IP68/69K sealing and rugged enclosure design deliver industry-grade protection for PCB connections exposed to water, dust, and mineral oils. This reduces unwarranted downtime and field servicing in outdoor equipment, robotic arms, and mobile machines where ingress protection is non-negotiable. The unmated IP rating, combined with UV resistance and salt spray tolerance, ensures long-term reliability in harsh environments. Three PCB contacts with gold plating offer stable signal integrity for sensors, actuators, and data lines. The gold contact finish minimizes contact resistance and corrosion, extending service life in vibration-heavy machinery and compact panel layouts. The jam-nut receptacle with aluminium nut and 1/3 bayonet coupling enables quick mating without backshell accessories, reducing hardware and inventory needs while withstanding routine vibration. Electrical ratings of 7 A and voltages up to 32 V IEC or 250 V CSA/UL make it suitable for common automation circuits, and the operating range from -40 to 105 °C supports outdoor and mobile installations. Finally, the neoprene insert and plastic shell, along with 250 mating cycles and 500-hour salt spray resistance, deliver a durable lifecycle for OEM deployments and field service teams.

FAQs
The UTS78D3S uses a jam-nut receptacle with an aluminium nut and 1/3 bayonet coupling, designed for unmated IP68/69K protection. It is a three-contact PCB socket supplied without a backshell, enabling direct panel or harness integration. It remains compatible with standard Souriau accessories, supporting space-constrained installations and predictable field servicing with secure, vibration-resistant mating.
The connector provides three PCB contacts in a socket (female) configuration, delivered loaded. Contacts are gold-plated to minimize contact resistance and corrosion, ensuring reliable signal integrity for sensors and controllers in harsh environments. This configuration supports robust PCB-level connections in automation equipment and mobile machinery.
UTS78D3S carries a current rating of 7 A (UL and IEC) with a test current of 7 A (UL/CSA/IEC) and voltage ratings of 32 V (IEC) and 250 V (CSA/UL). It operates across a temperature range from -40 °C to 105 °C and supports 250 mating cycles, making it suitable for steady automation and control circuits in demanding environments.
Yes. It offers IP68 protection in unmated conditions, resistance to oils and other contaminants, UV stability, and a salt-spray tolerance of 500 hours. With a 1/3 bayonet coupling and 250 mating cycles, the design keeps mating reliability under vibration. This makes it appropriate for outdoor equipment, conveyors, and mobile machinery operating in challenging sites.
The UTS78D3S complies with IEC 61984, CSA-C22.2 No. 182.3, UL 1977, and RoHS exemption 6.c. These certifications support global safety, environmental, and regulatory requirements, easing design-in for multinational deployments and helping meet industry-standard procurement and quality criteria.
