Product Description
Mercotac Model 331 Rotary Electrical Connector
Mercotac Model 331 - 3-Conductor 30A High-Speed Connector
The **Mercotac Model 331** is a specialized 3-channel rotary connector optimized for heavy-duty industrial power and signal transmission. Supporting **30A per conductor**, this unit features a brushless liquid metal path that ensures a "noiseless" electrical bridge with a contact resistance of **less than 1mΩ**. Designed for high-speed stability up to **1800 RPM**, it provides exceptional reliability for multi-phase power or sensitive data transfer, maintaining signal integrity for frequencies up to **100 MHz** throughout its lifespan.
Product Highlights
- 3-Channel Versatility: Triple conductors rated for 30A each
- Brushless Technology: Zero-wear liquid metal contacts for extreme longevity
- Ultra-Low Noise: Superior signal integrity for sensitive instrumentation
- High-Speed Support: Consistent performance rated up to 1800 RPM
- Maintenance Free: No brushes to replace; eliminates carbon dust build-up
- High Frequency: Suitable for data and RF signals up to 100 MHz

Operational & Safety Guidelines
- • Mounting Orientation: Liquid metal connectors must be mounted within 45° of a vertical axis for fluid integrity.
- • Mechanical Loading: Use flexible leads to avoid mechanical stress on the housing terminals.
- • Housing Note: The anodized aluminum body is electrically "hot" to one of the internal conductors.
⚠️ HAZARDOUS MATERIAL: This product contains mercury. Do not use in food or pharmaceutical processing. Dispose of in accordance with environmental regulations.
