In addition to the secure connection of electrical conductors in the connector is also the supply of the cable is of crucial importance for the quality of the connection. In practice, there is a variety of demands on this interface. By Deltron backshell with integrated cable gland these requirements can be implemented quickly and flexibly. Advantages over the use of an end housing with PG / M adapter and a separate cable gland are the faster and more secure mounting, and the absence of a sealing point, the reduced number of components and the modular design for individual solutions with standard components. The gland is based on the system UNI sealing, all components can be adapted to the Deltron system.
