IP68/69K sealing and environmental resistance provide robust protection against moisture, dust, oil, and UV exposure, significantly reducing field failures and warranty costs in wet production lines and outdoor installations. This translates to higher line availability and lower maintenance labor for robotics and conveyors that operate in harsh environments. With a 7 A current rating and 250 V capability, the UTS78E33PW supports reliable control circuits and sensor networks without overdesign, improving system efficiency and safeguarding equipment life in automation cabinets and field enclosures. The 3-pin solder cup contacts with gold plating deliver durable, low-resistance connections, extending service life and minimizing contact wear in high-cycle applications such as packaging and pick-and-place systems. The 1/3 bayonet coupling and jam-nut receptacle design enable quick, secure mating even in cramped panels, reducing installation time and potential misalignment during maintenance. Operating from −40 °C to 105 °C, this connector tolerates extreme temperatures common in outdoor machinery and industrial sites, improving uptime and component compatibility across regional deployments. Insert material neoprene and shell plastic deliver corrosion resistance and weatherproofing while keeping weight and cost low, making it ideal for light-industrial equipment, open-frame controls, and rugged sensor networks. Salt spray resistance for up to 500 hours further extends outdoor viability, supporting long service intervals in maritime or agricultural environments. RoHS exemption 6.c ensures compliance without compromising performance in global supply chains.

FAQs
The UTS78E33PW uses a jam-nut receptacle configuration with W orientation; a backshell is not included and must be ordered separately. It accepts 3 male solder contacts and is designed to pair with the UTS series via a 1/3 bayonet coupling for quick, secure mating. For a complete panel installation, consider the compatible UTS accessories and mounting hardware to ensure a tight seal and alignment in constrained spaces.
Electrical ratings include a 7 A current rating for IEC and UL, and 250 V maximum voltage (CSA rated as 250 V, with separate IEC 50 V). The 3-contact solder cup design supports stable connections, and the unit is specified for up to 250 mating cycles. Gold-plated contacts enhance corrosion resistance, enabling reliable operation in demanding automation environments while meeting UL, IEC, and CSA safety standards.
Yes. The UTS78E33PW is engineered for harsh outdoor and industrial use with IP68 sealing, oil and gasoline resistance, UV stability, and salt spray tolerance of up to 500 hours. It operates from −40 °C to 105 °C and resists vibrations (per IEC 60512-4). This makes it well suited for robotics, conveyors, and open-air equipment exposed to weather, oils, and environmental stress.
The connector complies with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with RoHS exemption 6.c. These certifications support global regulatory alignment, supplier qualification, and regional product approvals, helping streamline procurement and ensure consistent performance across markets without duplicating part variants.
The sealed IP68 protection, UV and oil resistance, and a long service life up to 250 mating cycles reduce field maintenance and downtime. Gold-plated contacts improve longevity in corrosive environments, while the compact jam-nut design speeds installation. Overall, this translates to lower total cost of ownership, faster repair cycles, and higher uptime for automated systems in tough industrial settings.
