German FEDIST sensor FEDIST model FEDIST price

FEDIST sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and have been widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, applied in smart belts. Distance sensors can be classified into optical distance sensors, infrared distance sensors, ultrasonic distance sensors, and others based on their working principles. Most distance sensors used in mobile phones are infrared distance sensors, which feature an infrared emitting tube and an infrared receiving tube. When the infrared light emitted by the transmitting tube is received by the receiving tube, it indicates a close distance, requiring the screen to be turned off to prevent accidental operations. When the receiving tube does not receive the infrared light emitted by the transmitting tube, it indicates a far distance, and the screen does not need to be turned off. The working principles of other types of distance sensors are similar; they determine distance by emitting and receiving a substance, such as ultrasonic waves or light pulses.

FEDIST sensor applications

The most widespread application of distance sensors is in mobile phones. Smartphones on the market all contain distance sensors. When a user answers a call, the phone is close to the ear, making accidental operations likely (such as hanging up due to cheek contact while laughing). Therefore, the distance sensor monitors the distance in real time and automatically turns off the screen when the distance is too close to avoid accidental operations. In addition, distance sensors are widely used for measuring mine shaft depth, detecting aircraft altitude, and exploring outdoor environments. With continuous technological development, they also show prominent performance in wearable devices (such as smart belts).

FEDIST sensor working principle

When time-of-flight laser sensors operate. Time-of-flight laser sensors must measure transmission time with extreme precision because the speed of light is very fast. For example, the speed of light is approximately 3´108m/s. To achieve a resolution of 1mm, the electronic circuit of the transmission time ranging sensor must be able to distinguish the following extremely short time: 0.001m¸(3´108m/s)=3ps. Distinguishing a time of 3ps places excessive demands on electronic technology, resulting in high implementation costs. However, today's affordable time-of-flight laser sensors cleverly bypass this obstacle by using a simple statistical principle, namely the averaging rule, to achieve a resolution of 1mm while ensuring response speed.

FEDIST sensor industry applications

1) Application in taxi meter testing systems: To further promote energy conservation and emission reduction and address the metering needs of the electric vehicle industry, the mobile electric taxi meter testing system has been officially launched. The testing device is roughly divided into two parts: a main unit about the size of a password box placed on the rear seat of the car, and a distance sensor attached to the car body. According to reports, the device uses the driving distance measurement method. As the driver drives a certain distance, the testing device and the meter sample synchronously. The entire testing process is expected to be completed in seven to eight minutes. 2) Wide applications in the automation field: Currently, in addition to ultrasonic sensors and standard photoelectric sensors, a new method capable of solving long-distance measurement and inspection has been added to automatic detection and control methods—the time-of-flight laser distance sensor. It provides application flexibility for various occasions, including the following: (1) Equipment positioning. (2) Measuring the material level in bags. (3) Measuring object distance and object height on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection occasions. (7) Aircraft ground clearance monitoring.
