What is a proximity switch?
Proximity switch we can see from its name on what this product is used for, this product is also after continuous improvement after more and more functions, in order to let more people familiar with it, the next small make up to introduce you to the proximity switch it's some basic information? If you want to know then take a look at it, I hope to bring you help.
Proximity switch is a position switch that can be operated without direct mechanical contact with moving parts. When an object approaches the sensing surface of the switch to the action distance, the switch can be activated without mechanical contact and any pressure to actuate a DC motor. Or provide control commands to computer (plc) devices. Proximity switch is a switch type sensor (i.e. non-contact switch). With the characteristics of travel switch and microswitch, proximity switch has good sensing performance, reliable action, stable performance, fast frequency response, long service life, anti-interference and so on. Strong ability, etc., and has the characteristics of waterproof, shockproof, corrosion-resistant. The products are inductive, capacitive, Hall, AC, DC.
Proximity switch, also known as contactless proximity switch, is an ideal electronic switch sensor. When the metal detecting body is close to the sensing area of the switch, the switch can send out electrical commands quickly without contact, pressure or sparks to accurately reflect the position and travel of the motion mechanism. Even if it is used for general travel control, its positioning accuracy, operating frequency, service life, ease of installation and adjustment, and adaptability to harsh environments are incomparable to ordinary mechanical limit switches. Proximity switches are widely used in machine tools, metallurgy, chemical industry, textile, printing and other industries. In the automatic control system, it can be used as the link of limit, counting, position control and automatic protection.
In a variety of switches, there is a component with the ability to "sense" the object approaching it - the displacement sensor. The use of displacement sensors on the sensitivity of the approaching object to achieve the purpose of controlling the switch on or off, this is the proximity switch. When an object moves towards the proximity switch and approaches a certain distance, the displacement sensor can "sense" the switch action. This distance is often referred to as the "detection distance". However, different proximity switches have different detection distances. Sometimes the object to be detected moves to the proximity switch one by one at regular intervals, then moves away one by one, and so on and so forth. Different proximity switches have different responsiveness to the detected object. This response characteristic is called "response frequency".
The above article content is the proximity switch manufacturers for you to talk about the basic information of the product, I do not know if you understand it. If you still do not understand if you hurry to read it. Well, today's knowledge will be the first to say here, I hope to bring you help.
Magnetic Reed Switches vs. Reed Switches: Understanding the Difference Have you ever been confused when buying a door magnetic switch? There are two common types of door magnetic switches on the market: reed switches and reed switches. They look similar, but there are actually some important differences. Let's take a look at these two types of door magnetic switches so you can make an informed choice. First, let's focus on reed switches. Reed switches use a reed and a magnet to sense when a door is open or closed. When the door is closed, the magnet moves closer to the reed, causing it to close, which triggers the switch. And when the door is open, the distance between the magnet and the reed increases and the switch breaks. This design makes the reed switch very sensitive and responsive. In contrast, the reed switch uses a different principle of operation. It consists of a glass tube containing a steel reed inside a magnetic material. When the door is closed, the reed makes contact with the magnetic material, causing the reed switch to close. When the door is opened, the magnetic material loses its attraction and the reed springs open, disconnecting the switch. The advantage of the reed switch is its long life and ability to withstand higher current loads. So how do you choose the right door magnetic switch for you? It depends on your specific needs. If you're focused on responsiveness and sensitivity, then a reed switch may be more suitable for
Wireless Door Magnets vs. Wired Door Magnets: which one is better for you Door Magnetic Switches are a common security device widely used in homes, businesses and industries to monitor the status of doors and windows. When choosing a door magnet switch, many people are faced with a decision: to choose a wireless door magnet or a wired door magnet? This article will explore the advantages and disadvantages of both types of door magnet switches to help you make a more informed choice. Wireless door magnet refers to the door magnet switch that does not need to be connected by wires and transmits door and window status information through wireless signals. It features easy installation and simple maintenance. Since wireless door magnet does not need to lay wires, it can save time and cost during the installation process. At the same time, the wireless door magnet can monitor the status of doors and windows anytime and anywhere, and can receive information even at locations far away from the door magnet. This makes it ideal for remote monitoring and security systems. However, wired door magnets also have their own unique advantages over wireless door magnets. Wired door magnets transmit door and window status information to the main controller via a wire, which is more stable and reliable than wired door magnets. As wired door magnets are connected by wires, they are not affected by signal interference and there is no need to worry about signal loss or interference. At the same time, wired door magnets can be integrated with other security devices, such as alarm systems and surveillance systems.

Magnetic switches: what they are and how they work Have you ever thought that many devices in our daily life use magnetic switches? For example, our refrigerators, washing machines, televisions and so on. So, what is a magnetic switch? How does it work? Let's find out together. A magnetic switch, also known as a door magnetic switch, is a device that uses magnetic materials and electrical principles to achieve the switching function. It usually consists of a magnet made of magnetic material and an electromagnet wound with a coil. When the magnetic switch is in the closed state, attraction occurs between the magnet and the electromagnet, causing the circuit to close and current to flow; while when the magnetic switch is in the open state, the magnetic force between the magnet and the electromagnet disappears, the circuit breaks, and current stops flowing. So how does a magnetic switch work? Let's explain it through a concrete example. Suppose you have a door magnetic switch installed in your room. When you open the door, the magnetic switch senses the state of the door and transmits the signal to the relevant equipment, such as light or air conditioner. When you close the door, the magnetic switch also senses it and passes the signal to the devices, causing them to stop working. In this way, we can achieve intelligent control through magnetic switches. The working principle of door magnetic switch
