Feature → Business Impact → Application: IP68 rated sealing and UV/oil resistant materials protect against water ingress, extend service life in washdown and outdoor environments, and reduce maintenance costs for factory automation lines. This translates to fewer unplanned shutdowns and lower total cost of ownership in food processing, packaging, and water treatment equipment. Feature → Business Impact → Application: 7 A current and 250 V rating paired with gold-plated PCB contacts provides stable signal and power transfer for sensor networks and control loops, improving reliability and reducing failure-related downtime in process automation and motor control panels. Feature → Business Impact → Application: 1/3 Bayonet coupling enables rapid, tool-free mating in tight spaces, increasing installation efficiency on assembly lines and field service van calls, while ensuring robust vibration resistance in heavy industry. Feature → Business Impact → Application: 3-position, jam-nut receptacle with 3 female PCB contacts supports compact PCB integration, enabling thinner enclosures and easier thermal management in compact control cabinets and panel boards. Feature → Business Impact → Application: Operating temperature range from -40 °C to 105 °C and salt spray resistance deliver consistent performance in extreme environments, reducing the risk of thermal drift and corrosion-related faults in outdoor machinery and industrial automation gear. Feature → Business Impact → Application: Neoprene insert and aluminium nut provide durable, corrosion-resistant hardware compatible with common Souriau UTS accessories, enabling straightforward retrofit and scalable panel designs for evolving automation needs. Feature → Business Impact → Application: 25.3 mm length and 24 mm wide footprint with 8 shell size streamline layout planning, supporting compact PCB layouts and easier integration with existing harnesses and cabling schemes in aerospace-adjacent or rugged industrial applications. Each benefit is supported by field-tested materials and consistent performance data to help procurement teams justify the total cost and lifecycle advantages of selecting the UTS78D3ASW32 in new projects.

FAQs
The UTS78D3ASW32 is a jam nut receptacle designed for panel-mount PCB integration. Install the three gold-plated female PCB contacts, align the W orientation, and thread the jam nut to secure the connector without a backshell. Ensure the panel cutout accommodates a 25.3 mm depth and 24 x 24 mm footprint for a snug, sealed fit, then engage the 1/3 Bayonet coupling for secure mating.
This receptacle provides a 7 A current rating and 250 V test voltage, with 3 contact positions in a PCB-contact configuration. Contacts are gold-plated for reliable signal transfer, and the unit ships with loaded contact delivery for immediate usability in assembled PCBs.
Yes. The connector features IP68 sealing and IEC/UL/CSA compliance, with resistance to UV, oils, acids, mineral oils, and gasoline. It is engineered for exposed environments and supports operation from -40 °C to 105 °C, making it well-suited for washdown areas, outdoor machinery, and rugged automation panels.
The UTS78D3ASW32 aligns with UL 1977, CSA-C22.2 No.182.3, and IEC 61984 standards, with ROHS exemption 6.c. These certifications ensure electrical safety, cross-industry interoperability, and compliance with environmental regulations, reducing risk during procurement and integration in regulated industries.
Mating cycles are rated at 250, supporting durable service in automation panels. The gold-plated PCB contacts resist corrosion, and the hardware uses aluminium nut components for sturdy mechanical retention. With a salt spray rating of 500 hours and robust environmental resistance, maintenance intervals can be extended, lowering total cost of ownership in long-life installations.
