Fiber optic slip ring DHK070-53

Ethernethydraulicpneumatic

Short Description
The DHK070-53 is a 53-circuit through-bore slip ring by Jiujiang Ingiant Technology Co., Ltd., featuring a 70 mm central bore. It enables continuous 360° rotation for mixed transmission of power and signals while allowing shafts, pipes or other components to pass through the central opening.

Core Specifications
Model definition: DHK = through-bore slip ring; 070 = 70 mm central bore diameter; 53 = 53 independent conductive circuits
Dimensions & weight: 70 mm inner bore; standard outer diameter 145 mm; length varies with circuit count; weight 7.15 kg; mounting: shaft or flange mounting

Electrical Parameters (customizable)

• Rated current (per circuit): selectable 2 A / 5 A / 10 A / 15 A / 20 A / 25 A
• Rated voltage: 380 VAC / 240 VDC
• Contact material: gold-gold multi-point fiber brush contact, low dynamic resistance fluctuation <10 mΩ, maintenance-free
• Insulation resistance: ≥1000 MΩ (500 VDC)
• Dielectric strength: 1500 VAC, 60 s, 2 mA

Environmental & Rotation Specifications
Operating temperature: -40 °C to +65 °C; Max humidity: <70%; Standard rotation speed: 1000 rpm; Protection: IP54 (upgradeable to IP65/IP67)

Transmission Capacity
Capable of mixed transmission of power, analog/digital signals and fieldbuses (CANbus / Profinet / Ethernet). Can be integrated with pneumatic, hydraulic and fiber-optic channels for composite transmission.
