The UTS78E98PX features IP68/IP69K sealing with a jam-nut receptacle, delivering dust-free, water-protected connections that minimize field failures and maintenance costs in outdoor and rugged applications, such as mining or marine equipment. This translates to tangible uptime gains and lower total cost of ownership as assemblies withstand exposure to moisture, oils, and UV radiation while preserving signal integrity. The 3-pin solder cup contacts are gold-plated for low contact resistance and corrosion resistance, supporting stable performance in harsh environments and long-term reliability for sensor and actuator wiring. With a 1/3 bayonet coupling and a mating cycle rating of 250, technicians experience faster, more secure installations and fewer re-works in production lines. The operating range from -40 °C to 105 °C covers extreme field conditions, while the Neoprene insert and plastic shell keep the assembly lightweight yet robust, enabling easier handling and compatibility with Souriau UTS series accessories. This design also addresses common objections about field-serviceability by offering a simple, tool-friendly mating process and a backshell-free configuration that reduces inventory and installation steps. Typical applications include automated machinery, outdoor control panels, and rugged sensing networks, where sustained vibration resistance and chemical resilience are critical for performance and safety.

FAQs
The UTS78E98PX is a jam-nut receptacle from the UTS series designed for 3-pin solder cup contacts with a 1/3 bayonet coupling. It requires a mating plug from the same series and does not include a backshell by default, so order the appropriate connector accessory separately. Orientation is X, and ensure the space allows 25.3 mm length, 24 mm width, and 24 mm height for proper clearance.
The connector provides a 7 A current rating (UL, IEC) and supports up to 250 V. It is IP68-rated (water and dust ingress protection) and operates from -40 °C to 105 °C. It uses gold-plated solder cup contacts and supports 250 mating cycles, with a Neoprene insert and plastic shell for durability.
It complies with IEC 61984 and UL 1977, with CSA-C22.2 No. 182.3 support, and benefits from RoHS exemption 6.c. These certifications help ensure suitability for regulated industrial environments and safer procurement decisions.
Its jam-nut receptacle design and 1/3 bayonet coupling provide secure, vibration-resistant mating. The IP68 rating, UV resistance, and a robust 250 mating cycles specification help ensure long-term reliability in outdoor and vibration-prone applications, while the Neoprene insert and sealed housing minimize ingress and environmental impact.
With 250 mating cycles and a 500-hour salt spray rating, the UTS78E98PX is built for moderate-to-heavy use in harsh environments. Routine inspection of the mating interface and seals is recommended, and consider stocking a compatible backshell accessory if additional shielding or cable management is required to prolong life and maintain signal integrity.
