Optical sensors, due to their non-invasive nature, are one of the most preferred types of sensors used in industrial applications. The E3T-FD13M is a lightweight, highly reliable, and versatile optical sensor developed by Omron. It is a compact, liquid-proof, and cost-effective photoelectric sensor, designed to work in difficult industrial environments. This article aims to discuss the application field and working principle of E3T-FD13M.

Application Field of E3T-FD13M

The E3T-FD13M is designed specifically for use in industrial applications where durability and reliability are paramount. This photoelectric sensor is suitable for a wide variety of applications, ranging from factory automation to material handling, packaging, and conveyor belt systems. It is also ideal for mounting in tight spaces, due to its slim body and U-bracket design. The integrated red LED light source offers a long range and the ability to detect small objects, making it a great choice for applications requiring high-speed responses. The U-bracket can also be adjusted to suit various mounting angles, and the IP67 rating allows for use in wet and dust-prone environments.

The E3T-FD13M also comes with a range of improved features over its predecessor, such as an extended sensing distance of 5m, improved light spot size, and superior repeat accuracy. Additionally, the photoelectric sensor is equipped with an "easy setup" mode that allows users to quickly and easily set up the device within minutes. This mode eliminates the need for complex settings and parameters and makes the device easy to use for even novice users.

Working Principle of E3T-FD13M

The E3T-FD13M is a normal open-type photoelectric sensor and utilizes an infrared (IR) light source. The IR light source is emitted at an angle of 20 degrees, and when an object changes the light field, the sensor detects the change and triggers the output signal. This trigger can be used to set up the device to count items passing through the light field or to trigger devices such as conveyor belts, packing machines, and sorting systems.

The output signal is triggered by the sensor when a target enters the sensing field. The output signal can be set to one of two states, depending on the type of output configuration chosen: Normal On or Normal Off. In Normal On mode, the output signal is triggered when an object passes through the light beam, and in Normal Off mode, the output signal is triggered when the object leaves the light beam. This allows for more accurate detection, as the system can be set to detect objects travelling in either direction.

The E3T-FD13M is designed to minimize false triggering and minimize response time. This is achieved by the use of a diffused light spot, which reduces sensitivity to ambient light changes and minute vibration. Additionally, the device is equipped with a built-in self-diagnostic feature that alerts the user if the output is blocked or if the sensing distance is outside of its specified range.

The E3T-FD13M is a highly reliable and versatile photoelectric sensor for use in industrial applications. Its wide range of features, including long sensing distance, superior repeat accuracy, and easy set-up mode make it a great choice for a variety of applications. The compact size and rugged construction make it perfect for applications in tight spaces and harsh environments.
