In the entertainment industry, there are standards that seem almost immutable. The Socapex-style multipole connector is undoubtedly one of them: reliable, widespread, and practically ubiquitous in lighting and power distribution.
But requirements have evolved. Today, alongside power, more and more data is transmitted: lighting control, networking, digital audio, motor management. Continuing to handle everything with separate lines means increasing complexity, setup time, and the risk of errors.
It is precisely in this context that Link’s proposal fits in with the LKS series and, more recently, with LKS Data: a solution that starts from a well-established standard and brings it concretely into the future.
THE PRODUCT
The LKS range was introduced in 1997 as a more advanced evolution of traditional Socapex connectors. Over the years, it has maintained full compatibility while incorporating continuous, tangible improvements in terms of usability and safety.
The real leap, however, comes with LKS Data. The concept is as simple as it is effective: using the same form factor and logic of 19-pin connectors, but integrating a data transmission system within them. This makes it possible to manage both power distribution and control or audio signals through a single connection.
From an engineering standpoint, the solution is based on patented coaxial pins and an internal PCB that handles data via an RJ45 interface. All of this is achieved without sacrificing compatibility with standard Socapex cables, an essential factor for integration into existing setups.
The result is a hybrid system that drastically reduces the number of required lines, simplifying cabling and installations in increasingly complex environments.

"We have not yet had the opportunity to test the latest evolution of the series in a fully operational context, but previous versions have already proven their reliability and durability in the field over time. Even so, a hands-on inspection of the new series immediately gives a very positive impression. What stands out right away is the build quality: solid materials, precise workmanship, and an overall sense of a product designed to last. Every element - from the coupling ring to the cable locking system - conveys robustness and close attention to detail. It is also noteworthy how easily some solutions designed specifically for field work can be appreciated: the improved anti-rotation system, the possibility of replacing components without invasive procedures, and fast yet secure locking systems. In other words, this is not just innovation “on paper,” but a set of engineering choices that appear to stem from the real needs of professionals working daily with rigging, touring, and complex installations."
Conclusions
The LKS series already represents a concrete evolution of a long-established standard, improving its reliability in everyday use.
But with the new standard versions and LKS Data, Link takes a further step forward, introducing a decidedly more modern approach to distribution: fewer cables, greater integration, and improved efficiency.
In a sector where setup times, maintenance, and reliability make all the difference, the ability to combine power and data within a single infrastructure is not just a convenience, but a real operational advantage.
It is a solution clearly aligned with the needs of contemporary productions, and one that could become a new benchmark for professionals working across lighting, audio, and rigging.
