FAQs
UTS78E3ASW is a jam-nut receptacle designed for Souriau UTS series mates. Use a compatible UTS mate with a 1/3 Bayonet coupling and align keying W for proper engagement. Ensure the insert and gasket are seated, then tighten the jam nut to spec for full IP68/69K sealing. Use approved crimping or solder methods as specified by Eaton.
The connector is rated for 7 A current with a voltage rating of up to 250 V (UL/CSA). The IEC rating is 50 V for certain applications, but for standard power or control wiring in North America, plan for 250 V or per your system requirements. Gold-plated solder cup contacts support reliable performance under load.
Yes. The UTS78E3ASW features IP68 sealing and is designed for unmated IP conditions, making it suitable for outdoor, wash-down, and harsh environments. It also withstands UV exposure and chemical challenges as indicated by its resistance properties and RoHS compliance.
This connector aligns with UL 1977, CSA-C22.2 No.182.3, and IEC 61984, with RoHS exemption 6.c. These certifications support regulatory compliance, safety, and reliability for industrial automation, ensuring the part meets essential electrical and environmental requirements for control panels and field wiring.
With 250 mating cycles and robust sealing, maintenance intervals can be extended, reducing downtime. The gold-plated contacts minimize corrosion and resistance drift, improving uptime and signal integrity. Over multiple years, this translates to lower replacement costs and predictable maintenance budgeting for automated lines and equipment fleets.
