Cable gland with integrated pressure equalisation function

Condensation is very often the cause of short circuits in electronic enclosures and other electronic or electrical components, and hence responsible for costly machine failure. The pressure equalisation screw connections from RST combine the features of a pressure equalisation element with those of a cable gland. That means they prevent the formation of condensation and at the same time ensure that the cable connection to the housing is dust- and watertight - IP66/67. This is guaranteed by the air vent filter made of PTFE in the neck of the screw connection. An extra bore hole and installation of a pressure equalisation element can be dispensed with. The pressure equalisation screw connection is available in polyamide or nickel-plated brass, in the sizes M12, M16 and M20.
