KJT wiring cavity pull rope switch KJT-LSJ series is widely used in factories and mines with belt conveyors such as steel, cement, power plants, and mines. This product is installed on both sides of the belt conveyor and is used for emergency shutdown of the belt conveyor. This kind of protection switch pulls the wire rope at any point within the switch operating distance, cuts off the operating circuit, and shuts down the entire line to protect the safety of the tape machine and people.

When an emergency occurs at the tape transportation site, pulling the wire rope tied to the lifting eye is the action of the slider and switch in the machine, which sends a shutdown signal. The switch automatically resets after releasing the wire rope.

           

●The switch must be balanced and pressed on the fixed bracket of the rack;

●Tie the steel wire rope to the pull rings at both ends, and the rope on each side should not exceed 40m (it should be shortened when there is a slope);

●The pressure on the pull rope should be appropriate to ensure reliable reset of the switch;

●The drawstring is set parallel to the tape, and a lifting ring is added every 10m.

●The factory can purchase steel wire ropes according to the specifications required by users.

The address encoder uses a self-designed protocol to provide an RS485 communication interface to connect to the comprehensive protection instrument. By using shielded twisted pairs and communication repeaters, the transmission distance can reach 1km.
