FAQs
Without a backshell, ensure proper jam-nut tightening to compress the sealing interface and seat the primary O-ring. Align the connector squarely to prevent mis-mating, and use compatible strain relief if the cable run experiences movement. IP68 protection relies on correct sealing and cable ingress protection at the junction; verify mating faces are clean and fully seated before engage.
Yes, this is a PCB-contact receptacle designed for surface or through-hole mounting with four gold-plated socket contacts. It supports 7 A per IEC/UL, 32 V per multiple standards, and provides 250 mating cycles. The connector is oriented for W mounting and delivers a loaded contact delivery suitable for compact control panels and sensor interfaces.
Ideal for rugged automation panels, outdoor equipment, motor drives, and sensor networks, the UTS78D4SW32 combines IP68/69K sealing with a compact jam-nut receptacle footprint. Its 4-contact PCB configuration suits signal and moderate power needs in harsh environments, delivering reliable connectivity in wash-down zones and high-vibration machinery.
Certified to UL 1977, CSA-C22.2 No.182.3, and IEC 61984, the UTS78D4SW32 meets global safety and performance standards for inline connectors. RoHS and REACH compliance further ensure material restrictions and environmental responsibility, important for regulated industries and multinational deployments across automotive, food, and industrial equipment sectors.
With 250 mating cycles and robust ingress protection, maintenance intervals can be extended in comparison to lower-rated interfaces, reducing downtime. The gold-plated contacts preserve signal integrity, while the compact footprint lowers panel space and installation costs. Over the product life, users benefit from reliable operation in demanding environments and lower replacement frequency.
