Quick Summary

Eaton UTS78D33P is a waterproof plastic receptacle connector used for rugged PCB connections in demanding industrial applications. However, engineers often face ingress, moisture paths, and limited backshell options in compact assemblies, risking maintenance downtime. The UTS78D33P meets UL 1977 and IEC 61984 standards, offers ROHS exemptions, and carries IP68/IP69K protection for harsh environments. As part of the Souriau UTS series, the jam-nut receptacle with 3 male PCB contacts delivers reliable sealing, straightforward mounting, and cost-effective field servicing. This translates to reduced total cost of ownership and improved system uptime while enabling compact, compliant, and scalable panel designs. Designed for high vibration and outdoor use, the connector ensures predictable performance across the temperature range.

IP68/IP69K protection and a compact jam-nut design deliver a sealed, vibration-resistant connection that minimizes ingress and maintenance in outdoor or washdown environments. Business impact: significantly reduced field repairs and downtime, enabling longer intervals between service windows and lower total cost of ownership. Application: perfect for rugged automation equipment and machinery exposed to dust, moisture, or chemical exposure. The 1/3 bayonet coupling enables quick mating and reliable retention under shock and vibration, improving line efficiency during assembly or field servicing. With 3 gold-plated PCB contacts and loaded contact delivery, you get low contact resistance, stable signal integrity, and predictable performance across 250 mating cycles. This translates to consistent performance in robotics, packaging, and process automation where uptime matters. Compatibility and installation are simplified by a standard 25.3 mm depth and 24x24 mm shell, reducing space and hardware while maintaining robust sealing. Environmental resistance, including gasoline, mineral oil, UV exposure, and salt spray tolerance, supports long life in harsh environments—so teams can design toward longer device lifecycles and reduced maintenance costs. The option of no backshell further reduces complexity and cost in compact panels, while the aluminum nut provides secure mounting at a predictable torque, avoiding over-tightening and material fatigue. In practice, engineers report smoother installations when integrating the UTS series with existing Souriau components, thanks to consistent mating geometry and documented performance under vibration. Overall, these features align with industry expectations for reliable, compliant, and scalable connector solutions in heavy equipment and equipment bays.

FAQs

The UTS78D33P is a jam-nut receptacle designed for panel mounting without a backshell. Its compact shell measures 24 mm by 24 mm with a 25.3 mm depth, and the aluminum nut provides a secure, load-bearing fit. There is no backshell accessory for this variant, which simplifies installation and reduces cost in compact, sealed assemblies.
The connector supports a 7 A current rating and 250 V operating voltage (UL/CSA). It uses gold-plated PCB contacts and provides a 3-contact configuration with loaded contact delivery. Mating cycles are rated at 250, indicating suitability for frequent connect/disconnect in manufacturing lines while maintaining low contact resistance and stable signal transmission.
Yes. The UTS78D33P is IP68 rated (and IP69K in unmated conditions) and operates from -40 °C to 105 °C, making it well-suited for outdoor, washdown, and vibration-prone environments. Its resistance to UV, oils, and basic baths further supports long-term reliability in harsh industrial settings.
Industries like industrial automation, packaging lines, agricultural equipment, outdoor machinery, and robotics benefit from the UTS series due to compact form factor, rugged sealing, and reliable PCB contacts. The 3-pin configuration and 1/3 bayonet coupling streamline installation in tight panels while maintaining high ingress protection and vibration resistance.
Key certifications include UL 1977, IEC 61984, and ROHS exemptions, along with CSA-C22.2 No.182.3 compliance. These ensure safety, electrical performance, and environmental responsibility. The IP68/IP69K rating and Souriau UTS series heritage provide confidence for use in harsh industrial environments and regulated applications.
