IP68/69k protection combined with a jam-nut receptacle delivers reliable sealing in outdoor and washdown environments, reducing maintenance cycles and preventing moisture ingress, which translates to lower downtime and longer equipment life. The 3-pin PCB contact configuration with gold plating enhances electrical reliability and signal integrity, enabling stable operation for sensors and small actuators while supporting a compact PCB footprint in control panels. A 1/3 bayonet coupling provides quick, vibration-tolerant mating, improving installation speed and field serviceability in tight enclosures. The 7 A current rating and 32 V/250 V voltage compatibility offer flexible power and control options, enabling multi-application use without swapping connectors. Rugged shells, Neoprene insert material, and an aluminium nut ensure corrosion resistance and lightweight handling for cost-effective scalability. Compliance with UL, IEC, RoHS, and CSA standards simplifies procurement and certification across global projects, while a 25.3 mm length and 24 mm width/height support space-constrained assemblies. The absence of a backshell option reduces cost and simplifies maintenance in environments where space and weight matter. Designed for 250 mating cycles, the UTS78D3PW meets operational reliability targets for automation panels and field deployments, even under frequent connection-disconnection scenarios. Field engineers gain confidence in a connector that balances mechanical resilience with electrical performance, minimizing both risk and total cost of ownership.

FAQs
The UTS78D3PW uses a jam-nut receptacle without a backshell, simplifying panel mounting in tight spaces. Its IP68 rating ensures water and dust sealing in submerged or washdown areas, while its 3 PCB contacts and gold plating support reliable electrical connections. Use appropriate panel cutouts and torque the nut to specification to preserve ingress protection during maintenance or reassembly.
It is rated for 7 A and supports voltages up to 32 V for IEC and 250 V for UL/CSA applications. The connector delivers three PCB contacts with gold plating, designed for reliable signal and power transfer in automated systems. This combination enables safe operation of sensors and actuators within the specified voltage and current limits.
Yes. The connector provides a PCB contact configuration with 3 cavities, keying W, and a 1/3 bayonet coupling for secure mating. The jam-nut receptacle is intended for panel mounting, and the compact 25.3 mm length with 24 mm width/height supports densely packed control panels. With gold-plated PCB contacts, it ensures low contact resistance over many mating cycles.
It complies with UL 1977, IEC 61984, RoHS exemption 6.c, and CSA-C22.2 No.182.3. These certifications support safety, interoperability, and environmental compliance in global deployments, simplifying procurement and approval processes for automotive, industrial, and automation projects.
The UTS78D3PW supports up to 250 mating cycles and withstands operating temperatures from -40 °C to 105 °C. It provides resistance to gasoline, oils, and UV exposure, and its aluminum nut, plastic shell, and neoprene insert offer corrosion resistance and durable field use in harsh environments.
