metalstainless steelcompact

Product Overview
This integrated electrical and fiber optic slip ring assembly, model DHS025-19-1F, is a high-performance rotary interface designed for reliable power, signal, and optical data transmission in demanding 360° continuous rotation applications. It combines 19 electrical channels and 1 single-mode fiber optic channel in a compact, durable stainless steel housing.

Core Advantages

• Integrated Design: Combines high-current electrical paths with a low-loss optical channel in one compact unit, simplifying system design.
• High Reliability: Features precious metal contacts, robust stainless steel construction, and a long service life (≥3M revolutions) for mission-critical applications.
• Stable Performance: Low and consistent insertion loss for the optical channel, minimal contact resistance variation, and excellent insulation ensure signal integrity.
• Built for Harsh Environments: Operates reliably across a wide temperature range and is protected against dust and light moisture (IP51).

This slip ring assembly is the optimal solution for advanced rotary systems where performance, durability, and data fidelity cannot be compromised.
