PROFIBUS slip ring DHK007

electricRS-485RS-422

Short Description

• DHK007 series custom through-hole conductive slip rings for small-bore rotary applications.
• Designed for a through-hole bore of 7 mm (suitable for bores ≤ 7 mm).
• Advanced precious-metal multi-point brush contact ensuring reliable electrical contact and low friction.
• Custom-made product — no standard stock.
• Gold-plated rings with gold-plated alloy brushes.
• Supports combined transmission of signals and power.
• Customizable number of circuits, current rating and voltage per project.

Product Detail
The DHK007-58-3A mini through-hole conductive slip ring features a 7 mm bore, 58 circuits and a rated current of 3 A per circuit. It is intended for compact rotating electromechanical systems where the installation requires a central bore smaller than or equal to 7 mm. The standard housing is aluminum alloy; special engineering plastics or stainless steel are available on request.
For continuous 360° transmission of power and signals, the DHK007 series can be integrated with rotary unions, liquid rotary adapters, fiber-optic rotary joints and other modules to create multifunctional hybrid rotary interfaces.

Typical Applications

• Machine vision and intelligent robotics
• Packaging machines
• Filling and dosing equipment
• Cutting and machining systems
