Large-Bore Explosion-Proof Slip Ring (220mm Inner Diameter, 20 Channels, 10A)

• Non-Standard Large-Bore Explosion-Proof Slip Ring-DHK large inner hole Series

Available for custom, standard ID 3-500 mm, OD 10-800 mm

DHK220F-20-10A series Large-Bore Explosion-Proof Slip Ring (220mm Inner Diameter, 20 Channels, 10A).Certified to China’s GB3836 explosion-proof standard, this slip ring combines intrinsically safe circuitry with a flameproof steel housing for dual spark-leakage prevention. Its sealed design blocks dust/gas intrusion, with an IP65 rating ensuring harsh-condition performance. Crafted from 304 stainless steel and paired with 3rd-gen precious metal fiber brush contacts, it delivers lossless power/signal transmission. Supporting up to 300rpm rotation, its dynamic resistance stays ≤5mΩ, ensuring stable high-current/high-frequency data flow. A modular design allows customizable multi-channel media configuration, while its robust build withstands extreme environments (high temp, humidity, corrosion). Tailored for filling machines, reactor mixers, AGV explosion-proof vehicles—safe and reliable.

• Typical Applications:

• ​Filling Machines: Ensures continuous rotation without power interruption, preventing production bottlenecks.
• ​Reactor Agitators: Provides reliable power for mixing volatile substances in chemical reactors.
• ​AGV Explosion-Proof Vehicles: Enables safe navigation and data transmission in warehouses or factories with flammable materials

• Product Naming Description:

(1)Product type: DH—electric slip ring
(2)Installation method: K—through hole
(3)Through hole product bore diameter 220 mm   F—Explosion-Proof
(4)Total circuits:20 circuits
(5)The rated current or it will not be marked if it passes through a different rated current for the circuits.

(6) Identify number: –XXX; In order to distinguish different specifications of the same product model, the identification number is added after the name. For example: DHK080-24 has two sets of products with the same name, the cable length, connector, installation method, etc. are different, you can add the identification number: DHK080-24-002; if there are more of this model in the future, and so on -003 , -004, etc.
