IP68/69K protection provides reliable ingress resistance in washdown and outdoor environments, helping reduce leaks and downtime while enabling continuous production. This translates to lower maintenance costs and greater line uptime for food processing, outdoor OEMs and process automation. The 3 PCB contacts with gold plating deliver strong signal integrity and corrosion resistance, improving long term reliability in control panels and sensor interfaces, even in challenging climates. The jam nut receptacle with no backshell option allows compact and secure panel mounting, quick field service and reduced hardware inventory, which accelerates installation in tight spaces. A 7 A current rating supports common control circuits without oversizing harnesses, while the 25.3 mm length and 24 mm by 24 mm shell footprint suit compact automation enclosures. The UTS design's ultrasonic UV resistance and wide operating temperature range from -40 C to 105 C ensure dependable operation in extreme environments, minimizing unplanned downtime. With 250 mating cycles, the connector is built for repetitive maintenance cycles common in machine upgrades and retrofit projects. The neoprene insert adds ground sealing and vibration damping, reinforcing performance in high vibration applications such as conveyors and packaging lines. The plastic shell keeps weight down and aids in cost control for high-volume panel builds, while the 1/3 bayonet coupling simplifies engagement and disconnection during field installation or service, reducing labor time and the risk of improper mating.

FAQs
The UTS78D3S32 uses a jam nut receptacle design for panel mounting without a backshell. Ensure a compatible panel hole and JAM NUT thread fit, then tighten the jam nut to seal against ingress. The 25.3 mm length and 24 mm square shell footprint fit standard compact enclosures, while the 1/3 bayonet coupling enables quick mating. Confirm that panel cutouts accommodate the 8 shell size and the neoprene insert to maintain IP68 protection during service.
The connector is rated for 7 A current with voltage ratings of up to 250 V (UL/CSA) and 32 V (IEC). For most industrial logic and control circuits, design the harness to stay within the 7 A limit per contact, and ensure compliant wiring practices in accordance with IEC 61984 and UL 1977 guidelines to maintain safe operation and regulatory compliance.
Yes. The UTS78D3S32 provides IP68 protection in unmated conditions and is designed for harsh environments, including UV exposure and mineral oil resistance. Its neoprene insert adds sealing performance, while the plastic shell keeps weight down and supports rugged outdoor or washdown machinery applications such as packaging lines, outdoor automation and marine equipment.
The unit references IEC 61984, UL 1977, CSA C22.2 No. 182.3, and ROHS exemption 6.c. Compliance with these standards supports safe operation in automated equipment, assures regulatory alignment for electrical safety and environmental rules, and facilitates procurement for certified machinery builds and retrofit projects in regulated industries.
With 250 mating cycles and robust chemical and vibration resistance, the UTS78D3S32 reduces replacement frequency and field service time. The IP68/69K seal and gold plated PCB contacts minimize corrosion and signal loss, lowering warranty claims and maintenance costs. In retrofit projects, quick mating and reliable performance shorten downtime during upgrades, delivering faster project ROI.
