German Nais sensor Nais model Nais price

Nais 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. Proximity sensors can be classified into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, etc., based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which consist of 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 short 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 long distance, and there is no need to turn off the screen. The working principles of other types of proximity sensors are similar; they determine distance by emitting and receiving a substance, such as ultrasonic waves or light pulses.

Nais sensor applications

The most widespread application of proximity sensors is in mobile phones. Smartphones on the market all contain proximity 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 proximity sensor monitors the distance and automatically turns off the screen when the distance is too close to avoid accidental operations. In addition, proximity 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).

Nais sensor working principle

When time-of-flight laser sensors operate. Time-of-flight laser sensors must measure transmission time extremely accurately because the speed of light is too fast. For example, the speed of light is approximately 3´108m/s. To achieve a resolution of 1mm, the electronic circuit of the time-of-flight ranging sensor must be able to resolve the following extremely short time: 0.001m¸(3´108m/s)=3ps. Resolving 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 avoid this obstacle by utilizing a simple statistical principle, namely the law of averages, to achieve a resolution of 1mm while ensuring response speed.

Nais sensor industry applications

1) Application in taxi meter testing systems: To further promote energy conservation and emission reduction and address the metrology 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 host unit about the size of a password case, placed on the back 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 range of 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—time-of-flight laser distance sensors. It provides application flexibility for various occasions, including the following: (1) Equipment positioning. (2) Measuring material level in bins. (3) Measuring object distance and height on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection scenarios. (7) Aircraft ground clearance monitoring.
