The 1804 Series of ruggedized 4-pin, connectors have been used in applications ranging from military vehicle electric reactive armor to airborne Synthetic Aperture Radar. The 1807 has even been used on the Ion Propulsion systems that have propelled some of NASA’s most successful spacecraft into Deep Space.

1804 uses connector housings which come in, shielded and non-shielded configurations with either threaded or bayonet coupling nuts. Plug kits are available for customer-fabricated cable assemblies using Teledyne Reynold's specified wire.
