Description
1. Product Overview
The Clifnor PG-Series is a high-performance cable entry solution designed for industrial machinery and electrical enclosures following the German DIN 40430 standard. Engineered with a rugged nickel-plated brass body and an advanced Nylon PA clamping system, these glands provide a permanent, liquid-tight seal. They are specifically built to offer superior strain relief and vibration resistance in heavy-duty industrial environments.

3. Engineering & Performance Advantages
-
Optimized Sealing Geometry: The specialized claw and seal design allows for a wider cable clamping range while maintaining a uniform, 360-degree grip that prevents cable jacket deformation and ensures IP68 integrity.
-
Audible “Click” Locking: The sealing nut is engineered with a tactile feedback mechanism. This ensures the installer that the gland is fully torqued, preventing accidental loosening due to thermal expansion or industrial vibrations.
-
Superior Chemical Resistance: The nickel-plated finish provides a resilient shield against salt spray, weak acids, alcohols, industrial oils, and common solvents.
-
Mechanical Durability: The high-tensile brass body is designed to withstand mechanical impacts and harsh atmospheric conditions, outperforming standard plastic alternatives in longevity.
4. Strategic Industry Applications
-
Industrial Control Panels: Reliable cable entry for PLC cabinets and junction boxes.
-
European Machinery (OEM): Standard connectivity for motors, sensors, and actuators in DIN-compliant equipment.
-
Marine & Coastal Systems: Weatherproof sealing for port infrastructure and shipboard electronics.
-
Telecommunications: Secure housing for outdoor base stations and signal distribution units.
