QRD1313数据手册传感器变送器的光学传感器-反射式-模拟输出规格书PDF

描述 Description

The QRD1313 reflective sensor consists of an infrared emitting diode and an NPN silicon photodarlington mounted side by side in a black plastic housing. The on-axis radiation of the emitter and the on-axis response of the detector are both perpendicular to the face of the QRD1313. The photodarlington responds to radiation emitted from the diode only when a reflective object or surface is in the field of view of the detector.

特性 Features

■ Photodarlington output
■ Unfocused for sensing diffused surfaces
■ Low cost plastic housing
■ Designed for paper path and other non-contact surface sensing 

简介

QRD1313属于传感器变送器的光学传感器-反射式-模拟输出。由制造生产的QRD1313光学传感器 - 反射式 - 模拟输出模拟输出反射式光学传感器产品族中的产品包含彼此相邻并朝向相同方向安装的光发射器和光敏元件（通常是光电晶体管），以便确保发射器发出的光在传感器视场中被物体反射时可以被设备内的传感元件检测到。这种类型的模拟输出传感器以最少的处理量直接传送由光电传感器产生的信号，同时用户需要提供自己的解释机制来确定物体检测结果。
