Eaton UTS78D4P Receptacle - IP68/69K Waterproof
Part Number: UTS78D4P
Quick Summary
Eaton UTS78D4P is a plastic waterproof IP68/69K receptacle designed for rugged industrial automation connections. In wet, oily, or washdown environments, connectors frequently fail from moisture ingress and corrosion. It aligns with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with RoHS exemption 6.c, helping you meet regulatory requirements while improving reliability. This 4-pin PCB receptacle uses a compact jam-nut design without a backshell, enabling tight panel fit. With gold-plated contacts, 1/3 bayonet coupling, and a tough plastic shell, it delivers stable power and signal delivery for sensors, controllers, and field devices, reducing downtime and maintenance costs in harsh environments.

IP68/69K sealing provides robust ingress protection against water, dust, and washdown environments, increasing uptime for process automation lines and outdoor equipment. This translates to lower maintenance cycles and fewer field failures when used on sensors and actuators in challenging facilities. The 1/3 bayonet coupling enables fast mating and disassembly, significantly reducing installation and service time on robotics and packaging lines. Four gold-plated PCB contacts offer reliable electrical performance with excellent corrosion resistance, supporting precise sensor data transmission and steady control signals for PLCs and embedded systems. The jam nut receptacle design (no backshell) minimizes footprint in tight panels, streamlining cabinet layouts and reducing harness complexity, while demanding proper cable management and strain relief for EMI considerations. Operating from -40 °C to 105 °C with durable environmental resistance, including oil and UV tolerance, this connector supports outdoor and harsh-industrial deployments with long service life and predictable maintenance schedules. At 7 A current rating and up to 250 mating cycles, it balances performance and durability for continuously switching sensors, small actuators, and field devices, delivering reliable operation with minimal replacement costs.
