Eaton UTS78D3SW32 Receptacle - IP68/69K
Part Number: UTS78D3SW32
Quick Summary
UTS78D3SW32 is a waterproof PCB receptacle connector designed for rugged industrial equipment enclosures. Engineers often struggle with sealing, vibration, and maintenance in outdoor or mobile installations. This Eaton Souriau solution combines IP68/69K protection with UL 1977, IEC 61984, and CSA-C22.2 No.182.3 compliance to deliver reliable field performance. By integrating a jam-nut receptacle, neoprene insert, and gold-plated PCB contacts, it simplifies installation while reducing downtime and enabling panel-level integration. With a 7 A rating and a wide operating range from -40 °C to 105 °C, it supports control and sensing circuits across harsh environments, helping procurement consolidate supply chains and shorten lead times.

Sealing and environmental resistance: The IP68/69K rating delivers durable protection against dust, water, and immersion in unmated conditions. This translates to extended equipment life in harsh environments, reduced field maintenance, and lower total cost of ownership for outdoor automation systems. The UV and chemical resistance (oil, mineral oil, acid/basic baths) further extends service intervals for conveyors and outdoor machinery. Electrical reliability is enhanced by robust contact materials and plating, minimizing contact wear in vibration-prone installations. 3 PCB contacts with gold plating ensure signal integrity for control and sensing circuits, supporting precise feedback in automated lines. The thermal range of -40 °C to 105 °C enables operation across cold enclosures and high-dwell-temperature panels, reducing the need for climate-controlled housing in remote locations.

FAQs
This jam-nut receptacle uses a panel cutout sized for a compact 25.3 mm depth and 24 mm square footprint. Align the connector, insert the three PCB contact pins, and tighten the jam nut from the exterior to secure the housing. The installation leverages the W orientation for correct alignment and does not require a backshell, simplifying field assembly and reducing accessory counts.
The connector is rated for 7 A per UL/IEC/CSA, with a maximum voltage of 250 V (UL/CSA) across three PCB contacts. It supports up to 250 V testing and 7 A currents, with 3 cavities and gold-plated PCB contacts for reliable signal transfer. Mating cycles are specified at 250, ensuring repeatable performance in recurring connect/disconnect cycles.
Yes. The IP68 rating (IP68/69K unmated) coupled with UV resistance and chemical resistance (acids, bases, oils) makes it well-suited for outdoor enclosures and mobile machinery. Its operating temperature range of -40 °C to 105 °C supports harsh environments typical of outdoor automation, construction equipment, and conveying systems, reducing downtime due to environmental exposure.
The UTS78D3SW32 complies with UL 1977, IEC 61984, and CSA-C22.2 No.182.3, with RoHS exemption 6.c. These certifications confirm safety, electrical interoperability, and environmental compliance, streamlining procurement for regulated industries and enabling easy integration into certified systems without additional validation work.
Projected ROI comes from reduced maintenance, faster field installations, and longer life in demanding environments. With 7 A at 250 V, a compact 25.3 mm depth, gold-plated contacts, and 250 mating cycles, you gain reliable performance, lower spare-part variety, and fewer downtime events in harsh settings, all while meeting key industry standards.
