Eaton UTS78E98SW Receptacle - IP68 Waterproof Connector
Part Number: UTS78E98SW
Quick Summary
UTS78E98SW is a plastic waterproof IP68/69k connector for rugged industrial wiring and sensor connections. Engineers often struggle with seal integrity and downtime when wiring in wet or dusty environments. This Eaton Souriau design meets UL 1977 and CSA C22.2 No.182.3, and IEC 61984, with RoHS exemption 6.c, IP68 protection, and high durability. Its jam-nut receptacle, 3 gold-plated solder contacts, and 1/3 bayonet coupling simplify installation, reduce maintenance, and improve reliability in automation panels and harsh machines. For engineers evaluating enclosures, the compact footprint and proven mating cycles support scalable, safer designs. By combining seal integrity with fast field servicing, this connector helps reduce downtime and total cost of ownership.

Feature: The UTS78E98SW provides a 7 A current rating at 250 V for a three-contact receptacle. This capability supports typical control signals and small actuators without overdesigning harnesses, enabling compact, cost-efficient panel layouts. Design teams can wire individual circuits with margin for startup surges, reducing the risk of overheating and nuisance trips. Application: automation panels, conveyors, and field devices where space and reliability are critical. Feature: Three gold-plated solder cup contacts deliver low contact resistance and corrosion resistance for stable performance. Impact: longer service life and fewer maintenance events in challenging environments, helping avoid intermittent faults. Application: compact harnesses in robotic arms, sensors, and control lines where secure soldered terminations are required in IP68-rated interfaces. Feature: 1/3 bayonet coupling with jam-nut receptacle ensures fast, vibration-resistant mating and a robust seal. Impact: reduces installation time and rework, preserving IP68 integrity in unmated conditions. Application: machine enclosures, outdoor installations, and washdown environments. Feature: Wide operating temperature range from -40 °C to 105 °C plus UV resistance and RoHS compliance. Impact: extended service life in extreme environments, minimized risk of material degradation, and easier regulatory adherence. Application: outdoor equipment, food processing lines, and industrial machinery. Feature: 250 mating cycles ensure durable performance under frequent connect/disconnect cycles. Impact: lowers replacement frequency and maintenance costs while preserving electrical integrity. Application: robotics, conveyors, and mobile machinery where connectors are cycled often in harsh environments.

FAQs
To install the UTS78E98SW jam-nut receptacle, select the W orientation, thread the jam nut, and tighten to seal the enclosure. Use the 1/3 bayonet coupling to mate with the matching plug, then solder the three gold-plated contacts into the harness. Note that backshells and accessory options are ordered separately; verify IP68 sealing after assembly.
Electrical ratings include 7 A at up to 250 V for each contact, with 250 V test voltage and 7 A test current. With 3 cavities, the total assembly supports multiple circuits in one connector. When designing panels, ensure load distribution across contacts and maintain clearances to meet safety standards.
Yes. The UTS78E98SW carries IP68 protection and IP69K unmated conditioning, plus UV resistance and RoHS-compliant materials. It operates from -40 °C to 105 °C and withstands harsh environments, making it appropriate for outdoor equipment, washdown areas, and exposed industrial machinery while maintaining electrical integrity.
The product complies with UL 1977 and CSA-C22.2 No.182.3, and IEC 61984, with RoHS exemption 6.c. These certifications confirm electrical safety, reliability under wet/dusty conditions, and regulatory alignment for global industrial deployments, reducing risk in audits and helping meet supplier qualification requirements.
With 250 mating cycles and gold-plated contacts, the UTS78E98SW offers durable performance and lower maintenance frequency. This translates to reduced downtime, fewer field failures, and lower total cost of ownership in robotics, conveyors, and mobile automation where frequent connection/disconnection occurs.
