IP68/69K sealing and rugged plastic shell deliver reliable ingress protection, significantly reducing the risk of water-related faults in wet or dusty environments. This translates to lower maintenance costs and less unplanned downtime on manufacturing lines and outdoor installations. 4 gold-plated PCB contacts offer low contact resistance and durable performance under vibration, improving signal integrity and extending component life in demanding applications. The 1/3 bayonet coupling enables quick, tool-free mating and un-mating, accelerating assembly and service workflows while maintaining a secure connection in vibration-prone settings. The jam nut receptacle design eliminates the need for a separate backshell, reducing weight, cost, and assembly complexity in panel and enclosure installations. Operating from -40 °C to 105 °C supports temperature extremes common in outdoor and industrial sites, ensuring stable operation across shifting conditions. With 250 mating cycles, technicians can rely on consistent performance through recurring maintenance or component swaps without premature wear. Neoprene insert and plastic shell provide chemical and UV resistance, supporting long service life in harsh environments such as outdoor machinery, conveyors, and robotics. Compliance and material choices align with RoHS exemptions and industry standards, boosting supplier confidence and simplifying qualification for regulated environments.

FAQs

Install the jam nut receptacle through the panel cutout with the mating side oriented as specified (W). Tighten the jam nut to secure the connector, ensuring the IP68/69K seal remains intact. Note there is no backshell option for this variant, which simplifies installation but requires careful routing and strain relief at the harness entry.
The UTS78D4PW provides a 7 A current rating (UL and IEC) with test voltages of up to 250 V CSA and UL ratings, 32 V IEC. It features 4 gold-plated PCB contacts and supports mating cycles up to 250, making it suitable for repeated field maintenance without significant wear.
Yes. With IP68 sealing and a rugged plastic shell, the UTS78D4PW is designed for wet, dusty, and outdoor environments. The 4-pin PCB arrangement and gold-plated contacts maintain signal integrity, while the neoprene insert provides a resilient seal against moisture intrusion around the mating interface.
The connector carries IEC 61984, UL 1977, and CSA-C22.2 No.182.3 certifications, along with ROHS exemptions. These certifications support global compliance for industrial equipment and simplify procurement and qualification processes for regulated applications, reducing risk when integrating into compliant systems.
The IP68/69K sealing, 250 mating cycles, and gold-plated PCB contacts provide durable, low-resistance connections that resist ingress and wear. Quick mating via 1/3 bayonet coupling minimizes service time, while the jam nut receptacle design reduces mounting complexity and parts count, delivering lower total cost of ownership over the product lifecycle.
