EDAC Rack and Panel Connectors

Rack and panel connectors, also known as rectangular connectors, are ideal for applications with many wires in a backplane or where very high continuity signals are required.

What is a rack and panel connector?

EDAC Rack and panel plug and receptacle connectors are available in 14, 20, 36, 38, 56, 90 and 120 pin sizes. The Edacon hermaphroditic contacts, with four contact mating surfaces, have 10 micro inches of gold plating. Terminations include crimp, PC Tail, wire hole, and wire wrap. The following image shows a plug and receptacle rack and panel connector.

EDAC’s hermaphroditic contact design

The following image shows a cross section of EDAC’s hermaphroditic contact design with its forked blades. The contacts align in the male and female insulators at 90 degrees to one another. When mated together they provide four points of contact, creating a gas tight connection. Very high quality, high continuity connections.

The contacts have chamfered or beveled edges that float in the insulator. With the large number of connections and to compensate for stacked tolerances, this float allows for some movement of the contacts, to help in the ease of mating.

Rack & panel hoods and back shells

Optional covers are available with side or top cable entry, and include the strain relief. The plastic covers provide dust and debris protection while the metal covers provide this, along with EMI protection. The versatile metal cover has a removable side panel to help facilitate the ease in inspection and replacement of wiring in the field. The following image shows EDAC’s metal cover with EMI protection.

Accessories and tools

Contacts and covers are available separately or can be combined with the connector as one part number. Actuating screws or locknuts, and polarizing hardware come standard. Polarizing pins and sockets can be adjusted in the field to 288 different mating combinations.

Hand crimp tools, or presses and applicators for automated production of your cable assemblies, are available. Addition tools for contact installation, or extraction, and for changing the polarizing hardware, are also available.


The primary markets are broadcast, automotive, transportation, telecommunications, and energy. Each of the following is an example of a benefit of using a rack & panel connector.


Audio patch bays must deliver clean, high quality signals. It is imperative that there’s no poor-quality signals as it could cost a company a loss in advertising revenue.


Automotive test panels are very important, and poor-quality signals could affect the readability of the vehicles’ systems causing a company to send out a defective car. Improving the signal quality by using a rectangular connector will ensure better readability.


Oil and gas refineries need a very reliable, high continuity connection for the safety of their employees, and the systems they operate. Systems with pressure transducers and temperature sensors feed through data loggers that connect back to computers. The rack and panel connectors ensure those are pure signals; increasing the accuracy of the results.

The rack and panel connector is best suited for industries/customers that require a high continuity, highly reliable connection, with very high shock and vibration resistance. MIL-C-28731 available.

EDAC directly crosses to AVX Elco 8016 and 8017 connector family.
