IP68/IP69K sealing protects against water ingress and dust in outdoor automation equipment. The jam-nut receptacle design simplifies panel mounting and sealing, reducing assembly steps and potential leaks. Four gold-plated solder cup contacts deliver reliable signal and power transfer, with a 7 A current rating and a 250 V rating that support control circuits and sensor interfaces in compact layouts. The 1/3 bayonet coupling enables quick, vibration-resistant mating, while maintaining durable mating cycles up to 250 for both mobile and stationary equipment. The operating temperature range of -40 to 105 °C ensures operation in extreme environments, with UV resistance and chemical compatibility that stand up to mineral oil, gasoline, and acid baths. Backshell is not delivered and must be ordered separately, allowing you to tailor accessories to your enclosure and routing needs. Compliance with IEC 61984, UL 1977, CSA-C22.2 No.182.3 and RoHS exemption 6.c provides regulatory confidence and market readiness, while the plastic shell and aluminium nut promote cost-efficient maintenance over the product life cycle.
