Optical Sensors come in many forms, from Photoelectric Sensors, Industrial Sensors, to ET4-P4238. This article aims to discuss the ET4-P4238 Sensor Application Field and Working Principle.

ET4-P4238 is a Photoelectric Sensor which is designed for space-saving mounting distances. It features a high-speed response time of 4.2 ms and a wide visible operation range of 1.5 to 5 m. The optics casing is made of 17mm high efficient polymer material, providing excellent response abilities and longer service life. In addition, the Sensor features a microcontroller and a light-transmitting circuit that operates in a two-channel and two-step process. This ensures that the Sensor quickly adjusts the proportion of light intensity during signals and ultimately produces reliable responses.

The ET4-P4238 Sensor is mainly used in industrial automation applications. Its compact design makes for enhanced stability in production line automation. For example, it is ideal for employing in labeling machines, printing equipment, and robot arms. Additionally, it can be used for presence detection in assembly lines and in pick-and-place applications, allowing for more accurate and efficient production. In addition, its built-in and long-range adjacent infrared light technology makes it well suited for liquid and material level control.

In terms of its working principle, the ET4-P4238 works by reflection modulating technique. In this system, a beam of light emitted by a special emitter is modulated through the reflected light beam after it passes through a surface or object. The signal is then captured by the microcontroller and the light-transmission circuit. By comparing the amplitude of the received signal with a predetermined value, the Sensor then makes the determination whether or not there is an object present. If there is an object, the Sensor adjusts the proportion of light intensity of its light transmission circuit and produces a response.

To summarise, the ET4-P4238 Sensor is a Photoelectric Sensor designed for space-saving mounting distances. It features a high-speed response time of 4.2 ms and a wide visible operation range of 1.5 to 5 m. The ET4-P4238 Sensor is mainly used in industrial automation applications and its working principle is based on reflection modulating technique. With its built-in and long-range adjacent infrared light technology, the ET4-P4238 Sensor is ideal for presence detection, material level control, and other applications.
