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.

Applications for Magnetic Door Switches: Securing Your Home

Applications for Door Magnetic Switches: Securing Your Home Home security is very important to everyone. We all want to feel safe and secure in our homes. A magnetic door switch is a very effective device that can help us achieve this. In this article, we will look at the application of door magnetic switches and how it can keep your home safe. A door magnetic switch is an on/off device that is installed on doors and windows. It consists of two parts: one mounted on the door frame and the other on the door. When the door is closed, the two parts come together and trigger the switch, sending out a signal. When the door is opened, the two parts separate and the switch breaks the signal. This signal can be connected to your home's security system, such as an alarm system or surveillance system, to sound an alarm in the event of an unauthorised entry. Door magnetic switches have a wide range of applications. It can be used in homes, commercial premises, or anywhere security is required. In homes, door magnetic switches can be used on front doors, back doors, windows, etc. to help you monitor the security of your home in real time. When someone tries to enter illegally, the door magnetic switch will immediately trigger an alarm to scare away potential intruders and notify you or security personnel. In addition to securing your home, door magnetic switches can also be used in other scenarios. For example, access to shops or offices

Magnetic switches: what they are and how they work

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
