Eaton UTS78D98SW Receptacle - IP68/69K Waterproof
Part Number: UTS78D98SW
Quick Summary
Eaton UTS78D98SW Receptacle is a plastic waterproof connector for rugged PCB-to-cable interfaces in industrial gear. Engineers face ingress protection challenges and field failures when tough environments expose connectors to moisture, dust, and vibration. This device delivers robust protection with IP68/69K sealing, UL 1977 and IEC 61984 compliance, and ROHS exemption 6.c, helping you meet stringent standards while simplifying assembly. By using a jam-nut receptacle with a W-keyed orientation and 3 PCB contact sockets, you gain reliable mating and predictable service life. Integrating this component can reduce maintenance costs, boost uptime, and improve equipment reliability in harsh environments.

FAQs
Begin by aligning the W-keyed orientation and mate the 3 PCB contacts with the corresponding pads. Tighten the jam nut to secure the receptacle against the panel, ensuring the IP68 seal remains intact. No backshell is required, simplifying space-constrained installations and reducing assembly time.
The UTS78D98SW carries UL 1977 and IEC 61984 compliances, and it meets ROHS exemption 6.c. It provides IP68 sealing (up to unmated condition) and a robust environmental profile suitable for harsh industrial environments.
Yes. The operating temperature range is -40 °C to 105 °C, enabling reliable performance in mechanical enclosures exposed to wide ambient temperatures without thermal degradation of materials or contacts.
The connector is rated for 7 A (IEC/UL/CSA) and supports up to 250 V (CSA/UL) with 3 contacts for PCB connectivity. The contacts are gold-plated for durability, and the layout accommodates three cavities for robust signal/power distribution.
With 250 mating cycles and a resistant material set (plastic shell, neoprene insert), expect long service life in challenging environments. Plan for periodic inspection of the sealing interface and verify polarity and mateability after extended exposure to vibrations or contaminants.
