. 低功耗易驱动:发射端仅需5-10mA电流即可工作,接收端电流也在毫安级,适合低功耗系统。
  4. 抗干扰能力强:940nm红外波长与可见光无重叠,明亮环境下仍能保持稳定检测。

四、典型应用场景

该产品因成本低、安装灵活,广泛用于:

  1. 小型设备内部检测:打印机/复印机的纸张有无检测、传真机进纸传感器。
  2. 家电控制辅助:消毒柜、烤箱的门/盖关闭检测,洗衣机水位辅助检测(配合其他传感器)。
  3. 小型自动化辅助:小型流水线工件有无检测、传送带物体计数(简单计数需求)。
  4. 玩具/模型控制:遥控玩具位置触发、模型车赛道检测等。

五、封装与使用注意事项

  1. 封装形式:型号后缀「DIP」表明采用双列直插式封装,适合手工焊接或插件安装,便于PCB板固定。
  2. 使用注意:
    • 发射端驱动:串联限流电阻(如5V供电时,R≈1kΩ),控制正向电流5-10mA。
    • 接收端偏置:搭配1kΩ左右集电极电阻,确保输出信号清晰。
    • 光路对准:发射端与接收端需对齐,偏移过大可能导致检测失效。
    • 环境限制:避免高温(>85℃)、高湿环境长期使用,防止性能下降。

XL-ITR8402作为入门级对射式光电开关,凭借高性价比、稳定可靠的特性,成为常规电子应用的首选,可有效替代机械开关,提升设备智能化水平。

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
