Mining sealed magnetic switch KEJ-2X0.1.220 I. Introduction: It has the characteristics of no collision and strong ability. Mainly used for detecting the position of moving objects. When the magnetic steel on the moving object passes through, the output contact of the proximity switch closes, and when it leaves, the contact opens. Widely used in places with explosive hazards such as coal mines, chemicals, and petroleum, it is an ideal sensor in modern automatic control systems. 2、 The working principle adopts the principle of magnetic induction, which is amplified by electronic power to achieve on/off control of external circuits. Used in conjunction with KY35 series control magnets. The switch is fixedly installed in the position that needs to be controlled, and the magnetic steel is directly installed on the outside of the controlled moving object. When the magnetic steel passes back and forth through the switch, it drives the switch to work. 3、 Technical parameter 1, technical index a) Close to the rated voltage of the switch: AC36V~260V; DC36V~260V; b) Proximity switch contact method: normally open; c) Large relative speed between proximity switch and magnetic steel: 15m/s; d) The effective operating distance between the switch and the magnetic steel depends on the size of the magnetic steel. The maximum operating distance is 150mm2, and the environmental conditions and precautions for use are as follows: a) The ambient temperature is -5 ℃ to+60 ℃; b) Atmospheric pressure: 80KPa~106KPa; c) Relative humidity:≤ 95%（+25℃）； d) Atmospheric pressure: 80KPa~106KPa; e) In situations where there is no significant vibration or impact; f) In situations where there is explosive mixture underground in coal mines, but there is no corrosive damage to insulation. g) Sealing products are strictly prohibited from being knocked or modified during operation to affect their explosion-proof performance. 4、 Product feature 1: Long operating distance: a. Electromagnet * Large operating distance 120mm; b. Permanent magnet with a large operating distance of 150mm. 2. Strong load carrying capacity: can directly carry 3A (effective value) load, and add intermediate relay transition. anquan、 Reliable and convenient. 3. Sensitivity, reaction speed: Response time less than 2.5ms. 4. Can work in extremely harsh environments: a. Adaptable to a wide temperature range: -50 ℃& +120 ℃ b. Strong:. c. Waterproof and dustproof. 5. As long as there is no strong magnetic field near the switch and it is installed according to the requirements of the product technical manual, it can ensure that there is no false operation of the switch 500000 times and the reliability is 100. 6. The working characteristics of the magnetic proximity switch: it is a non-contact switch that relies on magnetic induction to fundamentally solve the problem of misoperation caused by contact. 7. Application scope: Mainly used in coke oven equipment, dump truck equipment, and other steel equipment. Mining sealed magnetic switch KEJ-2X0.1.220 magnetic switch refers to the induction through a magnet, which is a magnet. There are several types of magnets, including rubber magnets, permanent magnet ferrite, sintered neodymium iron boron, etc. commonly used in the market. 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 the advantages of simple structure, small size, and easy control. The outer shell is usually a sealed glass tube, which contains two iron elastic plates and an inert material called rhodium. Usually, the two pieces made of special materials in the glass tube are separated. When a magnetic substance approaches a glass tube, under the action of magnetic field lines, the two pieces inside the tube are magnetized and attracted to each other, attracting them together and 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 that uses magnetic field signals to control, reed switches can be used as sensors for counting, limiting, and so on (mainly used in the production of door magnets and window magnets in security systems), and are also widely used in various communication equipment. In practical applications, magnets are usually used to control the connection of these two metal plates, so they are also known as "; Magnetron;.
