The KGE-1AP casting type magnetic induction switch for mining use is a non mechanical contact magnetic proximity switch in the Shandong Zhuoxin wellbore switch mining TCK and KGE series magnetic switches. It consists of magnetic sensors, electronic circuits, and output switches. When the permanent magnet of the magnetic detection body enters the induction area of the switch magnetic sensor, the switch operates and outputs a switch signal through the action of the magnetic field. The output signal reflects the position and movement direction of the detection body, and serves as a stroke control signal for the control system. This product uses weak magnetic sensors and microelectronic devices, with some magnetic sensitivity, high resolution, and wide response frequency. The circuit design adopts technology. There are two types of outputs: AC solid-state switch (AC SSR) and electromagnetic relay (EMR) contact. The output switch has a large capacity. The system design adopts reliable technology. Each function is equipped with two sets of circuits, connected in parallel. As long as two circuits with different functions fail simultaneously, the switch can operate normally. Features of KGE-1AP Casting Magnetic Induction Switch for Mining: 1. It adopts gate pulse magnetic compression technology, which is energy-saving and stable, with a power consumption of 30 milliwatts. 2. Using circuit technology to reduce false alarms and false alarms in signals. 3. By adopting * technology, the magnetic switch can operate reliably over a wide detection range. 4. Strong product capability, good waterproof performance, temperature resistance, suitable for various complex environments. There are many types of magnetic switches available on the market, including KGE1, TCK, TK, etc. There are also a few, but there are very few qualified magnetic switches on the market now. There are two types of TCK series magnetic switches:
One is unipolar: magnetic switches have an effect on the S pole of the magnet and no effect on the N pole, and this type of magnetic switch has strong capabilities; At the same time, unipolar magnetic switches can affect the magnetic switch after cage magnetization, which cannot be achieved by bipolar magnetic switches. This type of magnetic switch is more effective< The second type is bipolar: magnetic switches have an effect on both the S and N poles of the magnet. However, for the case where the cage is magnetized, bipolar magnetic switches cannot be used well, often causing inaccurate alignment, signal errors, and making it difficult for users to use. This type of magnetic switch is relatively expensive< In general, unipolar magnetic switches are widely used on site due to their strong capabilities, while bipolar magnetic switches are less commonly used because they are easily affected by cage magnetization. There are five indicators to judge the performance of magnetic switches: 1. Appearance of the product: the appearance should be designed to be beautiful, clean, and the surface of the sealed colloid should be flat and shiny< br/>2、 Using connecting cables: Check whether the wires inside the cables are copper or tin plated. Tin plated wires have much better performance than copper wires and are also more expensive (10 core cables). Generally, cheap copper core wires are used to save costs< br/>3、 Reaction of magnetic switch to magnet: When the magnetic switch is used in combination with TS250 magnet, the interaction between the magnet and the magnetic switch is 245mm~255mm. Products larger than 260mm and smaller than 240mm are not qualified< br/>4、 The influence of geomagnetism on magnetic switches: A good magnetic switch needs to have good capabilities, and one of the main indicators for judgment is the influence of geomagnetism on magnetic switches. 5. Unipolar magnetic switches have a positioning window of *. The establishment of a positioning window can significantly improve the positioning of the magnetic switch on the cage. The discrimination method for positioning window: When a magnet approaches the magnetic switch from far to near, the distance between the magnet and the magnetic switch is represented by L when L> At 255mm, the magnetic switch does not operate, and at 100mm< l<255mm， The magnetic switch is in the active state when l< 100mm magnetic switch in non operating state; This can control the installation position on site and improve the positioning of the magnetic switch. So when installing a magnetic switch, the distance between the magnet and the magnetic switch should be (120mm, 220mm). Magnetic switch performance parameters:
1. Power supply voltage: AC 85-265v< br/>2、 Contact parameters: 127v 2A< br/>3、 Number of contacts: Two sets of normally open and normally closed points< br/>4、 Speed response: can meet the speed requirement of 30M/S< br/>5、 Working frequency: The mechanical life of the contacts can reach 00 times< Our company's mines upgrade corresponding accessories. Our company's TCK and KGE series magnetic switches are mainly used in mine shafts as cage positioning signals and lifting degree indicators. Widely used, it can detect objects at distances of 250mm, 360mm, and 500mm when used in conjunction with corresponding magnets. The testing method is illustrated using the TS250 magnet as an example. The head of the magnetic switch is pointed to the south and north of the geography, and then the S-pole of the TS250 magnet is used to test the head of the quasi magnetic switch; In both cases, the distance between the magnetic switch and the TS250 magnet should be within the range of (245mm, 255mm), with an interval of 10mm. The shorter the interval, the smaller the influence of geomagnetism, and in good cases, the interval is around 5mm. If the interval is greater than 15mm under the influence of geomagnetism, it is not a qualified and good product. Note that the magnet mentioned in this article does not specifically refer to TS250 magnet
< 255mm, magnetic switch in active state, when l< 100mm magnetic switch in non operating state; This can control the installation position on site and improve the positioning of the magnetic switch. So when installing the magnetic switch, the distance between the magnet and the magnetic switch should be within (120mm, 220mm) series models KGE1-1P, KGE1-1T, KGE-1AP, TCK-1APTCK-1P, TCK-2P, TCK-3P, TCK-4PTCK-1, TCK-2, TCK-3, TCK-4TCK-1T, TCK-2T, TCK-3T, TCK-4T.
