Key Applications
Ideal for high-speed signal transmission in demanding industrial environments:
- Aerospace: Aircraft engine testing (strain gauge & thermocouple signals)
- Rail Transit: High-speed rail component validation (350+ km/h simulations)
- Automotive: Wheel hub performance testing (torque & temperature monitoring)
- Industrial Robotics: Rotational joints in precision machinery
Technical Advantages
- Gold-Gold Contact Technology: 99.99% pure gold plating (≥5μm thickness) provides 200% longer lifespan than silver-graphite contacts
- Precision Concentricity: Integrated casting ensures ≤0.01mm concentricity between ring grooves and bearings
- Mirror Surface Finish: Contact surface roughness reaches Ra0.02 (optical mirror quality), reducing friction loss by 40%
- Ultra-Precision Machining: Dimensional tolerances <0.01mm (ISO 2768 H grade) with 5-axis CNC processing for thermal stability
- Near-Zero Pressure Brush Design: Extends service life by 33% through reduced mechanical wear with self-lubricating PTFE composite brushes
- Rugged 304 Stainless Steel Housing: IP65-rated sealing resists dust, moisture, and corrosion in -50°C to 80°C environments
Physical Dimensions
- Diameter: 25.4mm
- Lead Wires: 400mm standard (custom lengths available)
- Mounting Holes: 4-M2.5 threaded holes (16±0.1mm pitch)
Factory Validation
