CMP E1FX M20 Nickel-Plated Brass Cable Gland
The CMP E1FX-M20 is an internationally approved, heavy-duty industrial cable gland designed for explosive atmospheres and hazardous locations. This premium gland features a high-quality, electroless nickel-plated brass construction that delivers exceptional corrosion resistance and mechanical strength.
The E1FX series is purpose-engineered to terminate armored cables—specifically those featuring single wire braid, wire braid armor (e.g., SWB), steel tape armor (STA), or aluminum strip armor. It provides independent metal-to-metal armor clamping, continuous earth conductivity, and reliable dual-environmental seals.
Key Features
-
Dual Sealing Technology: Incorporates a displacement-type flameproof inner seal on the cable bedding and a controlled outer “Load Retention Seal” (LRS) on the outer sheath to prevent moisture ingress and safeguard against environmental elements.
-
Advanced Armor Clamping: Employs a detachable armor cone and an “AnyWay” universal clamping ring arrangement. This design allows mechanical termination, continuity checkups, and remote make-off where the cable can be disconnected from equipment without disturbing the armor lock.
-
Coldflow Prevention Layout: Carefully structured to reduce the structural effects of coldflow on the cable’s inner bedding insulation layers, ensuring long-term electrical safety.
-
Unique OSTG Prevention: Outfitted with CMP’s unique Outer Seal Tightening Guide (OSTG) visual indicator, which physically prevents installers from overtightening the gland and distorting the internal sealing rings.
-
Superior EMC Performance: The robust metal-to-metal contact established by the braided armor clamping mechanism delivers outstanding electromagnetic compatibility shielding performance.

Applications
-
Hazardous Area Enclosures: Installed onto Ex d (Flameproof), Ex e (Increased Safety), and Ex nR (Restricted Breathing) electrical junction boxes, control panels, and motor terminal enclosures.
-
Oil, Gas, & Petrochemical Plants: Widely deployed on offshore rigs, oil refineries, and chemical processing facilities to terminate braided power and instrument control lines in corrosive marine environments.
-
Heavy Marine & Shipboard Cabling: Used alongside certified marine shipboard wire-braid cables to provide grounding bonds and robust watertight entry into utility decks.
-
Industrial Automation & Processing: Provides superior EMC shield grounding inside automated heavy factories, preventing high-frequency noise from variable speed drives (VFDs) from disrupting nearby control telemetry.
