Germany ACAM sensor ACAM model ACAM price

ACAM 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 divided 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 have 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 that the distance is close, and the screen needs to be turned off to avoid accidental operation. When the receiving tube does not receive the infrared light emitted by the transmitting tube, it indicates that the distance is far, and there is no need to turn off the screen. The working principles of other types of proximity sensors are similar; they also judge the distance by the emission and reception of some substance, such as ultrasonic waves, light pulses, etc.

ACAM sensor applications

The most widespread application of distance sensors is in mobile phones. Smartphones on the market all contain distance sensors. When a user makes or receives a call, the phone is close to the ear, which can easily lead to accidental operations (for example, cheeks puffing out when laughing may hang up the call). Therefore, a distance sensor is required to monitor the distance in real time and automatically turn off the screen when the distance is too close, thereby preventing accidental operations. In addition, distance sensors are also widely used for measuring mine shaft depth, detecting aircraft altitude, and exploring outdoor environments. With the continuous development of technology, they also show prominent performance in wearable devices (such as smart belts).

ACAM sensor working principle

When the time-of-flight laser sensor is operating. The time-of-flight laser sensor must measure the 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 distinguish the following extremely short time: 0.001m¸(3´108m/s)=3ps. Distinguishing a time of 3ps places excessive demands on electronic technology, making implementation too costly. However, today's inexpensive time-of-flight laser sensors cleverly avoid this obstacle by using a simple statistical principle, namely the law of averages, to achieve a resolution of 1mm while ensuring response speed.

ACAM 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: one is a main unit about the size of a briefcase, placed on the rear seat of the car, and the other is a distance sensor attached to the car body. According to reports, the device uses the driving distance measurement method. As the driver drives the car for 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 field of automation: Nowadays, in addition to ultrasonic sensors and conventional photoelectric sensors, a new method capable of solving long-distance measurement and inspection has been added to automatic detection and control methods—time-of-flight laser distance sensors. They provide application flexibility for various scenarios, including the following: (1) Equipment positioning. (2) Measuring the material level of material packages. (3) Measuring the distance and height of objects on conveyor belts. (4) Measuring log diameter. (5) Protecting overhead cranes from collisions. (6) Error-free inspection scenarios. (7) Monitoring aircraft ground clearance.
