FAQs
The UTS78D3PX32 uses a jam-nut receptacle mounted directly to the panel. The aluminium nut provides a secure, vibration-resistant seal, and the design allows for no backshell option. Use the X orientation and 3-position PCB contact arrangement to align with the PCB footprint, ensuring proper mating with the corresponding plug and reliable field performance.
Electrical performance includes a 7 A current rating (UL/IEC/CSA) and a maximum test voltage of 250 V UL/CSA and 32 V IEC. It features three gold-plated PCB contacts in a 3-cavity layout, with mating cycle capability up to 250 cycles. This combination supports robust signals in automation and instrumentation applications while maintaining safety margins.
Yes. It delivers IP68 protection (with IP69K unmated condition) and UV resistance, plus chemical durability against acids, bases, oils, and gasoline. It operates from -40 to 105 °C and withstands 500-hour salt spray exposure, making it suitable for washdown areas, outdoor enclosures, and challenging industrial settings.
The product aligns with UL 1977 and CSA-C22.2 No.182.3, along with RoHS exemption 6.c, and IEC 61984. These certifications support safe integration into safety-critical systems and regulatory compliance for industrial automation and electrical components.
With 250 mating cycles, corrosion and UV resistance, and a compact jam-nut mounting design, the UTS78D3PX32 reduces maintenance intervals and downtime.
