ALS-PT243-3C/L177 光电传感器产品概述

这款来自台湾亿光(Everlight Electronics Co Ltd)的ALS-PT243-3C/L177,是一款针对630nm红光波段设计的有源径向通孔型光电传感器。作为亿光常规光电器件系列的一员,它凭借精准的波长响应、低噪声特性和宽温适应性,成为工业自动化、消费电子等领域光检测场景的实用选择。

一、核心身份与基本定位

ALS-PT243-3C/L177属于有源光电传感器(无需额外偏置电路即可工作),核心功能是对特定波长的光信号进行检测转换。其明确的630nm波长响应,聚焦于红光波段的精准识别,可有效过滤其他可见光(如绿、蓝光)的干扰,提升检测针对性。

二、关键性能参数深度解析

2.1 波长与光谱特性

峰值响应波长为630nm,属于可见光中的红光波段,与常见红光LED(如亿光IR333-A系列)的发射波长匹配度高,适合红光光源的检测、红光信号的传输验证等场景。

2.2 电气性能

  • 暗电流(Id)最大值100nA:暗电流是器件无光照时的漏电流,100nA的低阈值意味着弱光环境下自身噪声极小,信号与噪声比(SNR)更高,检测精度和灵敏度更优;
  • 集射极击穿电压(最大值)5.5V:确保器件在正常工作电压范围内(通常3~5V)不会被击穿,电路设计时无需额外配置过压保护电路,简化系统设计。

2.3 环境适应性

工作温度范围为**-40°C ~ 85°C**,覆盖工业级环境要求:既能应对户外设备的低温(如冬季户外监测),也能适应设备内部的高温散热(如工业控制器内部),环境兼容性强。

三、封装与安装特性

3.1 封装形式

采用径向通孔封装(径向引脚布局),属于常规通孔封装类型,无需特殊贴装设备即可安装,适合小批量原型开发或量产需求。

3.2 安装便捷性

  • 通孔安装:支持手工焊接或波峰焊工艺,与常规PCB设计兼容;
  • 径向引脚:引脚呈对称径向分布,光接收面可根据场景需求调整角度(如垂直或水平安装),适配不同光入射方向;
  • 包装方式:袋装包装,方便取用、库存管理和批量生产中的分拣。

四、典型应用场景

ALS-PT243-3C/L177的红光响应特性和宽温适应性,使其适用于以下场景:

  1. 红光光源检测:验证红光LED的发光状态、检测红光信号的传输强度(如光纤红光信号检测);
  2. 光电开关系统:与红光发射管配合,组成对射式/反射式光电开关,用于流水线物体计数(如金属件、红色标签)、位置检测(如机械臂终点定位);
  3. 工业自动化监测:检测设备的红光警示信号(如故障指示灯)、监控生产线中红光标记的物体;
  4. 消费电子辅助:小型设备的光控功能(如红光触发的开关、红光亮度调节检测);
  5. 户外设备应用:因宽温范围,可用于户外光信号检测(如交通警示灯的红光状态监测)。

五、总结

ALS-PT243-3C/L177以精准红光响应、低暗电流、宽温工作为核心优势,结合便捷的径向通孔封装,适配多类光检测与控制场景。作为亿光的成熟器件,其可靠性和兼容性已在工业、消费电子等领域得到验证,是需要红光波段检测的系统设计的实用选择。

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
