Pull cord switch is the sensing element to detect the deviation of the belt conveyor, it can sent out the signal according to the condition of the level of deviation. What’s more, it not only can realize automatic alarm and shutdown, but also can prevent the damage and deviation of belt conveyor. When the conveyor belt is deviation, the belt will drive one side and make the side deviation. At the end, it will touch the pull cord switch, the alarm signal will be given out. The belt conveyor will stop to work if the belt continue to deviate and touch the other set of contact. When there are emergency incident of the conveyor belt equipment, you can pull the wirerope at any position along the site. The wire rope pulls the drive arm to rotate 30 degrees to the self-locking position, the torsion spring in the junction box keeps the precise CAM structure in position, Precision cam-driven micro switch to cut off the control line,When resetting, it is necessary to manually press down the reset handle to make the torsion spring spring up, and the driving handle can be restored to the normal state. When the micro switch sends the stop signal, the red action indicator will be raised. In addition, micro switch can be installed to increase the application range.
The features of the pull cord switch:
1.You can drive the pull cord switch at any position along the site and the sensitive action.
2.Manual reset mode.
3.Easy to install, installed in the conveyor belt terminal or between the two ends.
4.Cast aluminum case with good air tightness and ip-67 weather resistance.
5.When the pull rod rotates 30 degrees, the stop switch signal can be output.
