Introduction

E3S-2LE4 is an optical sensor manufactured by Omron, a leading automation and sensing technology provider. It is designed for use in various industrial automation applications. It is a multi-function photoelectric sensor that is capable of detecting objects in a variety of industrial conditions, and is used to measure displacement, position, and velocity in positioning, cutting, and automation systems.

E3S-2LE4 Application Field and Working Principle

The E3S-2LE4 provides an efficient, reliable, and cost-effective method for detecting objects in a range of industrial settings. It can detect objects in a variety of industrial conditions, including wet, clean, and dirty applications. In addition, it is able to detect objects in a wide range of temperatures, from -25°C to +60°C (−13°F to 140°F).The E3S-2LE4 provides a variety of functions for detecting objects in different industrial settings. It has two types of detection methods, light and dark state methods, to accurately detect the presence of objects. The light state method uses an infrared emitter and receiver to detect objects utilizing internal reflection. The dark state method uses a wide-angle emitter and receiver to detect objects using external reflection.The E3S-2LE4 can also be used as a displacement sensor to detect the position of objects. This works by using two infrared emitters and two receivers. When an object is detected, the intensity of the light emitted by the two emitters and the reflected beam of the printed circuit board is sent to a built-in control unit, which then sends information to a programmable logic controller (PLC). This information is then used to accurately measure the distance between the object and the PLC system.The E3S-2LE4 is also capable of detecting the velocity of objects. It uses a built-in frequency-modulated continuous-wave (FM-CW) technique to detect objects in motion. This technique works by sending out an infrared signal at a certain frequency, and the receiver will then detect the change in frequency when an object is detected.The E3S-2LE4 can also be used to detect objects using an obstacle-detection function. This function works by sending out a signal at a certain frequency, and when an object is detected, the frequency of the signal will change. This can be used to detect objects in dangerous areas, as well as for monitoring operations in automated machinery.In addition to its detection capabilities, the E3S-2LE4 also offers various settings for operation. These settings include the selection of measurement range, modulation frequency, sensing distance, and reaction time. These settings can be easily adjusted via the device\'s intuitive user interface, and are suitable for a variety of industrial settings.

Conclusion

The E3S-2LE4 is a multi-function photoelectric sensor manufactured by Omron, and is capable of detecting objects in a wide variety of industrial conditions. It can detect objects in light and dark modes, and can also be used as a displacement sensor. Furthermore, it can detect the velocity of objects using an obstacle-detection function. With its intuitive user interface and adjustable settings, the E3S-2LE4 is ideally suited for use in a variety of industrial automation applications.
