Eaton UTS78D3P Receptacle - IP68/69K
Part Number: UTS78D3P
Quick Summary
The Eaton Souriau UTS series plastic waterproof IP68/69k connector offers reliable PCB connections for harsh industrial environments. A common pain point is field-water ingress and time-consuming assemblies; this jam-nut receptacle design minimizes both—with no backshell required. Compliances include IEC 61984, UL 1977, and CSA-C22.2 No.182.3, while IP68 sealing remains effective in unmated conditions. With 3 gold-plated PCB contacts and a compact 25.3 mm length, it fits densely populated panels and preserves signal integrity. Used in industrial automation panels and outdoor equipment, it helps reduce downtime and total cost of ownership.

IP68/IP69K sealing and rugged plastic shell protect signals and power in wet, dusty, and vibration-prone environments. This capability reduces field failures and service calls, delivering higher equipment uptime and lower lifecycle costs. It is well suited for outdoor panels, conveyors, and industrial machines where ingress protection is essential. Three PCB contacts with gold plating deliver low contact resistance and superior corrosion resistance in challenging conditions. The loaded contact delivery ensures the connector arrives ready to mate, saving assembly steps and improving PCB reliability. This combination supports precise signal transmission and stable power delivery in automation controls. Bayonet coupling with jam nut receptacle simplifies installation and tightening without a backshell, reducing installation time and panel footprint. The 25.3 mm length and 24 mm width/height fit compact enclosures and maintain a neat, reliable interface. Mating remains robust under vibration, thanks to the 1/3 Bayonet coupling design. Operating from -40 °C to 105 °C enables operation across cold-start conditions to hot factory floors, expanding application scope. The neoprene insert and aluminum nut provide chemical resistance and structural stability, while UV resistance helps long outdoor exposure with no degradation after years in natural environments. With 250 mating cycles and a 7 A current rating at up to 250 V, the UTS78D3P supports frequent hot-swaps in automation panels without compromise. Gold-plated PCB contacts reduce oxidation and maintain performance across cycles, while the jam-nut receptacle design minimizes maintenance intervals.

FAQs
The UTS78D3P is designed as a jam-nut receptacle with no backshell option, simplifying installation and reducing panel depth. This design is ideal when you need a compact, sealed interface directly mounted to a PCB or panel cutout. If a backshell is required for cable protection, you may need to select an alternative configuration or accessory compatible with your enclosure.
This connector supports 7 A current rating and is rated up to 250 V across CSA and UL standards, with a separate IEC rating of 32 V. The combination ensures reliable power delivery for typical automation and control circuits while maintaining safety margins for industrial use. Gold-plated PCB contacts help maintain low contact resistance through many mating cycles.
The IP68 sealing, inline jam-nut receptacle, and plastic shell make the UTS78D3P ideal for outdoor equipment, conveyors, and rugged automation panels where exposure to moisture, dust, and UV is common. Its wide operating temperature range (-40 °C to 105 °C) supports cold-start conditions and hot factory floors, ensuring functionality across diverse production environments.
Key references include IEC 61984 and UL 1977 for connector safety and reliability, CSA-C22.2 No.182.3 for Canadian standards, and ROHS exemptions where applicable. The product also carries UL94 HB flammability classification and UV/chemical resistance features suitable for harsh environments. These certifications help satisfy regulatory, procurement, and end-user quality requirements.
With three mating cycles rated at 250 and durable gold-plated PCB contacts, the connector supports repeated servicing without significant performance loss. The jam-nut receptacle design reduces maintenance steps by enabling quick, secure mounting. Its resin insert, aluminum nut, and UV resistance contribute to longevity in outdoor or demanding industrial settings, lowering total cost of ownership over time.
