Product Description
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.

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.
