Technical specifications
- DHK series mini through-hole slip rings for transmitting signals, low/high currents and voltages through a central bore
- Designed to allow passage of pipes, cables, fluids or rotating shafts while maintaining electrical continuity
- Precious-metal multi-point brush contact for low friction and stable electrical connection
- Through-hole (bore) diameter: 8 mm (model DHK008-5)
- Gold-plated rings with gold-plated alloy brushes; supports mixed signal and power transmission
- Fully customizable (circuit count, current, voltage, housing material, lead length); no standard stock
Product Detail
- Series: DHK mini inner-hole (through-hole) slip rings
- Standard ID: 3–500 mm; OD: 10–800 mm (custom sizes available)
- Model DHK008-5: 8 mm bore for rotating electromechanical systems requiring a through passage
- Example configuration: 8 rings; typical per-ring rating examples: 2 A (configurable)
- Standard housing: aluminum alloy; optional engineering plastics or stainless steel
- Can be integrated with fiber-optic, liquid, or pneumatic rotary unions to form hybrid solutions
Typical Applications
- Winding machines and rotating drives
- Laser scanners and imaging systems
- In-pipe inspection cameras and borehole equipment
- Exhibition and display rotating mounts
- Vending and food dispensing machines
- CCD inspection systems and machine vision
- Automated assembly and rotary indexing machines
- Rotating LED lighting, labeling and marking equipment
- Laboratory instruments and biological testing devices
- Any application requiring 360° electrical/power/signal transmission through a central bore
Product Naming Description
- DH = electric slip ring series
- K = through-hole installation (inner bore)
- Numeric value indicates through-hole bore diameter (example: 008 = 8 mm)
- Suffix indicates total circuits (e.g., -5) and additional ID numbers may denote cable length, connector type or installation variant
- Rated current can be specified per circuit when heterogeneous circuits are used
