FAQs
The UTS78E3AP uses a 1/3 bayonet coupling and is a jam nut receptacle designed for 3-pin solder cup contacts. It mates with Souriau UTS series plugs and offers a secure, fast connection with reliable sealing. This design supports easy harness integration and straightforward field diagnostics without backshell (backshell can be ordered separately).
This connector complies with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, ensuring safety, interconnect reliability, and compatibility within North American and international systems. These certifications simplify regulatory approvals, support quality audits, and provide confidence when deploying in harsh industrial environments.
IP68/69K protection seals the interface against dust, water, and high-pressure washdowns, enabling reliable operation in outdoors, vehicle-mounted, and mobile equipment. This minimizes ingress-related failures, reduces maintenance, and enhances uptime in challenging environments where exposure to moisture and vibration is common.
Plan for the jam nut mounting method and the option to order backshell accessories separately if needed. The connector is oriented for a straight N configuration and accommodates 3 contacts with gold plating. Ensure mating components are compatible with the UTS series and verify torque specifications for the jam nut to maintain IP68 integrity.
With a mating life of about 250 cycles and a 7 A current rating, the UTS78E3AP supports durable network connections in fluctuating loads. Its corrosion-resistant gold-plated contacts and neoprene insert help sustain performance over time, reducing the frequency of replacements and lowering total cost of ownership in automation and control panels.
