Some of the major PT series specifications are shown here. Shell, coupling nut and rear hardware are made from aluminum, typically either die cast or machined. Current range is 7.5 to 23 amps per circuit depending on contact size with a maximum voltage rating of 1000 VAC. Contact termination is either crimp or solder and the contacts are gold plated for maximum efficiency, especially in signal applications. The insert material is neoprene which seals the connector which helps allow for an operating temperature range of -55ºC to 125ºC and more than 500 mating cycles. An IP67 rating is realized when using an “E” service class plug and receptacle in the mated condition.
