XL-ITR1203D 对射式光电开关 — 产品概述

XL-ITR1203D(成兴光 Xinglight)是一款插件封装的对射式红外光电开关,内置940nm发光二极管(IR LED)与光敏接收器(光电晶体管)对射结构。器件体积小巧(长7.5mm × 宽2.8mm × 高6.3mm),适合各种位置、计数、挡光检测和物体存在/缺失检测等应用,具有快速响应、抗干扰性好和易于安装的特点。

一、主要特性

  • 对射式结构,发射端与接收端成直线对射,检测更加稳定可靠。
  • 峰值波长:940nm(红外),对常见遮挡体具有良好穿透与识别能力。
  • 典型响应时间:上升时间 tr = 15 μs,下降时间 tf = 15 μs,支持约 20–25 kHz 的开关频率应用。
  • 额定负载电压(最大):30 V;输出允许负载电流:20 mA。
  • 暗电流低:100 nA,漏电小,空闲状态误触发概率低。
  • 发光二极管正向压降 Vf = 1.2 V(典型)。
  • 工作温度范围:-25 ℃ ~ +85 ℃。
  • 插件(through-hole)封装,便于手工与波峰/回流焊安装。

二、主要规格参数(摘要)

  • 槽宽(器件外型):5.0 mm
  • 缝隙/检测间隙:0.5 mm(被检测物体只要达到该遮挡宽度即可明显触发)
  • 峰值波长:940 nm
  • 上升/下降时间:15 μs / 15 μs
  • 最大负载电压:30 V
  • 最大负载电流:20 mA
  • 暗电流:100 nA
  • LED 正向压降:1.2 V(典型)
  • 封装尺寸:7.5 × 2.8 × 6.3 mm
  • 工作温度:-25 ℃ ~ +85 ℃

三、电气接口与典型接法

  • 发射管(IR LED)驱动:推荐典型正向电流 10–20 mA,若使用 20 mA 驱动,请按下列公式选择限流电阻:R = (Vcc - Vf) / If。
    • 例:Vcc = 5 V 时,R ≈ (5 - 1.2) / 0.02 ≈ 190 Ω(可选 180 Ω 或 200 Ω)。
    • Vcc = 12 V 时,R ≈ 560 Ω;Vcc = 30 V 时,R ≈ 1.5 kΩ(注意功耗)。
  • 接收端(光电晶体管)通常作为开路集电极输出,需外接上拉电阻到检测电源或逻辑电平。上拉电阻值影响响应速度与电流消耗:
    • 若需高速开关(接近器件极限 15 μs),上拉电阻取较小值(几百欧至 1 kΩ);
    • 若以低功耗为主,可采用 10 kΩ–100 kΩ,但过大可能受暗电流和环境光影响。
  • 建议尽量把接收端上拉至与后级逻辑相同的电压(如 5 V 或 3.3 V),避免直接上拉到 30 V,以降低功耗与器件应力。

四、性能说明与应用场景

  • 响应速度(tr/tf = 15 μs)使本器件适用于编码盘、转速检测、计数器、纸张/薄膜断点检测或物体微小间隙检测等中高速场景。理论上可检测约 20–25 kHz 的方波信号。
  • 暗电流仅 100 nA,意味着在无光照时输出非常稳定,适合对误动作敏感的场合。
  • 0.5 mm 的缝隙宽度提示可检测较小的遮挡物,配合 5 mm 的槽宽与标准机械定位,可实现重复性好的检测。
  • 典型应用:打印机纸张检测、自动化装配线计数、料带/皮带上位置检测、限位/行程检测和消费类电子中的遮挡检知等。

五、机械安装与对准建议

  • 插件安装时确保发射端与接收端准确对齐,光路不可偏移;可在外壳上设计定位柱或卡槽,保证长期对准。
  • 被测物体通过时应尽量垂直于光轴通过缝隙,避免斜穿导致信号不稳定。
  • 若环境光强(如直射太阳或强白光),建议加挡板、滤光片或使用调制驱动与同步解调以提高抗干扰能力。

六、注意事项与选型建议

  • 发射LED驱动电流不可长期超出器件额定值(建议 ≤ 20 mA),以免降低寿命或引起热失配。
  • 若系统电源为高压(如 12 V、24 V、30 V),尽量把 LED 限流与接收上拉电阻按功率等级选型,必要时采用分立限流器或恒流源。
  • 对要求极高速度或更低暗电流的场合,可选用专用高速光敏器件或光电晶体管-放大器模块。
  • 存储与使用时注意防静电,避免阳光或强近红外光直射,延长使用寿命。

七、常见故障排查提示

  • 无输出或始终低:检查 LED 驱动电路与限流电阻是否断路、LED 极性是否正确。
  • 输出漂移/误触发:检查环境光照、上拉电阻是否过大或接线是否存在噪声耦合。
  • 响应慢或不稳定:确认上拉电阻值不宜过大;若需更快响应可适当降低上拉阻值或增加 LED 驱动电流(在安全范围内)。

品牌与型号:Xinglight(成兴光) XL-ITR1203D。该器件以体积小、响应快、对射稳定著称,适合多种定位与遮挡检测场合。若有具体应用电路或环境(供电电压、检测距离、被测物形状)可提供更针对性的驱动与上拉电阻建议。

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.
