MW2025 Series
Bore size 25.4mm, current 50A,100A
MW2025 slip rings
  • MW2025 series is large current rotary electrical connector,rotating electrical connector with bore 25.4mm.
  • The rotary electrical connector can be used for shaft installation or through gas-liquid catheter. This series slip ring can be with rated current 20A/30A/50A to over 100A.
  • The rotating electrical connector has the advantages of high precision rotation, stable performance and longer working life.
  • The contact material adopts metal + ultra hard gold-plated treatment, with small torque, long working life, small resistance ripples and stable transmission performance.
