Protection and sealing deliver uptime in demanding settings. The UTS78E3P provides IP68 sealing with unmated conditions and a rugged 3 cavity layout, preventing contaminants from reaching critical circuits and enabling reliable operation in mobile equipment. This reduces unplanned downtime and lowers maintenance costs over the product lifecycle. Electrical performance translates to lower operating expenses: a 7 A rating and multi-standard compatibility (UL, CSA, and IEC) support safe, efficient power delivery and simplify compliance reporting across regions. The solder cup contacts are gold-plated for dependable signal quality and corrosion resistance, while a compact 25.3 mm depth supports tight panel integrations in confined enclosures. Durable materials, including a plastic shell, aluminium nut, and neoprene insert, deliver a robust enclosure that withstands UV exposure, temperature swings, and vibration. Installation is straightforward thanks to a jam-nut receptacle design and a 1/3 bayonet coupling, which lowers field labor time and error rates. Compatibility with the Souriau UTS series provides a familiar, modular path for spares, reducing total cost of ownership while enabling scalable automation deployments. The product’s ruggedness—-including resistance to salt spray and wide operating temperature range—helps customers plan for long service life in demanding applications such as outdoor machinery, agricultural equipment, and mobile industrial gear. In short, the UTS78E3P blends protection, performance, and ease of use to support reliable automation projects and cost-effective maintenance strategies.

FAQs
The UTS78E3P is a jam-nut receptacle designed for 3-pin solder-cup contacts and 1/3 bayonet coupling. It fits standard Souriau UTS mating hardware, with a compatible backnut (not supplied) and no backshell by default. For installation, ensure correct panel cutout, align orientation N, and secure with the jam nut to achieve IP68 sealing. Note backshells and accessories must be ordered separately.
The connector provides 3 contact positions with gold-plated solder-cup contacts. It supports a 7 A current rating and up to 250 V test voltage (UL 250 V, CSA), with 32 V IEC. This enables reliable power and signal transfer in demanding environments while maintaining safe operating margins.
Ideal for rugged automation, outdoor equipment, mobile machinery, and agricultural or marine applications, the UTS78E3P combines IP68/IP69K sealing, 3-cavity configuration, and bayonet coupling to resist water ingress, vibrations, and environmental exposure while enabling quick field assembly.
The UTS78E3P aligns with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with RoHS exemption 6.c and REACH considerations. These certifications support regulatory compliance across regions and help facilitate safe integration into certified equipment and systems.
With a mating cycle rating of 250 and durable materials (neoprene insert, UV resistance, salt spray tolerance), the connector offers long service life and reduced replacement cycles. Its compact form and straightforward QC-friendly installation reduce field labor time, contributing to lower total cost of ownership in demanding environments.
