The HQJR-5cm-02KH magnetic switch 90-250VAC adopts the principle of magnetic induction to activate the internal switch, achieve the purpose of making and breaking contacts, and control the external circuit, overcoming the characteristics of poor contact and easy damage caused by mechanical collision switches. HQJR-5cm-02KH magnetic switch is also a type of proximity switch, which is made using electromagnetic working principle and technology, and is a position sensor. It can convert non electric or electromagnetic quantities into desired signals through changes in the position relationship between sensors and objects, thereby achieving the purpose of control or measurement. Magnetic proximity switches can achieve large detection distances with small switch volumes. It can detect magnetic objects (usually * magnets) and then generate trigger switch signal output. Due to the fact that magnetic fields can pass through many non-magnetic objects, this triggering process does not necessarily require the target object to be directly close to the sensing surface of the magnetic proximity switch. Instead, the magnetic field is transmitted to a long distance through a magnetic conductor (such as iron). For example, signals can be transmitted to the magnetic proximity switch through a warm place to generate a triggering action signal. This switch has strong capabilities and is suitable for use in areas without gas or coal dust hazards underground in coal mines. It is used as a deceleration point for shaft elevators, limit parking, over roll protection switch, loading and unloading gate, air door control and tunnel transportation, mine car counting, pusher, car stopper, and broadcasting station. It is also widely used as a speed switching circuit in automation control devices and relay protection devices in mining, machinery, light industry, metallurgy, chemical, textile, and scientific research departments. The shell of this switch and the shell of the control magnet are both made of brass (Hpb59-1) or stainless steel cast and processed. Small in size, light in weight, with anti impact strength, easy to install, use and maintain, dustproof and waterproof lamp features. The core adopts an epoxy resin sealing structure, which reduces the risk of electric arc and improves reliability. Magnetic switch means induction through a magnet, which is a magnet. There are several types of magnets available in the market, including rubber magnets, permanent magnet ferrite, sintered neodymium iron boron, etc. The switch is like a reed switch. Dry reed tube, also known as dry tongue reed tube, is a passive electronic switching element with contacts. It has a simple structure and small size, making it easy to control and other points. The outer shell is usually a sealed glass tube, which contains two elastic iron plates and is filled with a type of inert metal called rhodium. Normally, the two glass tubes made of materials are separate. When a magnetic substance approaches a glass tube, under the action of magnetic field lines, the two inside the tube are magnetized and attracted to each other, and they will be attracted together, connecting the circuit connected to the node. After the external magnetic force disappears, the two separate due to their own elasticity, and the circuit also disconnects. Therefore, as a circuit switching device controlled by magnetic field signals, reed switches can be used as sensors for counting, limiting, and so on (mainly used in the production of door and window magnets), and are also widely used in various communication devices. In practical applications, a * magnet is usually used to control the connection of these two metal plates, so it is also known as& lquo; Magnetron; rquo;。 Precautions for using magnetic switches
(1) Voltage and current should avoid exceeding the range of use
(2) It is strictly prohibited to directly connect the magnetic switch to the power supply and use it in series with the same load (such as relays)
(3) Before selecting and connecting the magnetic switch, it is necessary to confirm the working power source used. When using a DC power supply, the red wire of the magnetic switch should be connected to the positive pole of the power supply.
