A1101LUA-T 是 Allegro(美国埃戈罗)推出的一款小型高可靠性的霍尔效应磁敏开关。器件采用 TO-92(SIP3)直插封装、适合 PCB 插装,面向位置、接近和速度检测等低成本、耐用的磁感应场合。器件以数字开关形式输出,对磁场有明确的动作阈值,适合替代机械接点实现无接触开关功能。
A1101LUA-T 采用常见的 TO-92 小型三脚直插封装(SIP3),便于在通用 PCB 上布局。标准引脚排列可用于直接替换同类直插霍尔开关。建议在 PCB 布局时预留足够的焊盘和散热空间,并按厂商资料核对引脚定义(Vcc、GND、OUT)。
在选型时应重点确认:动作/释放磁场(Gs)、输出类型(开路/推挽)、工作电压范围与工作温度。A1101LUA-T 属于通用单极霍尔开关系列,若需要更高灵敏度、更宽温度或不同输出驱动能力,可参考 Allegro 的其它 A110x 系列或同行厂商的等效型号。批量采购时请向供应商核实元件的灵敏度等级和出厂测试条件。
总结:A1101LUA-T 以其小巧的 TO-92 封装、宽广的工作电压范围与可靠的霍尔开关特性,适合多种工业与消费类无接点磁性检测应用。选型与设计时关注磁场强度与极性、供电去耦与输出接口形式,可获得稳定、长期可靠的检测性能。若需完整电气参数与典型波形,请参考 Allegro 官方数据手册。

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.
