The BIRNS Millennium 3X is an excellent Class A connector for large applications, available with almost any combination of contacts. The 3X can be supplied for high-voltage, high-current, and/or electromechanical use (to 3 tons).

An electromechanical 3X with 186 conductors (130:22, 3:20, 52:16, 1:10) was used on the Pioneer robot sent into Chernobyl nuclear power station (left).

A 40A/2.5kV 3X with 38 conductors (4:20, 12:16, 22:8) was used on a high-voltage, high-power towed military device, on steel-armored electromechanical tow cable.
