Eaton UTS78D2S Receptacle - IP68/69K Waterproof
Part Number: UTS78D2S
Quick Summary
Eaton UTS78D2S receptacle is a plastic waterproof connector designed for PCB-based assemblies in harsh outdoor and industrial environments. Engineers often wrestle with ingress protection, tight spaces, and limited backshell options, which can complicate sealing and reliability. This jam nut receptacle delivers IP68 (unmated) performance and robust electrical contact with gold-plated PCB sockets, backed by UL 1977, CSA-C22.2 No.182.3, and IEC 61984 standards. In practice, it helps reduce field failures and maintenance cycles while enabling compact, high-density layouts. By integrating with compact PCBs and 1/3 bayonet coupling, it supports efficient installation in equipment enclosures, robotics, and field dashboards without compromising reliability or compliance.

Feature → Business Impact → Application: The UTS78D2S uses a jam nut receptacle with 2 gold-plated PCB contacts, delivering reliable signal integrity in space-constrained panels, reducing contact resistance drift and maintenance costs in additive manufacturing, packaging lines, and field instrumentation. Application: Ideal for compact PCB-to-mating interface in outdoor enclosures where IP68 sealing is mandatory and where 2-contact PCBs must fit through tight seams without a backshell. Feature → Business Impact → Application: 1/3 bayonet coupling provides quick, vibration-resistant mating, improving installation speed and uptime in mobile equipment and agricultural machinery. Application: Fits 7 A rated circuits with 250 mating cycles for predictable lifecycle performance in conveyor controls and remote telemetry hubs. Feature → Business Impact → Application: Neoprene insert and plastic shell offer UV resistance and broad temperature tolerance, enabling use from -40 °C to 105 °C. Application: Suitable for automotive, rail, and industrial automation devices exposed to heat, dust, and UV exposure. Feature → Business Impact → Application: Gold-plated PCB contacts ensure low contact resistance and corrosion resistance, extending service life in coastal or chemical environments. Application: Critical for PCB connectors in water-resistant camera housings, sensor arrays, and control panels where signal integrity is essential. The product’s 24 mm width, 24 mm height, and 25.3 mm length support compact layouts, while its 7 A current rating and 250 mating cycles provide dependable performance in demanding industrial settings.

FAQs
Installation involves aligning the 2 PCB contacts with the board’s footprint, securing the jam nut receptacle directly to the panel, and using the 1/3 bayonet coupling to mate with the corresponding insert. No backshell is provided, so ensure proper sealing with the neoprene insert and gasket to maintain IP68 protection during assembly and service.
IP68 rating applies in unmated conditions, with a UV-resistant neoprene insert and robust plastic shell that withstands oil, gasoline, and mineral oil exposure. The connector is designed for vibration from 10 to 2000 Hz and supports 7 A at multiple voltages, enabling reliable performance in harsh industrial environments.
Yes, the unit uses 2 PCB contacts in a 2-position layout and a jam-nut receptacle design suitable for compact PCBs. The mating cycle specification of 250 ensures repeatable connections, while the 25.3 mm length and 24 mm width/height support space-constrained housings and panel layouts.
The UTS78D2S is associated with UL 1977, CSA-C22.2 No.182.3, and IEC 61984 certifications, along with RoHS compliance. These standards validate safety, reliability, and environmental compliance for industrial automation and electrical equipment used in global markets.
With 250 mating cycles and gold-plated PCB contacts, the UTS78D2S offers low contact resistance drift and longer service life, reducing maintenance frequency. Its IP68 sealing and rugged UV-resistant housing minimize field failures, lowering downtime and total cost of ownership in harsh outdoor or coastal environments.
