Mercotac Model 1250 Rotary Electrical Connector
Mercotac Model 1250 - Heavy-Duty 250A Rotary Connector
The **Mercotac Model 1250 series** is designed for high-power industrial applications where traditional brush-type slip rings fail due to heat or wear. With a rated current of **250A** and a contact resistance of **less than 1mΩ**, the 1250 ensures high-efficiency power transfer with minimal voltage drop. This single-channel connector is ideal for high-current welding, plating, and large-scale rotating platforms, offering maintenance-free performance at speeds up to **1200 RPM** and frequencies up to **200 MHz**.
Product Highlights
- Massive Power Capacity: Rated for a continuous load of 250A
- Liquid Metal Technology: Ensures a constant, low-resistance electrical path
- Near-Zero Noise: Superior signal integrity even in high-power environments
- Maintenance Free: No brushes to replace; designed for high-duty cycles
- Versatile Mounting: Options for metric threads and stainless steel housings
- Thermal Range: Operational stability from -20°C to +60°C
Primary Applications
- Large-Scale Industrial Welding Equipment
- Electroplating and Surface Treatment Units
- High-Current Rotary Tables & Turntables
- Heavy-Duty Cable Reels and Drum Systems
- Packaging and Laminating Machinery
- Sensitive Data Transfer in High-Power Systems

Series Designators & Operational Notes
- • "SS" Designator: Indicates stainless steel ball bearing (recommended for high humidity).
- • "M" Designator: Indicates metric thread (M10 x 1.5) for simplified international mounting.
- • "MS" Designator: Combines metric thread with stainless steel ball bearings.
- • "SX" Designator: Indicates both stainless steel body and bearings for maximum corrosion resistance.
- • "MSX" Designator: Comprehensive metric, stainless body, and stainless bearing configuration.
⚠️ INSTALLATION WARNING: Ensure high-current terminals are securely fastened to prevent localized heating. Mercury-based connectors must be mounted in the proper orientation for fluid integrity.
