Socapex 19 Pin Cable & Connectors Complete Guide
It is not uncommon for multiple stage lights running power to create a tangle of individual raw cables. Each line has to be routed, labelled, inspected and removed — all of which takes time.
The solution to this issue is achieved through a Socapex 19 pin system that carries several lighting circuits in one multicore cable. Often employed in concerts, theatre performances, movie studios & film sets, touring productions as well as temporary event installations.
It may appear to be a simple system on the surface, but connector type, wiring, cable size, circuit rating and breakout design all count. Wrong assembly choice can cause compatibility issues, broken contacts, or unsecure power distribution.
In this how-to guide, we explore what a Socapex system is and what the buyers and production crews should look for before putting one into service.
Related Article: What Is a Socapex 19 Pin Connector?
A Socapex connector is a round multipin power connector that groups multiple electrical circuits into one connection.
The 19-pin style that is usually associated with stage and entertainment lighting, The technology enables crews to substitute six individual cable runs for one Socapex cable (also called a Soca cable by lighting ops).
A typical system includes:
- Potentially a power distribution or dimmer source
- A break-in assembly
- A multicore Socapex extension cable
- A Socapex breakout
- Fewer connectors for lighting fixtures
Typically has its special round locking connector The ring helps make sure the two halves are aligned together correctly, while preventing an accidental disengagement.
They are available in cable and panel-mounted versions. Also consider that a “male/female” format is being used, but connector gender does not mean direction of power delivery. According to the assembly marks and wiring plan, crews need to comply with the documentation of your equipment.
Is it Six Circuits in One Socapex 19 Pin?
A typical six circuit wire arrangement uses these three contacts for each circuit:
- One line or hot conductor
- One neutral conductor
- A single protective earth or ground conductor
This means that 18 active contacts are required for six circuits. In a common six circuits pinout although, pin 19 is left electricall
This configuration keeps the two different circuits electrically isolated. The neutrals and grounds are typically not common between the six circuits.
When checking a pinout do not be fooled by connector appearance. Older equipment, bespoke assemblies (built by hand), motor-control systems and other locally-sourced products may be wired in a different way.
Before a conditioned production inventory, every cable must be tested and marked with its purpose.
The Purpose of Socapex Cable, Break-In and Breakout
Socapex equipment also comes with its set of jargon, and it can become confusing when two similar looking assemblies provides opposite duties.
Socapex Extension Cable
A Socapex cable is essentially a multicore cable that runs between two 19 pin connectors. Holds all six circuits in a single outside jacket.
The varied length and any number of conductors can be manufactured for extension cables. The right selection is reliant upon demand, cable length, voltage drop, ambient condition and complete assembly rating.
There should be strain relief for the cable at both ends. Roy says that without it, a repeated pull and flex can stress the internal terminations.
Socapex Break-In
A break-in takes six power feeds and combines them into a single multipin connection.
Depending on the connector types used, these individual tails can employ stage pin, Edison, CEE, PowerCON-type, twist-lock or bare-end terminations. The specific type of connector format varies with power distribution equipment and by region.
The break-in is usually located near the power supply. Individually each tail must suit the intended circuit and protection device.
Socapex Breakout
This is opposed to the job of a Socapex 19 Pin breakout, which is basically doing this in reverse. This is divided up into six independent outputs at the lighting fixtures and pulls apart the six circuits from the multicore line.
Breakouts can be obtained as fan-out cable assemblies or packaged boxes. Fan-outs are lightweight and quick to position on a truss, breakout boxes a fixed set of outlets and often better physical protection.
Clear circuit labels are valuable. This assists technicians to locate faults, balance loads, and connect fixtures without needing to trace every tail back to the distribution point.
Where Is Socapex Commonly Used?
Socapex systems are applicable if multiple lighting circuits need to follow the same route.
Common applications include:
- Concert and festival lighting
- Theatre lighting bars
- Television studios
- Film production sets
- Touring dimmer racks
- Exhibition and event lighting
- Temporary truss systems
So, a crew needs six controlled circuits on an overhead truss. They will have fewer cables to deal with; rather than lifting six long power cables, they can run one Soca cable and put a breakout near the fixtures.
It reduces cable volume and might mean easier setup and teardown. It does not eliminate the need for planning circuit, computing load calculations, overcurrent protection and electric testing.
Things to Consider Before Buying Socapex Assemblies
We do not have the same electrical or environmental rating across every 19-pin product. Ratings can vary from one connector brand, cable type, contact size or completed assembly to another.
Many connector families that mate with Socapex 19 Pin refer to ratings like 25 amps at 500 volts AC, along with IP67-rated protection while mated. All such figures relate to the product family as named, not automatically all Socapex together on Socapex 19 Pin.
Check the Complete Assembly Rating
The practical limit is set by the weakest link. An excellent connector does not make up for small conductors, inappropriate tail connectors, underwhelming terminations or lousy strain relief.
Review:
- Current rating per circuit
- Voltage rating
- Conductor size
- Cable length
- Connector compatibility
- Indoor or outdoor suitability
- Temperature range
- Ingress protection
- Termination method
- Local electrical requirements

Inspection and Handling Tips
Touring work often plugs and unplugs a Socapex connection several times, so inspection becomes routine.
Before plugging, inspect the pins and sockets for dust, bending/heat marks/corrosion/looseness. The coupling ring must be free and give a firm hold upon connection.
Never force two connectors together. When they cant with light, controlled pressure, stop and check alignment, keying and condition of contacts.
Store them with protective caps fitted. Coil the cable, using a twist-free and bend-free method like this: Never break away an assembly by pulling on the cable jacket.
Regular checkups for electrical tests must be done at the right intervals as well after repairs. A qualified person should verify wiring, insulation, continuity, and ground paths with appropriate test equipment.
Readers may reference figure 1 for a TMB six-circuit connector pinout but the absolute rule is to always compare any diagram against documentation for the exact product being used.
Conclusion
Socapex 19 pin system is a useful multicore that allows you to carry six independent lighting circuits through one multicone. The key parts of it are the Socapex connector, extension cable, break-in and breakout assembly Yes.
It is possible for the system to alleviate cable congestion and improve production work — but only if every piece of equipment has been properly rated, wired, inspected, and matched according to the application.
Prior to selling or placing into service a Socapex cable, verify that the pinout, conductor size, connector format, electrical rating and environmental conditions are as required. Documentation and clearly labeled circuits are as important as the hardware itself.
