Eaton UTS78D3ASX32 Plastic Waterproof IP68/69k Connector - IP68/69k
Part Number: UTS78D3ASX32
Quick Summary
The Eaton UTS78D3ASX32 plastic waterproof IP68/69k connector provides rugged, field-ready signal and power connections for harsh industrial environments. Many plants struggle with ingress, corrosion, and unplanned downtime when connectors fail in wet, oily, or high‑vibration conditions. UL 1977, CSA-C22.2 No.182.3 and IEC 61984 certifications help ensure safety, compatibility, and regulatory compliance for control panels and automation gear. Designed for the Souriau UTS series, it uses 3 female PCB contacts with gold plating in a jam‑nut receptacle and 1/3 bayonet coupling, delivering reliability and reduced maintenance for OEMs and integrators.

IP68/69K waterproof rating ensures unmated condition protection for outdoor and wet environments, reducing failure rates and warranty costs. In practice, this means fewer field repairs for control panels exposed to washdown and oil leaks, with seamless integration into existing assemblies. Three gold-plated PCB contacts enable reliable signal and power transfer with low resistance and minimal voltage drop, improving sensor accuracy and equipment uptime in automation networks and robotics. The jam-nut receptacle paired with no backshell option simplifies installation in tight spaces, while the aluminium nut provides robust mechanical mounting, cutting install time and material costs. Operating from -40 °C to 105 °C and rated for 250 mating cycles, the unit supports demanding industrial duty and long service life. Neoprene insert and UV/chemical resistance further extend life in corrosive or sunny environments, reducing maintenance cycles. The 8-shell size and 25.3 mm depth integrate neatly into compact control enclosures and field devices, while the 3-contact, gold-plated PCB configuration ensures compatibility with standard automation boards and sensor arrays.

FAQs
Install the jam-nut receptacle through the panel cutout, secure with the aluminium nut, and tighten to achieve IP68 sealing. The no backshell option simplifies routing in tight spaces, while the X-keying and D3A layout ensure correct orientation and mating alignment with standard Souriau UTS series mating parts.
The connector supports a 7 A current rating per UL/IEC standards, with a test current of 7 A. It is rated for up to 250 V per UL/CSA and 50 V IEC, making it suitable for mixed signal and low-power applications in industrial automation and control systems.
Yes. It carries an IP68 rating (unmated condition) and resistance to gasoline, mineral oil, UV exposure, and various chemicals. The neoprene insert enhances sealing, and the aluminium nut provides robust mounting for outdoor enclosures and rugged machinery in harsh environments.
This UTS series receptacle complies with UL 1977, CSA-C22.2 No.182.3, and IEC 61984. It’s RoHS compliant with exemption 6.c, and is built to perform within the Souriau UTS family guidelines for PCB contacts and bayonet coupling.
With 250 mating cycles and a durable plastic shell, the UTS78D3ASX32 minimizes downtime and maintenance frequency. The sealed IP68 design reduces ingress-related failures, lowering spare parts usage and extending intervals between panel refurbishments in demanding manufacturing and outdoor installations.
