PK1-A2Z-485-TH two-stage deviation switch product features ● Sturdy cast aluminum shell, electrostatic anti-corrosion coating suitable for installation in harsh industrial and mining environments ● Protection standard IP67 can also be used in harsh environments ● High performance micro switches and maintenance free copper tube technology are used for durability ● Rated speed of action rod bearings; 5000  RPM, suitable for belt speed; 6.35  Meters/second ● The inclination angle of the side rollers is 75 degrees, so when the conveyor belt deviates abnormally, the protection switch will also accurately act. PK1-A2Z-485-TH two-stage deviation switch Introduction: ● The two-stage deviation switch is a protective device used to detect the degree of conveyor belt deviation during operation, give an alarm, and automatically trigger an emergency stop. The use of a deviation switch can prevent damage to expensive conveyor belts and prevent further industrial accidents and personal injuries. The two-stage deviation switch can prevent it from being a protective device in safe operation of conveying systems. It is widely used in steel plants, thermal power plants, cement plants, chemical plants, ports, and so on. PK1-A2Z-485-TH two-stage deviation switch application range; ● Conventional belt conveyors, including flat belt conveyors and trough belt conveyors ● Underground and cableway supported belt conveyors ● Ship loading and unloading systems, stacker and reclaimer conveyors PK1-A2Z-485-TH, PK1-2B-1485-TH, PK1-2BW two-stage deviation switches PK1-A2Z-485-TH Technical specifications for two-stage deviation switches ● Contact capacity:; 2 SPDTs; 400VAC  10A ● Action angle: 20° ● Cable tension: 49± 10N  (5± 1kgf) ● Side roller tilt angle:≤ 75° ● Protection level: IP67 ● Environmental temperature: -20 ℃~+80 ℃ ● Cable inlet: M20× 1.5 ● Cable specifications: 6-12; mm   Thermocouple WREK-422 for power station temperature measurement, WREK-432, WREK-482, WREK-492WREK2-421, WREK2-431, WREK2-422, WREK2-432, WRNK-401, WRNK-421, WRNK-431,WRNK-481, WRNK-491, WRNK-402, WRNK-422, WRNK-432, WRNK-482, WRNK-492,WRNK2-421, WRNK2-431, WRNK2-422,.
