Wattgate Connectors

Wattgate connectors are premium AC power connectors and receptacles widely used in high-end audio, video, and professional power cable applications. Designed with high-conductivity contacts, durable housings, and secure terminal systems, they are engineered to provide reliable electrical connections and minimize resistance. Wattgate's Audio Grade® connectors are especially popular among audiophiles and custom cable builders for use in amplifiers, power conditioners, source components, and home theater systems, where power delivery and connection quality are considered important factors in overall system performance.


Perma-Lock™ Terminals

The unique Perma-Lock™ terminals, as used on all WATTGATE™ IEC and wall connectors, work in the following way: As the terminal screw tightens down on the contact tang, it compresses the wire underneath the tang, causing the screw to exert an upwards lift of the collar overleaf. This lifting action “locks up” the threads on the screw. Stress-relieving of the terminals is virtually eliminated. Heat cycling and vibration cannot loosen the screw. To put it more simply, “as the screw goes down, the collar locks up.” Also eliminated is the need to tin the lead wires.

WATTGATE™ Three-Layer Plating Process

Featured on WATTGATE™ Audio Grade® connectors and receptacle. All contact elements share the following three-layer plating process:

1. Oxygen Free Copper plating – improves conductivity.

2. Electroless Nickel plating – necessary to prevent the leeching of the copper through the gold layer.

3. 24k Gold plating or Passivated Silver plating – improves conductivity and prevents corrosion.
