for medical equipmentfor the lighting industrystainless steel

Short Description
Ingiant specializes in medical-grade capsule slip rings. The DHS020-12-2A features 3 circuits with 8 A rated current per circuit, IP51 protection, and a stainless steel housing, designed specifically for smooth 360° rotation of surgical lights to ensure reliable power transmission in operating rooms.

Core Advantages for Medical Environments

• Medical grade reliability: Precision-engineered with precious-metal contacts and silver-plated Teflon wires (Φ1.8 mm AWG17), ensuring ultra-low contact resistance fluctuation (≤0.03 Ω) and no signal interference for flicker-free surgical illumination.
• Optimized for surgical light arms: Compact outer diameter (Φ20 ±0.1 mm) and total length 33.1 mm. Lead wires customizable (Rotor: 900 ±5 mm / Stator: 300 ±5 mm) for integration into articulated lamp arms.
• Robust and safe construction: Stainless steel housing with IP51 protection resists dust and moisture, operates from -20 °C to +65 °C and supports up to 200 RPM for continuous smooth rotation.
• Electrical safety and compliance: Withstand voltage 500 V @ 50 Hz and insulation resistance ≥500 MΩ @ 50 Hz to meet medical equipment safety requirements.
