What are SOCAPEX Connectors?

SOCAPEX Connectors are power connectors which are used in the entertainment industry amongst others.

They consist of 19 Pin electrical connectors, heavily used in Film, Television and stage lighting, where there is a need to terminate the ends of a multicable 

The original SOCAPEX cable is made by Amphenol, but the term is now used to describe the particular type of connector generically.

The connectors are wired with six live pins, six neutral and six earth pins with a final central pin which helps align the male and female connectors.

Syntax SSX 19 Pin SOCAPEX Connectors

The Syntax SSX 19 Pin SOCAPEX Connectors have been built to enable the most stable coupling and the fastest wiring possible.

When you buy Syntax SSX SOCAPEX Connectors you are getting safer, better looking, and practically indestructible connectors that are redefining quality in the entertainment industry.


100% Socapex 419 series compatible.

UL Compliant

SOCAPEX SSX 19-pin connector

Panel and inline versions

The SYNTAX® SSX SOCAPEX series are designed for professional lighting applications and totally compatible with standard Socapex 419 series.

The connectors are extremely robust, made of thick wall construction machined aluminium alloy, with hard-wearing black painted or anodized finish.

The thermoplastic insulating insert enables the use of removable contacts, either crimp or solder.

The unit is completely IP67 watertight when mated.

Electrical safety and compliance are guaranteed by internal insulation of the shells, obtained through a safety insulating sleeve preventing electric shock, as well as “first make last break” ground contacts.

Grounding rings allow bussing of the ground contacts. Locking rings and backshells are designed for easy handling.


Anti-rotation design

Cutting edge high-precision machined anti-rotation shell design

Syntax SOCAPEX connectors feature a proprietary anti-rotational design which prevents the insulating insert from spinning within the shell.

Featuring four large keys and four smaller keys on the insert, the keys are also physically displaced from one another and are interlocked with as many keys on the metal housing.

This ant-rotational system ensures that the connector's interior is positively locked, putting an end to a long-standing industry problem.

The Syntax anti-rotation device was first designed in 2011 and has been implemented in the production of SSX connectors since 2012.

The latest cutting edge design has been available since 2018.

Inserts are available in the following colours;: black /standard), redblueyelloworange.


For other color options, please contact our sales department.


Colored locking rings

The rubber-coated version of the locking ring is now available also on the SSX 19 pin SOCAPEX and 16 pin connectors series. For quick identification of your cables through colour coding, four different colors are available: black (standard), red, blue, yellow.

For other color options, please contact our sales department.

Below the rubber coat, the connectors feature a proprietary heavy-duty metal ring, that has achieved worldwide appreciation and has set a new standard in the industry for both strength and durability.

The unique design of the locking-ring ensures an optimal grip on the whole circumference and ensures easy coupling.

The design of the thick wall inner metal ring provides unparalleled resistance to all possible forms of abuse.

The connectors locking rings represent an evolution of the rubber-coated rings commonly found on the market and solve the problem of their being mechanically weaker compared to all-metal construction rings.

Available colors on request: Blue - Red - Gold - Green - Purple - Silver (Photo 3 and 4)

Rounded edge female contacts

A benchmark set on mechanical perfection
The latest design of the Syntax SOCAPEX SSX female contacts feature a rounded shape of the contact entry ports which allows smooth contact insertion inside the insulating insert providing a seamless mating with no damage on the pin cavities and positive contact placement and retention.

Faster and safer contact insertion
The rounded edge female contacts are supplied as a standard on all SSX SOCAPEX female connectors. This proprietary Syntax design eliminates the need to use lubricants or guide pins to insert the contacts, greatly reducing assembling time.

Armored contacts


An innovation of the SOCAPEX SSX series
The Syntax armored contacts are available on request on all-female versions (inline and panel) Syntax SSX 19 pin SOCAPEX and 16 pin connectors.

The armored contacts are provided with a protective jacket to improve contactation on SSX connector.

The usage of armored contacts results in a series of mechanical and electrical advantages.

  • self-centered for a seamless connection
  • increased number of mating cycles
  • improved electrical conductivity
  • lower operating temperature
