Key features and benefits

Description

The 8NA6G is a connector with cable field plug and is the latest addition to the 8NA range. It can easily be implemented for signal connections and can be connected to equipment mounted with 8NA receptacles.

The 8NA6G cabled field plug is dedicated connector complying with LOCA safety requirements for the nuclear energy industry. Thanks to robust stainless steel shells and high sealing performances, 8NA6G connectors are designed to operate during normal, accident and post-accident conditions.

Esterline Connection Technologies - SOURIAU has supplied more than one hundred nuclear reactors in service worldwide with 8NA products.
