An Un Armored Cable Gland is a cable entry device specifically engineered for non‑armoured cables, providing strain relief, environmental sealing, and electrical continuity where required, without the need to grip any armour layer. In practical terms, engineers rely on Un Armoured Cable Glands for PLC panels, control cabinets, instrumentation skids, building automation, and low‑mechanical‑stress power or signal circuits. Unlike armoured glands, the design is lighter and less complex, but correct sizing, thread engagement, and gasket quality are critical to maintaining IP protection and preventing water or dust ingress. The 2024 revision of IEC 60079‑14 has tightened requirements on barrier sealing, IP validation, and material compatibility for cable entry systems, which directly impacts how Un Armoured Cable Glands must be specified in Ex areas. When drafting specifications, always link the Un Armoured Cable Gland to the exact cable construction, enclosure type, zone classification, and applicable standards to ensure a safe, future‑proof installation.
