D38999 Nickel Aluminium Bronze Connectors

Apollo are pleased to offer the Marine Bronze NVS connector to complement the Souriau JVS and Amphenol TVS Nickel Aluminium Bronze ranges.

Derived from the MIL-DTL-38999 III and CECC 75 201.002 and thereby offering the same fit, form and function, these NVS Marine connectors offer commercial benefits. Apollo are offering build from stock or a 9-week lead time for non-stocked items.

Using a rugged and high corrosion resistant housing in Nickel Aluminium Bronze alloy, this design provides a high reliability connector with excellent saltwater corrosion resistance characteristics and dry mate sealing down to 4m immersion.

Contact arrangements with high density size 22D contacts giving up to 128 ways, through sizes 20, 16, 12 and 8. This permits a wide range of electrical power contacts to be used or high speed Databus or Optical contacts to be used in the standard connector. Contacts are terminated by crimping and are inserted and removed using standard plastic tools inserted from the rear of the connectors.
