Cable gland

A cable gland protects electrical equipment (for example, cabinet, junction box ) from mechanical influences, dust and moisture by connecting a cable firmly and tightly to the housing. Are customary in metric threads and cable glands with steel conduit thread ( PG), so-called PG cable glands, and, especially in the American market, the self-sealing NPT threads.

For EMC -compliant installation the brass cable glands can be supplemented with EMC operations, which saves the separate storage of special EMC cable glands. In addition, cable glands in the protection of species such as IP66 (dust and protected against water jets ) and IP68 (dust and waterproof) are available to protect humans against potential dangers in their use.

In contrast to the grommet, which is screwed with the housing fixed in the cable gland, a rubber ring.

Specifications

The following are the usual sizes and thread types are led by cable glands:

Detachment of the PG thread

The usual especially in the German -speaking area at Cable Glands PG Cable Glands with tank thread according to DIN standard DIN 40430 ( replaced by DIN EN 60423 ) are permitted only in exceptional cases for new cable glands and are increasingly being replaced by metric threads. Ten old PG sizes have now been replaced by eight new metric sizes. A one-to -one mapping is not possible.
