Optical sensors are an important component of most industrial applications. They are used to measure and detect the presence of physical objects in a variety of ways. A particularly popular type of optical sensor is the 70156-4164, which is used in a wide range of applications. This article will explore the application field and working principle of the 70156-4164.The 70156-4164 is an industrial light sensor designed for applications in industrial automation systems. As a photoelectric sensor, it is used to detect the presence of objects in a specific area by detecting changes in the light level or in the light intensity. In order to detect these changes, the sensor uses an integrated optical detector, such as a photoresistor, and an integrated amplifier circuit. When an object is present in the area of detection, the optical system will detect changes in the light levels and the amplifier circuit will amplify the signals and pass them to the control system. The control system then interprets the data from the sensor and takes the appropriate action.The 70156-4164 is suitable for use in a wide range of applications, including machine vision and assembly line automation. It is also used in robotic applications, where it is used to detect objects and take action accordingly.There are two primary methods used for measuring light intensity with the 70156-4164. The first is a direct current detection, which uses a current source to measure the current generated by a photoresistor. This method is typically used when a uniform light intensity needs to be measured over a wide area. The second method is a voltage mode detection, which uses a voltage source to measure the voltage generated by a photoresistor. This is typically used when a specific area or a specific light source needs to be measured.In the case of voltage detection, the 70156-4164 uses an external power supply to provide a reference voltage for the amplifier circuit, which allows for more accurate measurement of the voltage generated by the photoresistor. The voltage generated by the photoresistor is then compared to the reference voltage and the output signal is amplified allowing for the detection of changes in the light intensity or in the light level.The 70156-4164 also has the ability to detect changes in the light intensity in two modes. The first mode is referred to as peak detection mode, which is used when the light intensity needs to be detected at a specific point in time. The second mode is referred to as count detection mode, which is used when the light intensity needs to be detected over a period of time. In peak detection mode, the sensor will detect the peak light level and then ignore it until the peak has passed, whereas in count detection mode the sensor will detect each peak and store the light intensity in a counter for later analysis.The 70156-4164 is a reliable, accurate and effective photoelectric sensor for a wide range of applications. It can be used for both direct current and voltage detects and can detect changes in the light intensity in both peak and count detection modes. Additionally, it can be easily integrated into an existing system, making it an ideal choice for industrial applications.
