Eaton UTS78D33SW Receptacle - IP68/69K Waterproof
Part Number: UTS78D33SW
Quick Summary
Eaton UTS78D33SW Receptacle is a plastic waterproof connector designed for sealed PCB interconnects in harsh industrial environments. This solution helps minimize downtime by resisting washdowns and moisture ingress that threaten critical automation networks. The device carries UL 1977, IEC 61984, and CSA C22.2 No. 182.3 certifications, along with RoHS exemption 6.c, and achieves an IP68 rating for unmated conditions. It supports reliable operation across -40 to 105 °C, and its 7 A/250 V ratings align with common control panel needs. By combining a compact jam-nut form with 3 gold-plated PCB contacts, it enables robust, maintenance-friendly installations that translate into lower lifecycle costs and increased equipment uptime.

IP68/IP69K protection ensures reliable sealing in washdown and outdoor environments, reducing field failures and service calls and enabling safer operation of automated machinery. The 3-position PCB contact arrangement with gold plating minimizes contact resistance and improves longevity, delivering stable power and signals to control panels and robotics subsystems. A 1/3 bayonet coupling offers quick, secure mating, speeding assembly and maintenance while maintaining vibration resistance in mobile equipment. The jam-nut receptacle design with an aluminum nut supports consistent gasket compression and reduced harness complexity, lowering installation time and potential misalignment. Operating from -40 to 105 °C extends service life in extreme environments, while 250 mating cycles provide predictability for frequent field servicing and reconfigurations. Compatibility with Souriau UTS series simplifies spares, and the overall footprint supports compact control panels with robust IP-rated interfaces.

FAQs
The part is a Jam Nut Receptacle with a 3-contact PCB configuration designed for direct panel mounting. Its 25.3 mm depth and 24 mm x 24 mm footprint fit common control-panel layouts, and the aluminum nut provides secure mounting with consistent gasket compression for reliable long-term sealing.
This connector is compliant with UL 1977, IEC 61984, and CSA C22.2 No. 182.3, with RoHS exemption 6.c. These certifications validate safety, interoperability, and material compliance for industrial interoperability, while IP68 rating confirms ingress protection in harsh environments.
IP68 protection in unmated conditions, oil and gasoline resistance, UV durability, and a broad -40 °C to 105 °C operating range collectively ensure reliable performance in outdoor, wet, or washdown environments typical of outdoor machinery and process equipment.
The connector provides 7 A at up to 250 V (CSA/UL), with 250 mating cycles. Gold-plated PCB contacts minimize contact resistance and corrosion, supporting stable electrical performance over repeated mating and unmating cycles.
This is a jam-nut receptacle with no backshell option, designed for straightforward mounting with an aluminum nut. It reduces wiring harness complexity and weight, while maintaining a secure, sealed interface suitable for harsh environments.
