JK18-125 AC Limit Switch

JK18-125 AC Limit Switch is a mechanical position control device which specifically is designed for industrial automated system,its core function is to realize the automated power off protection or running direction change of the device by testing the travel limit of mechanical moving parts accurately.The switch is mainly suitable for AC 50Hz(60Hz),rated operational voltage to 380V(440V),rated operational current for 125A construction elevator power supply circuit.When the limit switch loses its function,the limit stop block is used to push the joystick,so that the moving contacts and the static contacts of the three pairs of contacts inside the switch are separated,and the total power supply of the elevator is cut off to achieve the terminal limit protection of the elevator.

Product Description

The switch uses a highly sensitive silver alloy contact structure, with excellent arc and wear resistance. Double break contact design with quick action mechanism, can quickly complete the breaking action, to ensure that in the mechanical overdrive fast cut off the circuit. The built-in powerful reset spring system ensures that the switch can maintain a stable contact pressure under frequent start-stop conditions, especially for cranes, machine tools, automated production lines and other industrial scenarios requiring accurate stroke control.

As a key component of the electrical mechanical interlock protection system, the JK18-125 achieves multi-functional adaptability through modular structural design. The swing lever drive mechanism can be configured with different actuating parts such as roller and fork arm, which supports horizontal and vertical multi-directional installation. The built-in bidirectional action mechanism can not only realize the free combination of normally open and normally closed contacts, but also set the bidirectional stroke protection by adjusting the position of the ram.
