Product Introduction:
Cross limit switch Xckmr54d1h29 is a commonly used small current master control. The control circuit is turned on or off by the contact action of the moving parts of the production machine. Usually, this kind of switch is used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse movement, variable speed movement or automatic reciprocating movement according to a certain position or stroke.
In the electrical control system, the cross limit switch Xckmr54d1h29 realizes sequence control, positioning control and position status detection. Used for stroke control and limit protection of mechanical equipment. Structure: Composed of operating head, contact system and housing.
Limit switches are widely used in various types of machine tools and lifting machinery to control the stroke of the equipment and perform terminal limit protection. In the elevator control circuit, the travel switch is also used to control the speed of the car door, the limit of automatic opening and closing, and the protection of the upper and lower limits of the car.
The structure controlled by the cross limit switch Xckmr54d1h29 also includes a casing, a rotating shaft and a control arm which is fixed on the rotating shaft extending out of the casing. It is a cross-shaped limit switch.; The first control cam, fixed on the rotating shaft, one side has a bulge; The second control wheel, fixed on the rotating shaft, one side has a groove; The third control wheel is fixed on the rotating shaft and has a groove around it; Positioning part, one end is fixed on the rotating shaft, the reset spring, one end is fixed in the shell, the other end is connected to the positioning part, the Components of travel switch respectively arranged on the control wheel, is provided with a control contact, corresponding to the corresponding to the convex or groove of the control wheel, the Components of travel switch respectively corresponds to the electrical control mechanism of the mobile device electrical connection, working, The external signal is transferred through the control arm to drive the rotating shaft to rotate, the control wheel on the rotating shaft according to the position of the groove in the control wheel corresponding to the control contact of the stroke switch element, sometimes connected, sometimes disconnected.
