Explosion-proof cable glands are used on equipment where an explosion may occur, as well as at industrial facilities, in automation systems, electronics, robotics, in places where sealing of the IP 66/67/68 cable sheath is required.

The increasing digitalization and pervasive adoption of Industrial Internet of Things (IIoT) technologies in hazardous areas  fundamentally necessitate a more profound understanding and sophisticated application of explosion-proof components for data networks. This evolving landscape shifts the focus from merely ensuring power integrity to guaranteeing both explosion safety and reliable, real-time data flow, which is foundational for advanced automation, predictive maintenance, and remote operational control. This expansion of requirements means that industrial processes are becoming increasingly data-driven, and cable glands, which serve as critical physical interfaces, must not only prevent electrical ignition and contain explosions but also ensure the unimpeded and accurate transmission of high-frequency data signals (Cat5e, Cat6, Cat7). This dual requirement necessitates a re-evaluation of design, selection, and installation practices to encompass signal integrity, electromagnetic compatibility (EMC), and compatibility with specific data cable characteristics, representing a significant technical and operational challenge beyond traditional electrical safety. 

Twisted pair is one of the components of modern structured cabling systems. It is used in telecommunications and computer networks as a physical signal transmission medium in many technologies, including Ethernet. Currently, due to its low cost and ease of installation, it is the most common solution for building wired (cable) local networks. The cable consists of several pairs of insulated conductors twisted together (with a small number of turns per unit length), covered with a plastic sheath. Aluminum foil and copper braid are also used to shield the cable and individual pairs for additional EMI protection. There are voids in the cables, which makes it difficult to use in explosive areas. Sometimes, the voids in the cables are filled with water-repellent gel, but this is not enough for safe entry, especially in Exd enclosures.

Explosion-proof cable glands of the Ethernet  series with a special seal are designed to enter 4-pair twisted pair in Ex d enclosures.
