FAQs
To install, align the PCB with the three contact cavities, slide the jam-nut receptacle into the panel cutout with the neoprene insert seated, then thread the jam-nut from the exterior to seal against the panel. Ensure the 1/3 bayonet coupling engages fully and the contacts are properly mated. The W orientation guides correct alignment for field wiring and sealing integrity, and mating cycles exceed typical maintenance intervals with 250 cycles.
The UTS78D3ASW supports a 7 A current rating per IEC and UL standards, with a test current of 7 A and a test voltage of 250 V (CSA/UL) and 50 V (IEC). It includes 3 gold-plated PCB contacts, a jam-nut receptacle configuration, and a 1/3 bayonet coupling, ensuring reliable low-resistance connections and safe operation across typical automation workloads.
Yes. The connector is rated IP68 for unmated and mated conditions, resistant to UV exposure, and has robust sealing against moisture ingress. It also offers salt spray resistance up to 500 hours and chemical resistance, making it well suited for outdoor control panels, outdoor machinery, and harsh industrial environments.
The UTS78D3ASW carries UL 1977 and IEC 61984 compliance, with RoHS exemption 6.c and CSA-C22.2 No.182.3 listed. These certifications support safety, interoperability, and regulatory alignment for North American and international industrial applications.
With a 7 A rating, 250 mating cycles, and IP68/69K sealing, this connector reduces maintenance downtime and field repair costs in harsh environments. Its long service life, UV/chemical resistance, and robust mating reliability translate to fewer panel rework events and lower replacement parts expense over device life cycles.
