Cable Gland/Connector Port: Cable Diameter Range 3mm to 40mm

Component Specifications

Definition

A cable gland, also known as a connector port, is a mechanical device designed to attach and secure the end of an electrical cable to equipment, providing strain relief, environmental sealing (against dust, moisture, and chemicals), and maintaining the integrity of electrical enclosures. It ensures safe and reliable cable entry into mechanical housings while preventing cable pull-out and protecting internal components from external contaminants.

Working Principle

The cable gland works by mechanically clamping the cable's outer sheath between a compression nut and a sealing ring or cone, creating a tight seal. It typically includes a threaded body that screws into a housing port, with internal components that compress against the cable as the nut is tightened, providing both mechanical retention and environmental protection. Some designs incorporate additional features like grounding continuity or EMC shielding.

Materials

Common materials include brass (for general use), stainless steel (AISI 304/316 for corrosive environments), nickel-plated brass, aluminum, and plastic (PA6, PA66, or PVDF for chemical resistance). Sealing elements are typically made from nitrile rubber (NBR), silicone, EPDM, or neoprene, depending on temperature and chemical exposure requirements.

Frequently Asked Questions

What is the difference between a cable gland and a connector?

A cable gland primarily provides sealing and strain relief for cable entry into enclosures, while a connector facilitates electrical mating between cables or devices. Some products combine both functions.

How do I select the right cable gland for my application?

Consider cable diameter, thread size, IP rating, material compatibility (environmental exposure), and certifications (e.g., ATEX for hazardous areas). Always match the gland to the cable's outer diameter and the housing's thread specification.
