Waterproof Prewired Connector for Rock Drill Rigs This prewired connector is engineered to establish secure electrical connections in rock drill rig control systems, facilitating signal and power transmission in harsh mining environments. Its integrated wiring and rugged design eliminate on-site termination errors, reducing installation time while ensuring reliable performance in dusty, wet, or high-vibration conditions.
Key Performance Attributes
Durability & Protection:
IP67-rated housing (polyamide PA66) withstands dust ingress and temporary water immersion (1m for 30 minutes), validated to IEC 60529 standards. The UV-resistant material prevents degradation in outdoor applications, maintaining integrity after 2000+ hours of sunlight exposure .
Tinned copper conductors (0.75mm²) resist corrosion, ensuring stable conductivity over time. Silicone seals at the interface and cable entry prevent moisture intrusion, critical for underground or rain-exposed rigs .
Electrical Reliability:
Rated for 250V AC/DC and 10A current, it safely handles power and signal lines in drill rig control circuits. Insulation resistance (≥100MΩ at 500V DC) minimizes leakage, complying with IEC 61984 safety standards .
The 7-pin configuration supports multiple signal paths, compatible with sensors, actuators, and control modules commonly used in rock drill rigs.
Operational Compatibility:
Designed for -40°C to +85°C operating temperatures, it performs in extreme cold (arctic mining) and high-heat (desert quarries). Vibration resistance (10-2000Hz) ensures connections remain intact during drill operation, meeting IEC 60068-2-6 requirements .
Plug-and-play design with 500+ mating cycles simplifies maintenance, reducing downtime during connector replacement.
Applications
Primary Use: Electrical connections in rock drill rig control panels, linking sensors, motors, and operator interfaces.
Mining Equipment: Compatible with surface and underground drill rigs requiring waterproof, vibration-resistant electrical connectors.
