The IP68/69K sealing provides a robust barrier against moisture and dust, reducing field failures and maintenance costs while enabling reliable performance in outdoor panels and mobile machinery. The three gold-plated PCB contacts deliver durable signal integrity and corrosion resistance, supporting long-term reliability of control signals in industrial networks. A 1/3 bayonet coupling offers quick mating and secure retention, cutting installation time and training needs for field technicians. Operating temperatures from -40 °C to 105 °C, UV resistance, and chemical耐ance extend service life in harsh environments, minimizing unexpected downtime. A 7 A current rating with a 250 V limit covers typical automation circuits, while 250 mating cycles ensure durable, repeated connections for robotics and process lines. The compact footprint (25.3 mm length, 24 × 24 mm) and jam nut receptacle design save panel space and simplify sourcing, though note there is no backshell option for this model.

FAQs
UTS78D98S is a jam nut receptacle designed for direct panel mounting and ships without a backshell. It uses a 1/3 bayonet coupling and a fixed orientation (N), with three PCB contacts loaded in the receptacle. If a backshell is required, select a compatible accessory from the Souriau UTS family or contact us for options.
The unit provides three PCB contacts with gold plating, rated for 7 A (UL/IEC) and up to 250 V, with a loaded contact delivery. It supports three cavities and three contact positions. The PCB-style contacts ensure reliable signal transfer and corrosion resistance suitable for automation networks.
Yes. It features IP68 sealing and UV resistance, designed to withstand moisture, oils, and grime. The operating temperature range is -40 °C to 105 °C, with resistance to mineral oil and gasoline exposure. This makes it suitable for automation panels, robotics, and mobile equipment operating in challenging environments.
The connector is rated for up to 250 mating cycles, supporting frequent connect and disconnect operations typical in maintenance, field service, and robotic applications, while maintaining reliable electrical performance throughout its life.
Best suited for control cabinets, robotics interfaces, and rugged field devices where a compact footprint, IP68 protection, and quick mating are valued. Its three PCB contacts and bayonet coupling help ensure secure, repeatable connections in tight spaces, with reliable performance in industrial automation environments.
