FD-S31: Application Field and Working Principle

Optical sensors find broad applications in many industries. One of the most versatile and widely used is the FD-S31 photoelectric, industrial sensor. It is a digital, self-contained optical sensor designed to detect the presence or absence of an object and measure the distance of that object to precisely locate and identify its position in numerous industrial environments. This article explains the application field and working principle of the FD-S31 in detail.

Application Field

The FD-S31 photoelectric, industrial sensor is a popular choice for many applications due to its versatile features. It can be used for position sensing, presence detection, product counting, and identification as well as range finding. Its main use is in factory automation, including robotics, automatic manufacturing, and quality control in various industries. Its wide application fields include automotive production lines, assembly machines, material handling systems, and warehouse management. The spot size of the FD-S31 is adjustable, and the light emission can easily be adjustable from 0 to 1880 mm. It is also capable of detecting objects of different sizes and shapes, such as paper, cardboard, and metal. This makes it suitable for a diverse range of applications such as level detection, proximity detection, and part counting. It can also be used in process machines, assembly lines, and packaging systems.

Working Principle

The FD-S31 photoelectric, industrial sensor operates by emitting small spot infrared light and then detecting the light reflected from its reflective target. This working principle is called the triangulation principle. The FD-S31 utilizes two emitters and one receiver. The emitters are made up of light-emitting diodes. They emit light of a specific wavelength that is generally invisible to the human eye. The receiver is made up of a light detector. It receives the infrared light that is reflected from the target object and is then used to compute the distance to the target object. This triangulation principle ensures that the FD-S31 can identify and accurately measure the distance of a target object from a precise position. It is also capable of measuring the distance of an object from multiple locations for applications such as automated handling and product counting where multiple sensors are required. The FD-S31 is easy to setup and operate due to the use of push-button setup and LED status indicator. Its quick installation and operations help to reduce downtime and increase efficiency in production. It is also designed with output modes of two-wire or three-wire operation, enabling its use with different control systems with ease.

Conclusion

The FD-S31 photoelectric, industrial sensor is a versatile, digital, and self-contained optical sensor with wide application in various industrial environments. Its ability to detect objects of various sizes and shapes makes it suitable for many applications. It is easy to setup and operate, and its triangulation principle ensures that it can accurately measure the distance of an object to precisely locate and identify its position.
