Like the BCR, this is a mounted receptacle. It is more expensive since it is machined from a larger block of stainless steel. It is also more difficult to mount since it requires five holes instead of one. However, it is ideal for use with the right angle plug since keyway orientation can be controlled. It is possible to get this receptacle with an extra O-Ring seal mounted on the F surface for an additional piston type seal (available by special order).
Burton® 5500 Series connectors have no O-Ring seal between the plug and receptacle. Our seal is a face-type seal integrally molded as part of the plug and cannot fall off. Stub acme threads are used on the 16-size and larger shells.
Stub acme threads are difficult to cross thread or damage. The electrical contacts have crimp connections to the conductor; not solder joints. Crimp contacts have superior flex life compared to soldered joints.
All elastomer to metal bonding surfaces are sandblasted, cleaned, and primed. Then units are molded under several thousand pounds of pressure for 20 minutes at high temperature. This assures a complete bond which prevents water migration.
