LX25-111B travel switch, a type of position switch (also known as limit switch), is a commonly used low-current master electrical appliance.?The collision of the moving parts of the production machinery is used to make the contacts move to realize the connection or disconnection of the control circuit to achieve certain control purposes.?Usually, this type of switch is used to limit the position or stroke of the mechanical movement, so that the moving machine automatically stops, moves in the opposite direction, moves at a variable speed or moves back and forth automatically according to a certain position or stroke.
Two: switch definition
1: LX25-111B travel switch In the electrical control system, the function of the position switch is to realize sequence control, positioning control and position status detection.?Used to control the stroke and limit protection of mechanical equipment.?Structure: Consists of operating head, contact system and housing.
2: In the actual production of LX25-111B travel switch, the travel switch is installed in a pre-arranged position. When the module installed on the moving part of the production machinery hits the travel switch, the contact of the travel switch will act to switch the circuit.?Therefore, the travel switch is an electrical appliance that switches the circuit according to the travel position of the moving part, and its function principle is similar to that of a button.
3: LX25-111B travel switch is widely used in all kinds of machine tools and hoisting machinery to control its travel and carry out terminal limit protection.?In the elevator control circuit, the travel switch is also used to control the speed of opening and closing the car door, the limit of automatic door opening and closing, and the upper and lower limit protection of the car.
4: LX25-111B travel switch can be installed on relatively stationary objects (such as fixed frames, door frames, etc., referred to as still life) or moving objects (such as driving vehicles, doors, etc., referred to as animals).?When the animal approaches the still life, the connecting rod of the switch drives the contact of the switch to cause the closed contact to break or the open contact to close.?The action of the circuit and mechanism is controlled by the change of the open and closed state of the switch contact.
Three: type characteristics
1. Imported travel switch:
The LX25-111B travel switch series is the most representative. This type of product has fine workmanship, superior performance, and performance in extreme environments. It has won a large number of fans, but the high price has also made many users speechless.
2. High temperature resistant travel switch:
LX25-111B travel switch series high temperature resistant travel switches are generally used in steel mills.?The limit switch can work normally in a high temperature environment. The maximum operating temperature is 350 degrees. The life of the product will be reduced if the temperature of the working environment increases. If the temperature exceeds 300 degrees, the workload of the switch should be reduced to ensure the life of the product.?This series of travel switches has low price and stable performance, which has won unanimous praise from customers.
3. Waterproof travel switch:
The LX25-111B travel switch series is more prominent.?The travel switch has the characteristics of small size, high sensitivity, strong sealing, oil resistance and corrosion resistance. The most amazing thing is that this type of travel switch can work in water, which is beyond the dust of similar products.
