FAQs
The UTS78E3APX is part of the Souriau UTS series and uses a jam nut receptacle with 3 male solder cup contacts. It mates with corresponding UTS receptacles that share the X-keying and 1/3 bayonet coupling. Its compact shell size and standardized insert material enable straightforward integration into existing harnesses, preserving existing layouts while enhancing IP68 protection and contact reliability in harsh environments.
This connector provides a current rating of 7 A (IEC/UL) and a voltage rating of up to 250 V DC/AC depending on region. It operates from -40 °C to 105 °C and features IP68 sealing, UV resistance, and resistance to oil, acid bath, mineral oil, gasoline, and other common industrial fluids. With 3 contacts and gold plating on solder cups, it delivers low contact resistance and robust signal integrity in demanding applications.
Yes. The device is IP68-rated (with IP69K unmated conditions) and UV resistant, designed for continuous exposure to washdowns and outdoor service. Its neoprene insert and plastic shell provide chemical and moisture resilience, while the bayonet coupling enables quick field mating, minimizing exposure during maintenance and reducing downtime in outdoor plants or food-processing environments.
The connector is compliant with IEC 61984, UL 1977, and CSA-C22.2 No.182.3. It also carries ROHS exemption 6.c. These certifications support global procurement, safety verification, and environmental compliance, helping buyers meet international regulatory requirements in automation systems and ensuring traceable product performance across multiple regions.
With a 1/3 bayonet coupling, installation is quick and tool-assisted or tool-free, reducing field time. Mating cycles reach 250, supporting frequent disconnections in dynamic lines. Gold-plated contacts improve longevity and reduce maintenance costs over time, while the robust IP68 sealing limits fault-induced downtime, delivering a favorable total cost of ownership for automated systems.
