This product is installed on both sides of the belt conveyor and is used for belt conveyor emergencies. A protective switch for shutting down. Pull the wire rope at any point within the operating distance of the switch to cut off the operating circuit and shut down the entire line to protect the safety of the tape machine and people.

●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.
