FAQs

The UTS78D33S32 uses a jam-nut receptacle design without a backshell, providing a compact, secure mount. Align the PCB contacts to your board, thread the jam nut onto the port, and tighten to specification to ensure a watertight seal. This approach minimizes assembly steps while maximizing sealing performance in IP68-rated environments.
This receptacle is rated for 7 A current and supports up to 250 V across UL, IEC, and CSA standards. Such ratings make it suitable for typical automation and control circuits, allowing reliable operation in damp or washdown environments without overdesign.
Yes. It is IP68 rated for protection against water ingress and is UV resistant, with materials selected to withstand prolonged exposure without degradation. It also demonstrates resistance to oils and fuels, making it appropriate for outdoor machinery and harsh industrial settings.
The connector aligns with UL 1977, CSA-C22.2 No.182.3, and IEC 61984 standards, along with RoHS exemptions. These certifications help ensure electrical safety, compatibility with industrial panels, and environmental compliance in global projects.
The UTS78D33S32 supports up to 250 mating cycles, providing a predictable service life for frequent connect/disconnect scenarios. Its 3-contact PCB arrangement and robust sealing reduce maintenance frequency and support uptime themes in automated systems.
