XL-ITR9909 是成兴光(Xinglight)推出的一款反射式光电开关,采用插件式 DIP-4 封装(尺寸 8.7×4.5mm)。器件由红外发光二极管(LED,λ=940nm)与光电三极管组合而成,输出为光电三极管型,适合用于非接触式反射物体检测与位置感知场合。器件响应速度快、驱动电流范围宽、封装紧凑,便于穿孔安装与电路集成。
典型 DIP-4 引脚(建议在最终设计中以器件实物/数据手册为准):
典型驱动与读取电路:使用单电源 VCC(如 5V)驱动 LED,串联限流电阻 RLED=(VCC−Vf)/If。例:VCC=5V, 目标 If=20mA,则 RLED≈(5−1.2)/0.02≈190Ω(取 180–220Ω)。光电三极管可做开集电极输出,外接上拉电阻 Rpull(常用 4.7k–100kΩ,典型 10kΩ),R 值越小响应越快但功耗增加。
品牌:Xinglight(成兴光);型号:XL-ITR9909;封装:插件式 DIP-4。采购时建议向供应商索取完整数据手册与样品,确认针脚排列与电气特性以便顺利集成。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
