TCK-4 Encapsulated Mining Magnetic Proximity Switch Manual TCK series magnetic switches have two types of universal and four types of products: TCK-1 magnetic switch; TCK-2 magnetic switch; TCK-3 and TCK-4 Holding Magnetic Switch TCK-4 Casting Magnetic Proximity Switch Manual TCK series magnetic switches are non mechanical contact magnetic proximity 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 TCK switch magnetic sensor, relying on the magnetic field, the TCK switch operates and outputs a switch signal. The output signal reflects the position and movement direction of the detection body, and serves as a stroke control signal for the control system. TCK-4 type holding magnetic switch. When the magnetic sensor detects a zero crossing of the N-S pole direction magnetic field in the external magnetic field, the switch's switching contact is connected to the upper end, and the indicator red light is on. This state is maintained. When the magnetic field in the S-N direction of the external magnetic field passes zero, the switch switching contact is connected to the lower end, indicating a green light and maintaining this state. The TCK-4 magnetic switch has accurate narrow window hole magnetic field zero crossing conversion characteristics and positioning accuracy. They use sensitive and reliable magnetic sensors and microelectronic devices, some of which have high magnetic sensitivity, resolution, wide response frequency, and positional accuracy. 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 two methods to use TCK magnetic switches on single rope and multi rope hoists in mines without maintenance: permanent magnet magnetic field source method and wire rope magnetic field source method. Both of these uses directly detect the actual position of the lifting container. Both methods can be used simultaneously, combined with electrical control equipment, to ensure accurate operation of the hoist.
