Working principle of proximity switch P1-D25PK; U: DC 10-36V switches are sometimes called inductive proximity switches. It utilizes a conductive object to generate eddy currents inside the object when approaching a proximity switch that can generate an electromagnetic field. This eddy current reacts on the proximity switch, causing changes in the internal circuit parameters of the switch, thereby identifying whether a conductive object is moving closer and controlling the on or off of the switch. The object that can be detected by this proximity switch must be a conductive body. Main functions: 1. Check distance
Detect the stop, start, and passing positions of elevators and lifting equipment; Detecting the position of the vehicle to prevent collision between two objects; Check the set position of the working machinery and the limit position of the moving machine or component; Detect the stop position of the rotating body and the open or closed position of the valve< br />2、 Size control device for metal plate punching and shearing; Automatically select and identify the length of metal parts; Detecting the stacking level during automatic loading and unloading; Detect the length, width, and volume of items. Check for the presence of objects, check for product packaging boxes on the packaging line; Check for product parts< br />3、 Speed and speed control control the speed of the conveyor belt; Control the rotational speed of rotating machinery; Control the speed and number of revolutions together with various pulse generators< br />4、 Counting and controlling the number of products passed by the detection line; Measurement of the number of revolutions of a rotating shaft or disc; Component count< br />5、 Abnormal detection
Check if the bottle cap is present; Product qualification and non conformity judgment; Check if there is a lack of metal products inside the packaging box; Distinguish between metallic and non-metallic parts; Whether the product has a label inspection; Crane danger zone baojing; Anquan escalator automatically starts and stops< br />6、 Measurement control
Automatic measurement of products or parts; Control the number or flow rate by detecting the pointer range of measuring instruments and meters; Detecting buoys to control surface accuracy and flow rate; Detecting iron buoys in stainless steel drums; Control of the upper or lower range of the instrument; Flow control, horizontal control< br />7、 Identify objects based on the code on the carrier to identify right and wrong< br />8、 Information transmission: ASI (bus) connects sensors at various positions on the device to transmit data back and forth in the online (50-100 meters). Working principle of proximity switch P1-D25PK; U:DC 10-36V1、 For different materials of detection bodies and detection distances, different types of proximity switches should be selected to achieve better performance in the system. Therefore, the following principles should be followed in selection: 1.1. When the detection body is made of metal materials, frequency oscillation type proximity switches should be selected, which are sensitive to detection of iron nickel and A3 steel. The sensitivity of aluminum, brass, and stainless steel detection bodies is high. 1.2. When the detection body is made of non-metallic materials, such as; Capacitive proximity switches should be used for materials such as wood, paper, plastic, glass, and water. 1.3. When metal and non-metal materials need to be detected and controlled remotely, photoelectric proximity switches or Chaoshengbo proximity switches should be selected. 1.4. When the detection body is metal, if the detection sensitivity is required from time to time, Jiege's magnetic proximity switch or Hall type proximity switch can be selected. So  nine hundred
