Explosion proof two-stage deviation switch DQK2-15A-3B Explosion proof two-stage deviation switch DQK2-15A-3B Explosion proof two-stage deviation switch DQK2-15A-3B Technical parameters 1; Rated voltage: AC220-380V 2. Rated current: 1-15A (3A, 5A, 10A...) 3; Number of contacts: Two sets of independent normally open and normally closed contacts. 4. Housing protection level: DT type dustproof housing, protection level IP67. 5. Surrounding environment temperature: -25-80 ℃. 6. The switch can work under vibration conditions with a frequency of 10-60Hz and an amplitude of 0.75mm (10g). 7. Operating force: 5-7 kg. Working principle: When an emergency occurs on the conveyor belt, the steel wire rope attached to the swing arm can be pulled to rotate the swing arm and drive the internal cam of the motor to sense the micro switch, issuing a stop signal. Scope of application: Two level deviation switch for conventional belt conveyors: underground, cable support belt conveyors: ship loading and unloading systems; Stacking/reclaiming conveyor; Tilt and shuttle conveyors; Crane, excavator, boom limit: skirt feeder/conveyor: heavy-duty limit switch detects the deviation of the tape, which is a protective device for automatic alarm and shutdown of the tape machine control. Widely used in various belt conveyor equipment in fields such as metallurgy, coal, cement and building materials, mining, electricity, ports, metallurgy, chemical industry, etc& nbsp; Chemical explosion-proof thermal resistance, WRR-131, WRR2-131, WRN-230D, WRE-210D, WRN-430D, WRNK-431, WRK-240, WRK-520, WRS-132, WRT-620, WRN-130, WRN-130, WRNK-231, WREK-232, WRE-621A, WZPK-133S, WRN-631, WRE2-235T, WRER2-13, WRPB-230, WRE-621, WRN2-621,.
