FAQs
The UTS78E4PM12 is specified without a backshell option. For proper protection, mount the receptacle in a suitable sealed enclosure and use compatible harnesses or cable assemblies that incorporate pre-sealed terminations. Ensure the mating plug is fully engaged to maintain IP68/69K integrity and verify the neoprene insert seating for correct sealing.
The connector lists IEC 61984, UL 1977, CSA-C22.2 No. 182.3, and ROHS exemptions. These certifications support safe operation in diverse markets, provide electrical and environmental compliance, and help meet global procurement standards for rugged automation systems and industrial equipment.
Yes. It specifies 250 mating cycles and employs a 1/3 bayonet coupled threaded receptacle design, delivering secure mating under vibration. The assembly is well-suited for high-vibration settings like packaging lines or mobile industrial machinery, reducing the risk of intermittent connections.
The device operates from -40 °C to 105 °C and provides a current rating of 7 A. This combination supports reliable performance in cold starts, hot plants, and moderate-power automation tasks, helping prevent thermal-related failures in harsh environments.
Key benefits include IP68/69K sealing for robust ingress protection, four solder-cup contacts for compact yet capable interfaces, and a durable 250-cycle life. These attributes translate to higher uptime, easier procurement with a compatible Souriau UTS family, and lower total cost of ownership in rugged automation applications.
