What are the main functions of the proximity sensor?

At present, proximity sensors are widely used in various industries such as aerospace, industrial production, transportation, consumer electronics, etc. Here are some typical application scenarios, so that you can open them in the application design of proximity sensors.

    1. Check the distance to detect the stopping, starting and passing positions of elevators and lifting equipment; detect the position of the vehicle to prevent two objects from colliding; detect the set position of the working machine, the limit position of the moving machine or component; detect the stop of the rotating body Position, the open or closed position of the valve; detect the movement position of the piston in the cylinder or hydraulic cylinder.

    2. Dimension control The size control device for metal sheet punching and shearing; automatic selection and identification of the length of metal parts; detection of the height of the stack during automatic loading and unloading; detection of the length, width, height and volume of the article.

    3. Check whether the object exists or not. Check whether there is a product packing box on the production packaging line; check whether there are product parts.

    4. Rotation speed and speed control control the speed of the conveyor belt; control the speed of rotating machinery; control the speed and number of revolutions together with various pulse generators.

    5. Counting and controlling the number of products flowing through the production line; measuring the number of revolutions of high-speed rotating shafts or discs; counting parts.

    6. Detection of abnormality, detecting the presence of bottle caps; determining whether the product is qualified or unqualified; detecting the lack of metal products in the packaging box; distinguishing metal and non-metal parts; detecting whether the product has a label; the crane dangerous area alarm; the safety escalator automatically starts stop.

    7. Automatic measurement of measurement control products or parts; control the number or flow rate by detecting the pointer range of the meter and the meter; detecting the buoy to control the measuring surface height and flow; detecting the iron buoy in the stainless steel barrel; the control of the upper or lower limit of the instrument range; Flow control, level control.

    8. The recognition object recognizes right and wrong according to the code on the carrier.

    9. Information transmission ASI (bus) connects the data transmission of sensors at various positions on the equipment in the production line (50-100 meters), etc.

Application of human proximity sensor in ATM teller machine monitoring The human proximity sensor is a control device used to detect the proximity of the human body. It can accurately detect the proximity of nearby people and is currently the best choice for alarm and status detection. Its sensing part has a high detection sensitivity to the movement of nearby people, and suppresses the sound signal of the surrounding environment, and has a strong anti-interference ability. The internal microcircuit chip is used for program control processing, which has high detection sensitivity and trigger reliability. The detection and control parts are combined into one, the waiting power consumption is low, and the switch signal output directly triggers the alarm recording.

Since the sensitivity of human body induction is continuously adjustable, this makes the human body proximity sensor suitable for many different occasions. In terms of security and anti-theft, such important places as data files, accounting, finance, museums, and vaults are usually equipped with anti-theft devices composed of various proximity sensors.
