Mercotac Model 205 Rotary Electrical Connector
Mercotac Model 205 - 2-Conductor Precision Rotary Connector
The **Mercotac Model 205** is a compact, high-reliability rotary connector featuring a 2-conductor configuration rated for **4A per channel**. By employing a liquid metal conductive medium instead of mechanical brushes, the 205 achieves a "noiseless" electrical path with a contact resistance of **less than 1mΩ**. Designed for high-speed operation up to **2000 RPM**, this unit is exceptionally durable, maintenance-free, and ideal for transferring sensitive thermocouple, strain gauge, or video signals in demanding rotating environments.
Product Highlights
- Brushless Technology: Maintenance-free liquid metal contact system
- Ultra-Long Life: Rated for over 1 billion rotations
- Signal Purity: Negligible electrical parasites for noiseless transmission
- High Frequency: Supports data and RF signals up to 200 MHz
- Compact & Light: Optimized for space-constrained industrial assemblies
- Made in USA: High-precision manufacturing and material quality
Primary Applications
- Sensitive Sensor and Transducer Feedback

Installation & Operational Notes
To ensure the extreme longevity and performance of the Mercotac 205, please observe the following:
- • Mounting Orientation: Liquid metal connectors must be mounted within a specific orientation to maintain fluid contact (typically within 45° of vertical).
- • Handling: The housing is anodized aluminum; avoid high-impact loads during assembly to protect internal seals.
⚠️ SAFETY NOTICE: Mercotac connectors contain mercury. They must be disposed of according to hazardous waste regulations and should never be used in food processing equipment.
