AMPHENOL Australia has released power connectors designed to provide safe and dependable power interconnects in portable equipment of any type, especially in demanding applications. The Neptune connectors are suitable for land or offshore oil exploration equipment, modular power generation equipment, modular manufacturing plants and convention centre power distribution.

The range includes plugs and receptacles from 30A to 400A at 600V, with Amphenol's Radsok contact system allowing more amperage and voltage through a smaller connector. The lightweight, rugged aluminum hardware is machined from high-tensile strength bar stock and finished with a hard coating to 40 points on the Rockwell C scale. Conductors are readily terminated to easily accessible pressure wire terminals.

Cable housings, with ample wiring space, slip over the conductors after termination, eliminating cumbersome handling and seating of inserts with conductors attached.

Armoured and sheathed cable built to IEEE-45/UL1309, IEC, BS, DIN, and JIC standards are compatible with the Neptune connectors, as are unarmoured cables and flexible cables, including S, SO, SOOW-A, W, and G-GC type cables.

The contact inserts are interchangeable and reversible to suit specific needs. The contacts are made from copper with standard silver plating and are available with optional gold plating. The new connectors are rated IP-68-8 and feature a dielectric strength of 1,800V.

Radsok uses the tensile strength properties of the flat, high-conductivity alloy grid for the high normal forces required for conductivity, while providing a large conductive surface area. This results in a correspondingly low voltage drop and low temperature rise while maintaining low insertion forces. Radsok sizes used in Neptune are #12, #10, #4, #1/0, #4/0, and #350 MCM.
