IP68/69K protection of the UTS78E2SM12 minimizes ingress when unmated, ensuring plug-and-play reliability in outdoor enclosures and mobile equipment. The rugged plastic shell, combined with a neoprene insert, resists mineral oil, fuels, and UV exposure, reducing field failure rates and warranty costs. With a 7 A current rating and test voltage up to 250 V, this 2-contact solder-cup receptacle supports essential machine wiring without oversized hardware. The 32 V IEC rating per contact and UL/CSA compatibility enable safe control circuits while maintaining a compact footprint. Its small footprint—21.3 mm length, 24 mm width and height, 7.2 g weight—fits tight panel gaps and lightweight assemblies. The 1/3 bayonet coupling and threaded receptacle design provide robust engagement, while no backshell option reduces parts and simplifies installation. Mating cycles are 250, and operating temperature spans -40 to 105 C, with UV resistance and chemical resistance ratings. The Neoprene insert maintains seal integrity through repeated mating, supporting long service life in demanding environments. Designed for Souriau UTS family compatibility, the 2-position, socket female contacts integrate with standard harnesses for industrial machinery, outdoor equipment, and outdoor field deployments, delivering a compact, sealed wiring solution that lowers maintenance costs and downtime.

FAQs
Install the UTS78E2SM12 as a threaded receptacle with the socket contacts and Neoprene insert seated properly. Since there is no backshell option, ensure the mating connector provides adequate strain relief and sealing at the connection interface. Use appropriate cable preparation and secure mounting to maintain IP68 protection in unmated and mated states.
The connector supports a 7 A current rating with a 32 V IEC and 250 V UL/CSA voltage range. It uses two solder cup contacts, comes as a loaded receptacle, and has a 21.3 mm length with 24 mm width and height. This configuration suits compact control circuits and lightweight harnesses across industrial equipment.
Yes. It carries IP68/69K protection for unmated and mated conditions, operates from -40 °C to 105 °C, and provides UV resistance with mineral oil and fuel resistance. Its 250 mating cycles and Neoprene insert further ensure reliability in vibration-heavy, oil-exposed, and outdoor installations found in mining and field equipment.
The connector aligns with UL 1977 and IEC 61984 for industrial connectors, plus CSA-C22.2 No.182.3. It also carries RoHS exemption 6.c. These certifications support safe selection, wiring practices, and compliance within industrial automation and electrical installations.
With 250 mating cycles and robust sealing, the UTS78E2SM12 reduces maintenance frequency and field failures, lowering downtime and service costs. Its compact footprint and no backshell design simplify installation, enabling faster harness assembly and easier replacements, delivering lower total cost of ownership for OEMs and service teams.
