E3S-R2B41 Application Field and Working Principle

Optical sensors, also known as light sensors, are devices and systems that are used to detect the presence of a visible form of light, or light with specific wavelengths. Photoelectric, industrial and medical applications are often used to detect or identify objects. E3S-R2B41 is one type of industrial optical sensor designed specifically for applications in assembly lines fed by conveyors.The E3S-R2B41 is a type of photoelectric sensor in an enclosed housing, allowing for detection of objects in a wide range of conditions. With its built-in amplifier, it also allows for detection of objects in areas with limited space. These sensors are designed to detect a variety of objects, including paper, metal, wood, plastic, and glass.The E3S-R2B41 is a two-wire device, requiring a single power source for operation, thus making it a cost-effective solution for industrial applications. The sensor also supports a variety of mounting styles, making it easy to set up and use in a variety of areas and situations.In order to operate the E3S-R2B41, a configuration needs to be set up using the two output wires. Each wire is to be connected to the power supply using the appropriate voltage and current, and a signal oscillator circuit is also necessary. Once the wiring is complete, the end user can then set up the specific application settings using the rear of the unit. This setup part of the process includes setting the threshold value, detection mode and other parameters.Once the configuration is complete, the device will begin operation. The E3S-R2B41 uses infrared LED and a receiver to detect the presence of objects in the scene. The photoelectric sensor operates in two detection modes: dark ON and bright ON. In the dark ON detection mode, the LED is used to illuminate the scene and the receiver will detect the presence of objects that reflect, absorb, or emit a light signal.On the other hand, in bright ON detection mode, the infrared LED is turned off and the receiver will detect the presence of objects that do not reflect, absorb, or emit a light signal. The detection range can be adjusted as well, allowing the user to optimize the detection of objects with different properties such as size, texture, feature, and more. The E3S-R2B41 can also be programmed for automatic reset, allowing the sensor to reset itself when an object is removed from the detection area.Overall, the E3S-R2B41 is a cost-effective and easy to install solution for applications that require detection of a wide variety of objects. It\'s reliable and rugged construction makes it well suited for industrial applications, and its adjustable settings allow for further customization and optimization for various detection scenarios.
