Introduction to Corrosion resistant Magnetic Proximity Switch DMSG: A magnetic switch is a proximity sensor that responds to a permanent magnetic field (even through non ferrous metals). The operating distance is greater than that of an inductive sensor. The response curve is related to the direction of the permanent magnetic field< When a target (permanent magnet or external magnetic field) approaches, the magnetic conductivity of the coil core (the inductance L of the coil is determined by it) decreases, the inductance of the coil also decreases, and the Q value increases. Excite the oscillator to oscillate and increase the oscillation current< When a magnetic target approaches, the current consumption of the magnetic sensor increases accordingly. Technical parameters: 1. Technical indicators 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. Product features: 1. Long operating distance: a. Electromagnet with a large operating distance of 120mm; b. The permanent magnet has 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. Has strong resistance. 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. The structural characteristics and working principle of the corrosion-resistant magnetic proximity switch DMSG: 1. It is equipped with a dry reed tube and a piece of magnetic steel inside, which has the characteristics of melting point and wear resistance. 2. Sealing the reed tube and magnetic steel inside the shell can effectively prevent impact and has strong capabilities. 3. The magnetism of the small magnetic steel is insufficient to attract the springs inside the reed tube, and the switch remains in a normally open state. 4. When the magnetic steel approaches the switch from far to near in one direction, the spring contact inside the reed tube is attracted. When the magnetic steel leaves, the state of the reed tube is maintained because the magnetic steel inside the switch is magnetized at the same time. 5. When the magnetic steel approaches the switch again from the opposite direction, it is magnetized in the opposite direction, causing the magnetism to decrease, causing the reed spring to spring open due to elasticity, and the contact point to also disconnect. 6. Magnetic steel is directly installed on the detected moving object. When the magnetic steel passes back and forth through the switch, it drives the switch to work. Multiple detection point switches on the same movement trajectory only require one magnetic steel. Some products of Zhuoxin Company: DEDK5-32 belt slip controller
