Eaton UTS78D2SW connector - IP68/69K waterproof
Part Number: UTS78D2SW
Quick Summary
The UTS78D2SW is a plastic waterproof IP68/69K connector designed for reliable PCB-to-receptacle interfaces in harsh industrial environments. This helps engineers reduce moisture ingress and corrosion risks that commonly drive field failures and downtime. Compliant with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with ROHS exemption 6.c, the solution balances performance with regulatory alignment. By combining a compact jam nut receptacle, gold-plated PCB contacts, and a 1/3 bayonet coupling, it delivers durable, serviceable connectivity for automation cabinets, outdoor equipment, and rugged machinery. The resulting uptime translates to lower maintenance costs and improved overall equipment effectiveness (OEE) for manufacturing lines and process plants.

FAQs
The UTS78D2SW is rated IP68, providing robust protection against dust and water ingress in unmated conditions. It delivers UV resistance, chemical resistance, and a wide operating temperature range (-40 °C to 105 °C), making it suitable for outdoor installations, exposed enclosures, and machinery operating in demanding environments.
This receptacle supports a 7 A current rating (UL/IEC) with a test current specification matching that value. It offers up to 250 mating cycles, enabling reliable service life for equipment that requires frequent mating and unmating, such as maintenance carts, robotic grippers, and modular automation panels.
No backshell option is available for this receptacle. The design uses a jam nut receptacle with 1/3 bayonet coupling, which simplifies installation in compact spaces but means you should plan separate protection or shielding strategies if backshell protection is required in your design.
The connector measures 25.3 mm in depth, with 24 mm width and 24 mm height. It is a 2-pin receptacle with shell size 8 and a jam nut mounting style. The W orientation and 1/3 bayonet coupling facilitate alignment and mating in tight assemblies, common in compact automation panels.
Compliances include IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with ROHS exemption 6.c. These certifications support regulatory compliance for industrial automation, electrical assemblies, and safety-critical applications across North America and Europe.
