High-Precision Slip Ring for High-Speed Rail & EMU Test Equipment

DHS030-9 Compact Slip Ring for High-Speed Rail & EMU Test Equipment

The DHS030-9 is a Ø30mm, 9-circuit precision capsule slip ring engineered specifically for high-speed rail (HSR) and EMU test rigs. With precious metal contacts, it delivers ultra-stable signal transmission with contact resistance variation < 10 mΩ, ensuring data accuracy from strain gauges, vibration sensors, and high-frequency transducers in high-vibration railway testing environments.

Key Features:

• 9 circuits, 2A rated current, compatible with 0~240V AC/DC
• Precious metal contacts​ for < 10 mΩ dynamic resistance fluctuation
• 30CrMo alloy steel housing​ — superior shock & vibration resistance
• Service life:​ 8,000~10,000 million revolutions
• IP51 protection, operating speed up to 300 rpm
• Operating range:​ -20°C ~ +80°C, < 70% RH
• Insulation resistance:​ ≥500 MΩ @ 500V DC; Dielectric strength: 500V AC, 60s
• Rotor side lead:​ 310±10 mm silver-plated AF-250-0.2mm² wire; Stator side: terminal blocks
• Flange mounting​ for easy integration into compact test benches
