Eaton UTS78E2S Receptacle Connector - IP68/69K
Part Number: UTS78E2S
Quick Summary
The Eaton Souriau UTS78E2S is a plastic waterproof IP68/69K receptacle connector designed for harsh environments. Engineers often battle water ingress and corrosion when field seals fail, so a proven unmated seal helps prevent leaks in coastal, muddy, or dusty environments. Key certifications include IEC 61984 and UL 1977, plus ROHS exemption 6.c, offering safety and environmental assurance. As part of the Souriau UTS family, this connector supports fast installation and reliable performance in industrial automation and outdoor equipment. The compact form factors — 25.3 mm length, 24 mm width, 24 mm height — and a 7.1 g weight enable easy panel mounting. With two gold-plated solder contacts and a 7 A rating, it delivers consistent electrical performance across demanding applications. This combination supports predictable maintenance cycles and reduced downtime in industrial automation and outdoor equipment.

IP68/69K waterproof performance in unmated conditions prevents water and dust ingress during vibration and outdoor exposure, reducing field repair costs and extending component life in harsh environments. Two gold-plated solder cup contacts provide a low-resistance, corrosion-resistant connection, enabling reliable power and signal transfer in compact designs for robotics, motors, and control panels. The 1/3 bayonet coupling allows quick, tool-free mating with consistent alignment, while the jam nut receptacle design and the option to use a separate backshell support secure, sealed installations in limited-access equipment. The plastic shell and neoprene insert offer chemical resistance and UV stability, with a broad operating range from -40 °C to 105 °C to endure extreme climates. Mating cycles of up to 250 and a small 25.3 mm length footprint reduce maintenance frequency and support lightweight, space-constrained assemblies. Compliance with IEC 61984 and UL 1977, along with ROHS exemption 6.c, minimizes regulatory risk while maintaining performance for 7 A at up to 250 V, making this connector suitable for demanding industrial and outdoor applications.

FAQs
The UTS78E2S is a jam-nut receptacle designed for panels. Align the connector, secure it with the jam nut from the panel side, and mate using the 1/3 bayonet coupling. Note that the backshell is not included, so order the appropriate connector accessory separately to achieve full environmental sealing and strain relief where required. The unit is loaded with two female solder contacts for a clean, compact two-circuit connection.
The connector is rated for 7 A per IEC and UL standards, with a test current of 7 A. It supports up to 250 V (UL) and 32 V (IEC) across its two solder cup contacts. The mating arrangement uses a 1/3 bayonet coupling, and the contacts are gold-plated for low resistance and corrosion resistance, suitable for demanding industrial environments.
Yes. It carries IP68 sealing in unmated conditions and is UV resistant, with resistance to oils, basic baths, acids, and mineral oils. The insert material neoprene and plastic shell provide additional environmental resilience, making it well-suited for outdoor automation, agriculture, and marine-related equipment where exposure to weather and chemicals is common.
This connector complies with IEC 61984 and UL 1977. It also aligns with ROHS exemption 6.c and CSA-C22.2 No.182.3, providing safety, environmental compliance, and reliability for industrial installations and cross-border projects. When integrating into certified systems, these standards help maintain regulatory alignment and supplier qualification.
With up to 250 mating cycles and a compact profile, the UTS78E2S reduces downtime and replacement frequency in rugged environments. Gold-plated contacts ensure durable electrical performance, while IP68/69K sealing minimizes maintenance needs related to ingress. The combination of fast mating with a robust, corrosion-resistant interface translates to lower total cost of ownership in automation, robotics, and outdoor equipment projects.
