NVENT HOFFMAN CED50 Double protection gland M50

Why Choose the nVent HOFFMAN CED50 Double Protection Gland?

The nVent HOFFMAN CED50 is an M50 double-protection cable entry gland designed to provide simple, reliable cable and pipe entry into electrical enclosures while maintaining a high level of ingress protection. Manufactured from halogen-free EPDM rubber, it combines flexible installation with an IP67 protection rating for demanding industrial enclosure applications.

Unlike conventional threaded cable glands, the CED50 uses a practical push-fit grommet design that can be installed without tools. An integral push-out membrane remains permanently sealed until penetrated by the cable or pipe, while the double-layer sock surrounding the cable provides two independent protective layers to help preserve the enclosure's protection degree even if the outer layer becomes damaged.

The CED50 accommodates cables with diameters from 27–35 mm and fits a 50.5 mm mounting hole in materials between 0.5–4 mm thick. With a temperature resistance of -40 °C to +110 °C, an overall diameter of 60.5 mm and a RAL 7035 finish, it provides a versatile cable-entry solution for electrical cabinets, control panels and industrial enclosures.

Double-Layer Cable Entry Protection for Electrical Enclosures

Cable entry points can become vulnerable areas in an electrical enclosure, particularly where cables are exposed to water, contamination or mechanical disturbance. The nVent HOFFMAN CED design addresses this with an exterior and interior sealing layer that operate independently, helping maintain the enclosure's protection degree even if the outer layer is damaged by external conditions.

The CED50 is particularly useful where straightforward installation and dependable sealing are required. Its push-fit design eliminates the need for conventional gland assembly tools, while the integral membrane keeps an unused entry sealed until installation. Once penetrated, the double-layer sock fits around the cable, providing an effective IP67 cable-entry solution for straight cable and pipe runs.

Typical Applications

• Electrical control cabinets and industrial enclosures.
• Machine-building and factory automation equipment.
• Power distribution and switchgear enclosures.
• Industrial cable and pipe entry points.
• Outdoor and demanding industrial enclosure installations.
• Applications requiring tool-free IP67 cable entry.
