Quick Summary

The Eaton UTS78E3PW is a plastic waterproof connector designed for rugged industrial automation and outdoor equipment. Users often struggle with ingress, unreliable contacts, and compatibility issues in dusty or wet environments. It delivers IP68/69K protection with RoHS-compliant materials and UL/CSA certifications, helping you meet safety, reliability, and regulatory requirements. In manufacturing and field service, you gain reliable mating and easier installation with a 1/3 bayonet coupling, improving uptime and field efficiency. The 3-contact design uses gold-plated solder cups for secure, low-resistance connections, even under vibration. With a neoprene insert and compact jam-nut receptacle, installation remains straightforward and resistant to oil, UV exposure, and environmental stress.

IP68/IP69K protection paired with a 3-pin solder cup configuration keeps ingress at bay and reduces field maintenance, translating to higher uptime and lower service costs in washdown zones and dusty outdoor environments. Application: rugged sensors, actuators, and control modules in harsh exposure zones. The 7 A current rating and up to 250 V support compact, reliable power and signal paths, minimizing connector count in control panels and remote I/O subsystems. Application: small to mid-power devices where space and reliability matter. Mating cycles at 250 ensure long life in maintenance-heavy environments, reducing replacement cycles and total cost of ownership. Application: frequent field servicing, machinery with modular wiring, and equipment undergoing regular diagnostics. Gold-plated contacts provide low contact resistance and corrosion resistance, preserving signal integrity in vibration-prone installations. Application: precision sensors and communication lines in mobile equipment. UV, oil, and salt spray resistance extend service life in outdoor and industrial settings, lowering spare-part demand. Application: outdoor substations, construction sites, and marine environments. Compliance with RoHS exemption 6.c, IEC 61984, UL 1977, and CSA-C22.2 No.182.3 simplifies regulatory clearance and supplier qualification. Application: certified equipment deployments and tender-ready projects. Compatibility with the UTS series and W-keyed design supports straightforward integration into existing harnesses and assemblies, while the 1/3 Bayonet coupling enables fast, secure mating in tight spaces. Application: field installations where quick connector engagement is essential.

FAQs

The UTS78E3PW uses a 1/3 bayonet coupling for quick engagement. To install, align the receptacle with the mating plug, rotate to lock, and secure with the jam nut. Ensure the neoprene insert seats properly to maintain IP68/69K protection. Use the correct W-keying to avoid mis-mating and verify that the backshell is ordered separately if required by your harness.
The connector is rated for 7 A per IEC and 7 A per UL, with test voltages of up to 250 V (CSA/UL) and up to 32 V (IEC). It supports 3 contacts in a solder cup configuration, with gold plating for reliable, low-resistance connections across up to 250 mating cycles, making it suitable for frequent maintenance scenarios.
Yes. It is IP68-rated (and IP69K in unmated conditions), UV resistant, and engineered to withstand oil, acid and mineral oil exposure, with a salt spray tolerance of 500 hours. Its -40 to 105 °C operating range makes it appropriate for outdoor and industrial installations subject to wide temperature swings and washdowns.
The UTS78E3PW complies with RoHS exemption 6.c, IEC 61984, CSA-C22.2 No.182.3, and UL 1977. These certifications aid in regulatory clearance, safety compliance, and procurement qualification for machinery and control systems used in global markets.
Low-maintenance durability (250 mating cycles), robust environmental resistance, and reliable contact plating reduce replacement frequency and field service time. The combination of IP68/69K protection and regulatory compliance lowers downtime, assembly costs, and warranty exposure, delivering a favorable ROI in tough industrial deployments.
