IP68/69K sealing provides reliable ingress protection in wash-down and outdoor environments, reducing maintenance cycles and ensuring uptime in harsh conditions. This translates to lower total cost of ownership for equipment exposed to moisture, dust, and vibration, ideal for industrial automation and outdoor machinery that require durable connectors. The 2-pin PCB contact arrangement with gold plating delivers consistent electrical performance and corrosion resistance, preserving signal integrity in demanding control systems and robotics applications. The jam-nut receptacle with no backshell option simplifies installation in tight panels while maintaining IP ratings, minimizing enclosure modifications and saving assembly time for field technicians. The 1/3 bayonet coupling enables quick mating and unmating, improving serviceability during preventive maintenance and field upgrades. With a compact shell (plastic, 8 mm shell size) and neoprene insert, the unit is lightweight yet robust, suitable for space-constrained control panels in packaging lines and automated equipment. Compatibility with UL 1977 and IEC 61984 standards ensures compliance across North American and European projects, while the RoHS exemption 6.c support helps meet environmental obligations. The product also withstands wide operating temperatures (-40 °C to 105 °C) and a broad vibration spectrum (10 to 2000 Hz), supporting reliability in automotive, material handling, and process automation systems. Its 250 mating cycles and 2 cavities align with typical lifecycle expectations for maintenance-intensive installations, enabling predictable maintenance planning and ROI improvements. The absence of a backshell option reduces options to consider during procurement, simplifying sourcing for standard 2-contact silicone-free interfaces. The combination of IP68/69K, high mating cycles, and compact footprint makes UTS78D2P a preferred choice for critical PCB-to-cable interface points in rugged industrial environments.

FAQs
The UTS78D2P is specified as a jam nut receptacle with no backshell option. If a backshell is required, a different part number or connector family from the Souriau/Uts series should be selected to maintain IP68/69K integrity and proper cable strain relief.
The connector provides a 7 A current rating (UL/IEC) and 250 mating cycles. It carries a voltage rating up to 250 V (CSA/UL) and 32 V (IEC). With gold-plated PCB contacts and a 2-contact configuration, it maintains reliable electrical performance in demanding control circuits and monitoring systems.
Ideal for rugged automation, packaging lines, outdoor machinery, and process equipment, especially where IP68/69K sealing, vibration resistance, and space-constrained PCB-to-mount connectivity are critical. The 1/3 bayonet coupling and jam-nut receptacle design simplify panel integration in harsh environments.
This model aligns with UL 1977, IEC 61984, RoHS exemption 6.c, and CSA-C22.2 No.182.3. It also satisfies IP68 sealing, UL94 HB flammability, and operational resilience across -40 to 105 °C, making it suitable for global installations and regulated industries.
With 250 mating cycles and a robust plastic shell with neoprene insert, the connector supports predictable maintenance intervals and reduced downtime. The no-backshell design minimizes parts and installation steps, while gold-plated contacts help sustain performance, lowering replacement and servicing costs over the equipment lifecycle.
