IP68/69K sealing is the cornerstone of the UTS78E4PW's reliability in harsh environments. This plastic jam-nut receptacle keeps water, dust, and oil out, protecting sensitive solder joints and extending mean time between failures. In production lines and outdoor equipment, that level of ingress protection translates directly into lower maintenance costs and reduced unplanned downtime. Gold-plated solder cup contacts provide robust electrical performance under vibration and temperature cycling. Rated for 7 A and 32 V, the connector supports reliable low-voltage DC control circuits and powering of sensors without excessive contact resistance. Engineers can spec this part with confidence for control cabinets and mobile machinery where space and reliability matter. The 1/3 bayonet coupling paired with jam-nut receptacle architecture delivers fast, repeatable mating without tools in many layouts. That reduces installation time and ensures consistent sealing, even in cramped enclosures. The W-keying orientation supports correct polarity and reduces mis-wiring in complex harnesses. Operating from -40 °C to 105 °C and with UV resistance and chemical compatibility with mineral oil, gasoline, and basic/acid baths help ensure long-term performance. It also withstands salt spray for corrosion resilience and supports vibration tests up to 2000 Hz per IEC 60512-4. With 250 mating cycles and a rugged neoprene insert, the part delivers lifecycle efficiency and predictable performance. The compact shell size 8 and 4-position layout support dense harnessing in small enclosures while maintaining ease of maintenance.

FAQs
The UTS78E4PW is a jam-nut receptacle designed for panel or enclosure mounting without a backshell. Use the aluminum nut to secure the housing and ensure correct W orientation for mating. It accepts 4 solder cup contacts and is supplied without a backshell, which must be ordered separately. Plan for Neoprene insert compatibility and verify space for the 25.3 mm length and 24 mm width/height.
This connector provides a 7 A current rating with a test current of 7 A CSA and supports a 32 V IEC / 250 V CSA / 250 V UL test voltage. It features 4 contacts with gold plating and solder cup contact type, suitable for low-voltage control circuits in rugged environments. Operating temperature ranges from -40 °C to 105 °C.
Yes. The UTS78E4PW carries IP68 sealing (and 69K in unmated conditions) and UV resistance with basic and acid/base bath durability, making it suitable for outdoor automation, mobile equipment, and industrial machinery. Its rugged construction, vibration resistance, and UV stability help reduce maintenance and replacement costs in challenging sites.
The connector meets UL 1977, IEC 61984, and CSA-C22.2 No.182.3 certifications. It also carries RoHS exemptions (6.c), supporting compliance in regulated industries. These certifications address electrical safety, performance under typical automation conditions, and environmental compliance for OEM installations.
With 250 mating cycles and gold-plated contacts, the UTS78E4PW provides reliable repeated connections with low contact resistance. Its IP68/69K seal and robust materials minimize corrosion and ingress ingress, reducing maintenance frequency. The compact 4-contact layout improves harness density, lowering installation time and downstream field service costs.
