Technical parameters of TCK-2 TCK-3 magnetic induction wellbore switch 1. Power supply voltage: AC85-265VAC2, contact current:/250V3, number of contacts: 2 sets of normally open and 2 sets of normally closed 4. Response speed: 30m/s 5, working frequency: more than 100000 times 6. Waterproof, seismic resistant and rust resistant TCK-2 TCK-3 magnetic induction switch Sensor parameters TCK series magnetic switches have two types: universal and type, and four types of products: TCK-1 magnetic switch; TCK-2 magnetic switch; TCK-3 and TCK-4 retaining magnetic switches& TCK-2 TCK-3 magnetic induction wellbore switch parameters (1) TCK-1 magnetic switch TCK-1 magnetic switch, when the external S-pole magnetic field acts on the magnetic sensor, the switch operates and switches for 2 seconds. When in a stationary state, it is in a transition state, loses the magnetic field effect, and automatically resets. Similar to general mechanical instantaneous action button switches, press to switch and release to automatically reset. (2) TCK-2 magnetic switch TCK-2 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 the zero crossing point is stationary, it is in a transition state and loses the effect of the external magnetic field, automatically resetting. The S-N pole direction magnetic field does not convert when crossing zero. (3) The TCK-3 and TCK-4 holding magnetic switches have different magnetic field forms. The TCK-3 type holding magnetic switch has two states that can be held. 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, and the indicator red light is on, which is maintained. Even if the external magnetic field is lost, the switch is powered on or powered off, it still maintains 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, indicating a green light, and it remains in this state until the next bottom-up action. The S-pole magnetic field acts up and down on a type 3 magnetic switch, which can switch and maintain various states, similar to using force to move a mechanical button switch up and down. 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. This explanation mainly introduces these two usage methods.
