Connector Gland: Cable Range 3-20mm diameter

Component Specifications

Definition

A connector gland is a mechanical fitting designed to provide environmental sealing, cable strain relief, and secure attachment for connectors in industrial applications. In detection heads and apertures, it ensures reliable signal transmission by protecting connections from moisture, dust, vibration, and mechanical stress while maintaining proper alignment and electrical continuity.

Working Principle

The connector gland operates by creating a compression seal around the cable or conduit using internal gaskets, O-rings, or sealing rings. When tightened, it compresses these sealing elements against the cable jacket and housing, forming a barrier against environmental contaminants. Simultaneously, its mechanical clamping mechanism provides strain relief by distributing tensile forces along the cable structure, preventing damage to internal connections.

Materials

Typically constructed from corrosion-resistant materials: brass (nickel-plated), stainless steel (304/316), aluminum (anodized), or engineered plastics (PA66, POM). Sealing elements use EPDM, NBR, silicone, or PTFE for specific chemical/temperature resistance.
