Electric slip ring DHK010-16-002

through-borethrough-holefor industrial applications

Short description

• Compact through-hole slip ring for continuous 360° transmission of power and mixed signals.
• Model DHK010-16-002 with 10 mm inner bore and flange mounting option.
• Precious-metal multi-point brush contact; gold-plated rings and gold-plated alloy brushes.
• Support for mixed signal and power; configurable circuit count, current and voltage.

Series / Overview
The DHK mini inner-hole series supports custom and standard IDs from 3 to 500 mm and ODs 10 to 800 mm. The DHK010-16-002 combines a 10 mm through bore, mixed-signal/power transmission capability, a standard 2 A per ring option and up to 16 rings. Housing: aluminum alloy (engineering plastic or stainless steel optional). Designed for stable power and signal transmission in electromechanical systems requiring continuous rotation. Can be integrated with gas/liquid rotary joints or fiber-optic slip rings to form hybrid multifunctional solutions.
