Manschettendurchführungen

Manschettendurchführungen, also known as cable glands or strain reliefs, are components used to seal and protect electrical cable entries into enclosures. They are designed to pass a cable through a wall, panel, or housing while maintaining a seal against environmental factors such as dust, water, and oil. A primary function is to prevent the cable from being pulled or twisted, thereby protecting the conductors and connections from mechanical stress.

These devices typically consist of a threaded body, a sealing nut, and a clamping sleeve or collet. The cable is inserted through the gland, and as the sealing nut is tightened, it compresses the collet around the cable sheath, creating a watertight and dust-tight seal. The threaded portion of the gland allows it to be securely screwed into a pre-drilled hole in the enclosure.

Manschettendurchführungen are manufactured from various materials, including plastic (like polyamide) and metal (such as brass or stainless steel), to suit different environmental conditions and application requirements. They come in a wide range of sizes to accommodate different cable diameters and thread sizes. Their application is widespread across industries, including manufacturing, automation, telecommunications, and outdoor equipment, where reliable cable protection and sealing are essential.
