The working principle of the HFKLT2-2 explosion-proof two-stage deviation switch is to pull the steel wire rope attached to the hanging ear at any position along the conveyor belt in case of an emergency on site, forcing the internal cam to rotate and driving the microcomputer switch to act, issuing a shutdown signal, achieving the shutdown effect and preventing the expansion of the accident& nbsp; Environmental conditions for use a. Environmental temperature: -40 ℃~60 ℃; b. Relative humidity not exceeding 85%; c. The sea level does not exceed 2000m; d. Service life: 100000 switch actions; e. Insulation voltage: AC1000 test for 1 minute HFKL2-2 Jiehang bidirectional pull rope switch is mainly used in conveying systems in industries such as metallurgy, power, coal and rock, mining, and chemical engineering. It is a sensing element for conveyor automation control. This product is a protective device for emergency shutdown of tape conveyors on site. This product is made of high-quality aluminum ingot alloy precision die-casting and uses imported travel switches. It has the advantages of high strength, light weight, good sealing, and long product service life. This product is internally certified by the National Institute of Electrical Safety Supervision and Inspection (NEPSI) for explosion-proof instruments and meets the GB12476.1-1990 standard; The specified requirements& nbsp; Shenzhen Shengli High Temperature Meter: VC203, VC-203，VC306A,VC-306A,DM6801A,DM-6801A,DM6902,DM-6902,VC305A,VC-305A; Shenzhen Shengli High Frequency Meter: VC3165, VC-3165，VC3218A,VC-3218A; Shenzhen Shengli High Temperature and Humidity Meter: VC330, VC-330; Shenzhen Shengli High Megaohmmeter: VC60D+, VC-60D+,VC60B+,VC60D,VC-60D; Shenzhen Shengli High Capacity Meter: VC60E, VC-60E，VC6013C，VC-6013C，VC6013B,VC-6013B, Shenzhen Shengli High Clamp Watch: VC6016A, VC-6016A,VC6016C,VC-6016C,VC6056A，VC-6056A，VC6056B,VC-6056B,DM3218,VC6018A,VC-6018A,VC6056D,VC-6056D,VC6226，VC-6226; Shenzhen Shengli High Multimeter: VC6056C, VC-6056C,VC830L,VC-830L, VC3021,VC9205，VC-9205，VC9208，VC-9208，VC3010，VC70F,VC-70F；  Shenzhen Shengli High Bench Multimeter: VC8045-II, VC-8045-II,VC8045II,VC8145B,VC-8145B,VC8155，VC-8155，VC8145A,VC-8145; Shenzhen Shengli High Phase Sequence Table: VC850, VC-850，VC850A,VC-850A； Shenzhen Shengli High Multimeter: VC98A, VC-98A,VC98C,VC-98C； Shenzhen Shengli High Grounding Resistance Meter: VC4105A, VC-4105A,VC4105B,VC-4105B； Shenzhen Shengli High Clamp Watch: DM6015F, DM-6015F，DM6019，DM-6019，DM6050+,DM6050+,DM6050+，DM-6050+，DM6052+，DM-6052+； Shenzhen Shengli High Tachometer: DM6234P+, DM-6235P+,DM6235P,DM-6235P,DM6236P,DM6236P; Shenzhen Shengli University Verification Instrument: VC01, VC-01，VC02，VC-02，VC03，VC-03，VC04，VC-04，VC05，VC-05，VC11，VC-11，VC14，VC-14，VC15，VC-15，VC15+,VC-15+,VC140，VC-140，VC1713B，VC-1713B，VC1715B,VC1715B,VC25，VC-25， Shenzhen Shengli High Network Test Table: VC468, VC-468; Shenzhen Shengli High Vibration Tester: VC63, VC-63, VC63A, VC-63A; Shenzhen Shengli High Clamp Grounding Surface: VC6412, VC-6412; VC189，VC-189，VC-187，VC187，VC469，VC-469; Shenzhen Shengli High Process Multimeter: VC78, VC-78，VC79，VC-79; Shenzhen Shengli High Anemometer: VC816, VC-824, Shenzhen Shengli High Noise Meter: VC824, VC-824, Shenzhen Shengli High Distance Meter: VC851, VC-851，VC851A,VC-851A, Shenzhen Shengli High Coating Thickness Tester: VC852A, LT202 Theodolite/LT-202; LT202L Theodolite/LT-202L; YB9150 Multifunctional Instrument/YB-9150; DZJ-2 vertical aligner/DZJ2; YB9170 Multifunctional Instrument/YB-9170; CY2674B Pressure and Leakage Tester/CY2674B; TPS407 Total Station/TPS-407; TPS802 Total Station/TPS-802; CY2674E Leakage Current Tester/CY2674E; TPS805 Total Station/TPS-805; CY2674G Leakage Current Tester; TPS806 Total Station/TPS-806; TPS807 Total Station/TPS-807; SPINTER 100/100M/Level/SPRINTER-100/100M/; SPRINTER200/200M | Level/SPRINTER200/200M; NA720 level/NA-720; YB2670B withstand voltage tester/YB-2670B; NA724 level/NA-724; YB2670C withstand voltage tester/YB-2670C; NA728 Level NA-728; YB2670D withstand voltage tester YB-2670D; CY2666A withstand voltage tester; NA730 level/NA-730; Guangzhou Yitai Technology Grounding Resistance Instrument: ETCR2000, ETCR-2000，ETCR2000B,ETCR2000B; Guangzhou Yitai Technology Digital Phase Meter: ETCR4000, ETCR-4000; Guangzhou Yitai Technology Clamp Meter: ETCR9000, ETCR-9000，ETCR5000，ETCR-5000，ETCR5000A,ETCR-5000A;
