SUBSEA 5500 SERIES CIRCULAR CONNECTOR
The 5500 Series is an extremely rugged and reliable underwater electrical connector. It is the standard Cooper Interconnect connector series with pins in the receptacles and sockets in the plugs.
The pin and socket relationship is due to the fact that in most applications, power runs from the plug into the receptacle.
For safety reasons, it is desirable never to have power available on the pin side. For reverse power applications, refer to Cooper Interconnect's 6600 Series.
For over 3 decades the Cooper Interconnect 5500 Series has been the industry standard connector for applications which require
reliable service in severe situations. The rugged metal shells, recessed pins, and face-type seals assure dependable service in the most demanding situations.

5500 SERIES CONNECTOR CONFIGURATIONS
Please refer to the illustrations below. The receptacles (which have pin contacts) are shown on the left. The
plugs (which have socket contacts) are shown on the right. This is the standard arrangement as power normally flows
from the plug into the socket. For safety reasons, the possibility of live power on pins should not be allowed. If the
reverse contact arrangement is required, please refer to the Cooper Interconnect's 6600 Series.
The descriptions below correspond to the illustrations below. The part number refers to the first 4 digits of the part number.
BCR Bulkhead Connector Recepticle (5507)
Less expensive than the FCR, this is the standard receptacle mount. It may be used with any plugs. When using
the BCR with a right angle plug (CCP-RA), a BCR retaining ring must be used instead of tapped threads. This is
due to keyway orientation.
FCR Flange Connector Receptacle (5506)
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 5 holes instead of 1. 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).
CCR Cable Connector Receptacle (5502)
An in-line receptacle mounted on a cable. It can be used as part of a cable splice unit or other specialized application.
CCR-AT, Attachable (55A2)
Used in the same applications as the CCP except that it is designed to be attached to its cable by the customer.
CCP Cable Connector Plug (5501)
The standard plug for most applications. Like all of the plugs, it mates to any of the receptacles. This plug is molded
to cable at the Cooper Interconnect factory.
CCR-RA Cable Connector Plug, Right Angle (55R1)
This plug should be used when the cable must exit the receptacle at a 90 degree angle. Normally, the FCR is recommended
for use with the right angle plug to assure keyway orientation.
CCP-AT Cable Connector Plug, Attachable (55A1)
Used in the same applications as the CCP except that it is designed to be attached to its cable by the customer. A
variation of this plug is available as a PBOF (pressure balanced oil filled) assembly. The connector shell is modified
to accept a new backshell which has an oil fill port and a hose attachment. Please consult the factory for details.
5500 Series Dimensions
5500 Contact Patterns The contact patterns shown below are available for any connector type with the Cooper Interconnect 5500 Series. Cooper Interconnect is constantly adding new items. Please register your catalog to receive automatic updates.
Some contact patterns are available with larger sized conductors. For example, the 3210 and 3212 are available with
up to 12 AWG conductors.
For high voltage contact patterns, please see the high voltage section.
5500 Series High Voltage Connectors
A number of 5500 Series contact patterns are available with higher voltage ratings (standard rating is 600v). Ratings
of 1000v, 2000v, and 3000v are available. Due to certain 5500 Series High Voltage Connectors design constraints and material limitations, not all patterns are available in all voltage ratings.
Cooper Interconnect 5500 Series high voltage connectors differ from the standard rated units in several areas. There is a contact
shoulder which increases the surface track distance between contacts. Different insulation materials may also be used.
All Cooper Interconnect high voltage connectors are built to be equally rugged and reliable as the standard voltage rated items.
The following contact patterns are available. Cooper Interconnect is continuously adding products, please contact the factory
for availability of other patterns.
5500 Pressure Balanced Oil Filled (PBOF)
The 5500 plugs are also available in PBOF form factor. oil fill port. .
The plug is a modified 55A1 attachable designed to accommodate a special backshell which has a hose barb and oil fill port. The part number becomes 55P1-XXXX-0000.
For special extreme applications, a JIC type fitting is available on the backshell. This makes it possible to use a hydraulic
hose instead of clear tubing.
PBOF connectors may be ordered separately or made up as cable assemblies. Due to the difficulty of shipping cable with oil, we leave that to the customer.
5500 Series Accessories
A number of accessories are available for the 5500 Series. Some are shown on below. Please contact the factory for specific requests.
