FAQs

Installation is straightforward: mount the jam nut receptacle, align the 1/3 bayonet coupling, and mate the 3-contact PCB socket with compatible Souriau UTS series components. The unit supports standard Souriau UTS series accessories, but note that no backshell option is available for this variant. Ensure correct orientation (W) during assembly to preserve IP68 sealing.
This connector is rated for 7 A per UL and IEC standards, with a test voltage of up to 250 V (UL/CSA) and a mating cycle life of roughly 250 cycles. These specs support reliable low-to-medium power signal and control applications in demanding environments, aligning with typical industrial automation requirements.
Yes. The UTS78D33SW32 features IP68 sealing and UV resistance, plus resistance to mineral oil and gasoline, making it well-suited for washdown zones, outdoor equipment, and exposed industrial installations. Its neoprene insert and jam nut receptacle design enhance ingress protection while maintaining robust mechanical integrity under vibration.
The connector complies with UL 1977, IEC 61984, and CSA-C22.2 No.182.3, with additional RoHS exemption 6.c. These certifications support safe use in control panels, machinery, and systems requiring recognized electrical interfaces, helping meet electrical safety and environmental standards across North American and international deployments.
The combination of IP68/69K protection, gold-plated contacts, and 3-contact PCB receptacle reduces ingress-related failures and contact resistance, lowering maintenance cycles and downtime. The quick-mate 1/3 bayonet coupling simplifies field servicing, while compatibility with the Souriau UTS family streamlines procurement, potentially reducing total cost of ownership over the product lifecycle.
