Mundorf Binding Post Connector TPCU750E Pure Copper EVO

Mundorf TPCU750E MConnect TPCU Series Compact Pure Copper Binding Post

The Mundorf TPCU750E was specifically engineered for audio applications with thinner wall thicknesses, such as compact power amplifiers and speaker terminal plates. Made in Germany from solid Oxygen-Free Copper (OFC), it pairs a lean 20 mm body diameter with versatile connectivity, including a cross-hole that accommodates bare wire or a second banana plug.

Featuring an unplated pure copper finish, the TPCU750E offers low transfer resistance and natural, uncoloured acoustic performance for high-end audio systems.

Key Features & Applications:

• Designed for Thin Wall Panels: Compact profile optimised for amplifier chassis and speaker terminals with low wall thicknesses.
• Solid OFC Copper Construction: Precision-crafted from 99.99% pure oxygen-free copper for maximum current delivery.
• Expanded Connectivity: Built-in cross-hole accepts bare wire ends, large spade lugs, or a second 4 mm banana plug.
• Anti-Rotation Insulation: Includes keyed insulating hardware for rotation protection and clear polarity marking.

Installation & Mounting Tips:

• Non-Metallic Mounting Plates: Use non-metallic mounting boards (e.g. acrylic, wood, or resin) as recommended by Mundorf to avoid power and detail loss from counter-rotating magnetic fields.
• Panel Notch Drilling: Drill the main chassis hole along with the 2 mm anti-rotation key notch as detailed in the technical drawing.
• Internal Wiring: Solder internal hookup wire directly to the rear solder tab or attach via 6 mm spade connectors.
