1, using environmental conditions
  a Ambient temperature -30~+50oC
  b Relative temperature is not more than 85

2, the main parameters are shown in the table below

parameter model	Angle of action	Limit angle	Operating force (kg)	Number of contacts		Contact rating	Reset mode	reliability	Weight (KG)
				Normally open	Normally closed
KLT2-I type	30o	60o	10	1	1	AC380V	automatic	>10 sixth power	3
KLT2-II type	30o	60o	10	1	1		Manual		3.5

Fourth, structural characteristics
1. This machine adopts aluminum alloy precision die-casting shell, high strength and light weight;
2, the enclosure has a large IP65 protection level and can work in harsh environments;
3, the machine uses the inlet to form the switch, the contact capacity is large, the action is sensitive, reliable, and the structure is shown in Figure 1.
Five, working principle
When an emergency occurs on the belt conveyor, the wire rope attached to the swing arm can be pulled, the swing arm rotates, and the inner cam is driven to close the drive stroke switch, and a stop signal occurs.
After the fault is removed, the limit lever can be pushed to reset.
Six, installation adjustment
This machine is generally installed on the racks on both sides of the belt conveyor;
1. Fix the rope switch to the bracket and then solder it to the frame;
2, the distance between the two machines is 25-30m, and the wire rope with the diameter of φ4 is connected, and the tightness should be moderate;
3, in order to influence the self-weight of the small wire rope on the start of the switch, weld a bracket on the frame every 3m, a support wire rope;
4, the user can make the installation bracket, or order it from our factory.
Seven, wiring method
The machine is equipped with a 3-core rubber cable at the factory, and the cable is equipped with a wire number. Refer to Figure 3 for wiring.
Eight, the user must know
Users can order the support ring, adjusting bolt or purchasing wire rope made by our factory.
Nine: in line with national implementation standards: GB12476.1-1990

The two-way rope switch is widely used in steel, cement, power plants, mines and other factories with belt conveyors. This product is installed on both sides of the belt conveyor. It is a protection switch for emergency shutdown of the belt conveyor. Pull the wire rope at any point within the operating distance, cut off the running circuit to stop the whole line, and realize the protection of the belt conveyor and personal safety. When an emergency occurs at the tape transportation site, pulling the steel wire rope attached to the lifting lug is the role of the slider and switch in the machine to send a stop signal. 
   This product has self-locking protection. It can be reset by pressing the limit lever after the accident is eliminated. It has a long service life. It has good sealing performance and has the advantages of dustproof, shockproof and anticorrosive.
