Optical sensors are devices that convert light or the absence of light into an electrical signal. They can detect a wide range of wavelengths, from visible to infrared to ultraviolet. The most common type of optical sensor is the photoelectric sensor, which is used in many industrial and commercial applications. Another type of optical sensor is the industrial sensor, which is used in manufacturing and process control. The FD-31 application field and working principle are discussed below.

FD-31 Application Field

The FD-31 is a compact, rugged, and affordable photoelectric sensor designed for use in industrial applications. The FD-31 is most commonly used for object detection, tracking, and positioning, as well as many other automated tasks. It is also used for detecting the presence or absence of targets, including objects, people, and animals. The FD-31 can be used with a wide range of analog and digital inputs, providing reliable performance in challenging industrial environments. The FD-31 also has a built-in red LED indicator that can be programmed to indicate the state of the sensor.

The FD-31 is suitable for a variety of industrial applications, such as machine automation, process control, and robotics. It is also used in industrial automation systems for motion tracking and positioning. The FD-31 is particularly well-suited for applications in high-pressure, dust-filled, and/or vibration-prone environments, as it is made of rugged materials and its design can withstand severe shock and vibration.

FD-31 Working Principle

The working principle of the FD-31 is based on the reflection of light. The sensor emits a modulated, infrared light beam, which is reflected back to the sensor by the target object. The sensor then measures the intensity of the reflected light, and this data is then sent to the appropriate logic unit in the automated system for further processing. The FD-31 is designed with adjustable switching points for optimal sensitivity, allowing it to effectively detect a range of objects and environments.

The FD-31 also has a built-in timer, which can be programmed to limit the number of objects that can be detected. This timer is used to prevent the sensor from overloading due to too many objects entering the scanning area. With the FD-31, users can also select between normally-open and normally-closed outputs. This feature allows for flexible and customized applications.

The FD-31 is a reliable and economical photoelectric sensor that can be used in a wide range of industrial applications. It is designed for robustness and stability, with adjustable switching points for maximum sensitivity and a timer for object detection. It is also easy to install and use, making it an ideal choice for industrial automation.
