SIEMENS 6DS1723-8BA是一种光电传感器，主要用于检测光信号并将其转换为电信号。这种传感器既可用于检测光强、光照度、辐射测温、气体成分分析等可直接引起光量变化的非电量，也可用于检测零件直径、表面粗糙度、应变、位移等可间接转换为光量变化的非电量。由于光电传感器具有性能高、响应快、非接触等诸多特点，在工业自动化装置及机器人领域都有着重要的应用，特别是近年来图像传感器的产生，为光电传感器的进一步发展开辟了新篇章。

光电传感器主要由发送器、接收器、检测电路三大部分构成。其中，发送器用于对准半导体光源、发光二极管、激光二极管、红外发射二极管等发出的目标光束；接收器又可分为光电二极管、光电三极管、光电池等，在接收器前面还装有透镜、光圈等光学元件，主要用于接收目标光束并将接收到的光信号转换为电信号；检测电路用于检测接收到的电信号并过滤出有效信号，将其传递至下一模块进行该电信号的实际应用。

It is a photoelectric sensor mainly used to detect optical signals and convert them into electrical signals. This type of sensor can be used to detect non electrical quantities that can directly cause changes in light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc., as well as non electrical quantities that can be indirectly converted into changes in light quantity, such as part diameter, surface roughness, strain, displacement, etc. Due to the high performance, fast response, and non-contact characteristics of photoelectric sensors, they have important applications in industrial automation devices and robotics. Especially in recent years, the emergence of image sensors has opened up a new chapter for the further development of photoelectric sensors.

Photoelectric sensors are mainly composed of three parts: a transmitter, a receiver, and a detection circuit. Among them, the transmitter is used to aim the target beam emitted by semiconductor light sources, light-emitting diodes, laser diodes, infrared emitting diodes, etc; The receiver can also be divided into photodiodes, photodiodes, photocells, etc. There are also optical components such as lenses and apertures installed in front of the receiver, mainly used to receive the target beam of light and convert the received optical signal into electrical signals; The detection circuit is used to detect the received electrical signal, filter out the effective signal, and transmit it to the next module for practical application of the electrical signal.
