IP68/69K protection and 7 A current rating deliver robust ingress protection and reliable power delivery in dirty, wet, or dusty environments, reducing maintenance downtime and warranty exposure in continuous-operation applications. The 3 solder-cup contacts with gold plating ensure low contact resistance and corrosion resistance, improving signal integrity and extending lifecycle in harsh industrial settings. The 1/3 bayonet coupling enables quick, tool-free mating and demating, accelerating installation and field service while minimizing assembly errors. Jam Nut Receptacle mounting provides a secure, vibration-resistant interface suitable for panel or enclosure integration in mobile equipment and outdoors. Neoprene insert and plastic shell balance chemical resistance, UV durability, and cost-effective mass production for automotive and automation projects. Mating cycles of 250 support reliable repetitive connections, decreasing replacement costs over time.

FAQs
To install, select the jam-nut receptacle and align the 1/3 bayonet coupling with the corresponding male interface, then twist to engage until fully seated. Use the LED-free, solder-cup contacts to connect conductors and verify a secure, watertight seal. Compatibility considerations include ensuring the mating insert is the correct layout (33) and that the accessory options are ordered separately if required for your panel thickness or environmental enclosure. Confirm voltage and current ratings match your application (50–250 V, up to 7 A) to maintain safe operation and certification compliance.
Key specs include 3 gold-plated solder-cup contacts with a 7 A current rating, operating voltage from 50 to 250 V, and IP68 protection (unmated). It features a 1/3 bayonet coupling for quick mating and a jam-nut receptacle design for secure mounting. The contact arrangement supports a layout of 33 with 3 cavities, and the mating cycle rating is 250 cycles, ensuring durability in recurring assembly and maintenance events.
Yes. The UTS78E33SW is designed for rugged environments, offering IP68/69K ingress protection, UV resistance, and operation from -40 °C to 105 °C. Its plastic shell with neoprene insert provides chemical and vibration resistance, while gold-plated solder contacts ensure reliable signaling in automated systems. The 7 A rating accommodates most control circuits, and the compact jam-nut receptacle form factor simplifies mounting in automotive, outdoor machinery, and field robotics.
The connector complies with CSA-C22.2 No.182.3, UL 1977, IEC 61984, and ROHS exemption 6.c, supporting safety, interoperability, and environmental requirements. Its IP68/69K rating provides ingress protection suitable for unmated conditions, and the product is designed for robust performance in industrial automation settings. Always verify the exact certification scope for your region or customer standards when procuring.
Plan for lifecycle maintenance by leveraging the 250 mating cycles specification, which supports frequent assembly/disassembly without premature wear. The gold plating and sealed design help minimize contact resistance over time, reducing maintenance intervals. Consider stocking the recommended mating accessories separately to preserve the integrity of the IP seal, and schedule periodic inspections for the neoprene insert and plastic shell to confirm continued resistance to UV exposure and harsh chemicals in outdoor deployments.
