TCK-3T mine shaft magnetic switch magnetic switch TCK magnetic switch has achieved good technical indicators and performance due to the comprehensive use of a series of design and process technologies, and can be applied in various coal mines. Can work reliably in the mine shaft without maintenance. The TCK series magnetic switch is a non mechanical contact magnetic proximity switch. It is composed of magnetic sensors, electronic circuits, and output switches. When the permanent magnet of the magnetic detection body enters the induction area of the TCK magnetic switch magnetic sensor, the magnetic switch will rely on the action of the magnetic field and the TCK switch to output a switch signal. The output signal reflects the position and movement direction of the detection body, and this signal can be used as a travel control signal for the control system.

What are you still hesitating about? If you are interested in a certain product, hurry up with the company to consult or order it! There are two types of TCK series magnetic switches: universal type and type (universal type with aluminum casing, type with copper casing and stainless steel casing), and four types of products: TCK-1 magnetic switch, also known as single point magnetic switch. TCK-2 magnetic switch, also known as two-point magnetic switch. TCK-3 and TCK-4 retaining magnetic switches& The TCK-1 proximity magnetic switch (single point magnetic switch) operates for 2 seconds when an external S-pole magnetic field acts on the magnetic sensor. When stationary, the switch is in a transition state, and when the magnetic field is lost, the switch will automatically reset. Similar to general mechanical instantaneous action button switches, it switches when pressed and automatically resets when released& The TCK-2 magnetic switch (two-point magnetic switch) can recognize the direction of magnetic field movement. When the magnetic sensor detects that the external magnetic field in the N-S pole direction has crossed zero, the switch operates and switches for 2 seconds. When stationary and about to cross zero, it is in a transition state. When it loses the effect of the external magnetic field, it automatically resets. The S-N pole direction magnetic field does not convert when crossing zero. The TCK-3 and TCK-4 magnetic switches are retention type magnetic switches, and their magnetic field forms are different. The TCK-3 type magnetic proximity switch has two states that can be maintained. When the external S-pole magnetic field acts on the magnetic sensor from bottom to top, the switch switching contact is connected to the upper end. At this time, the indicator red light will be on, and this state is maintained. Even if the external magnetic field is lost, the switch is powered on or powered off, it can still maintain this state. When an S-pole magnetic field acts on the magnetic sensor from top to bottom, the switching contact is connected to the lower end. At this time, the green indicator light will light up and remain in this state until the next bottom-up action. The S-pole magnetic field acts up and down on the TCK-3 magnetic induction switch. The magnetic switch can not only switch actions, but also maintain various states, similar to the mechanical button switch that is moved up and down with force. When the TCK-4 type magnetic proximity switch detects an external magnetic field (N-S pole direction magnetic field) crossing zero, the switch's switching contact is connected to the upper end. At this time, the indicator red light will be on, and this state is maintained. When the external magnetic field (S-N pole direction magnetic field) crosses zero, the switch switch switch contact is connected to the lower end. At this time, the green indicator light will light up and remain in this state. The TCK-4 type retention type magnetic proximity switch has a very accurate narrow window hole magnetic field zero crossing conversion characteristic and a high positioning degree. The TCK magnetic switch uses sensitive and reliable magnetic sensors and microelectronic devices, with high resolution, high magnetic sensitivity, and a wide response frequency. The circuit design adopts redundant structure and technology, and adopts a switching power supply with a power supply voltage of 50-60Hz AC85-265V. All circuits are cured with epoxy resin inside cast aluminum or cast copper switch housings, fully sealedSo it can be waterproof and resistant to impact. Due to the comprehensive use of a series of design and process technologies, TCK magnetic switches have achieved high technical indicators and performance, and can be applied in various coal mines. Can work reliably in the mine shaft without maintenance. There are two methods to use TCK magnetic switches on single rope and multi rope hoists in mines: permanent magnet magnetic field source method and steel wire rope magnetic field source method. Both of these uses can directly detect the actual position of the lifting container. Both methods can be used simultaneously to achieve dual protection. Combined with electrical control equipment, it can ensure the accurate operation of the hoist. The application of TCK-3T in mining machinery: Our company's TCK-T magnetic switch has been widely used in mining machinery and other industries, and has received praise from users. The TCK series magnetic switch * can be used for wellbore switches. The TCK-T type magnetic switch uses sensitive and reliable magnetic sensors and microelectronic devices, with some magnetic sensitivity, high resolution, and wide response frequency. The circuit design adopts redundant structure and technology, and adopts a switching power supply with a power supply voltage of 50-60Hz 85-265VAC. All circuits are cured with epoxy resin inside cast aluminum or cast copper switch shells, fully sealed, waterproof, and resistant to impact. Due to the comprehensive use of a series of design and process technologies, TCK magnetic switches have achieved high technical indicators and performance, and are suitable for various mines. There are five main performance indicators for magnetic induction switches: the connecting cables used: check whether the wires inside the connecting wires are copper or tin plated. Tin plated wires have much better performance than copper wires and may be more expensive (10 core cables). Generally, in order to save costs, cheaper copper core wires are used. Reaction of magnetic switch to magnet: When the magnetic induction switch is used in combination with TS250 magnet, the large distance between the magnet and the magnetic switch is 245mm~255mm. Products larger than 260mm and smaller than 240mm are not qualified products. Product appearance: The appearance should be designed to be beautiful, clean, and the surface of the sealed gel should be flat and shiny. 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 interval between the magnet and the magnetic switch should be (120mm, 220mm). The influence of geomagnetism on the magnetic switch: a good magnetic switch should have good ability, and an important indicator for judgment is the influence of geomagnetism on the magnetic switch. The testing method is as follows: using the TS250 magnet as an example, point the head of the magnetic switch towards the geographical south and geographical north respectively, and then align the S pole of the TS250 magnet with the head of the magnetic switch for testing; In both cases, the large 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 will be around 5mm. If the interval is greater than 15mm under the influence of geomagnetism, then it is not a qualified good product.
