Waterproof sealing is a foundational feature that reduces ingress risk in washdown environments, resulting in fewer field failures and lower warranty costs; ideal for food processing, packaging lines, and outdoor automation. The 3-pin PCB contact arrangement with gold plating delivers low contact resistance and long-term signal integrity, translating to higher uptime for sensors and control circuits in rugged settings. Jam Nut Receptacle with hold-down clips provides secure panel mounting and precise alignment without a backshell, simplifying installation in compact enclosures and enabling reliable cable routing. The 1/3 Bayonet coupling delivers quick mating with strong retention, minimizing downtime during maintenance and panel swaps. Operating from -40 °C to 105 °C and rated at 7 A, it supports high-temperature environments and dependable power delivery for small actuators and controllers. Rugged environmental resistance covers gasoline, oil, mineral oil, and UV exposure, ensuring sustained performance in industrial zones and outdoor applications. Mating cycles of 250 indicate durable life under frequent connect/disconnect cycles, reducing replacement costs and downtime. The resin shell and aluminum nut keep weight and size manageable for panel-integrated solutions, while the no backshell option concentrates sealing and strain relief into the receptacle body, requiring thoughtful enclosure design and cable management for optimal reliability. In practice, the combination of IP68 rating, robust mechanical retention, and compact footprint makes this connector a strong match for inline machines, automation modules, and field-deployed sensors, where reliability and fit are as critical as electrical performance.

FAQs
The UTS78D3APW32 is a jam nut receptacle designed for panel mounting with hold-down clips and no backshell. Install by securing the jam nut from the exterior, align the 3-pin PCB contacts to the board, and solder the pins while ensuring the mating orientation is W. This simplifies installation in compact enclosures and maintains IP68 sealing without additional backshell components.
This connector provides a 7 A current rating and 250 V maximum voltage per channel, with gold-plated PCB contacts to ensure low contact resistance and long-term corrosion resistance. It is designed for 3 contacts, 3 cavities, and 250 mating cycles, making it suitable for intermittent to frequent connect/disconnect scenarios in automation equipment.
Yes. The IP68 rating ensures ingress protection in water, dust, and immersion scenarios, while environmental resistance covers gasoline, oil, mineral oil, and UV exposure. The operating temperature range from -40 °C to 105 °C supports outdoor and harsh indoor environments typical of industrial automation and outdoor machinery.
The product complies with CSA-C22.2 No.182.3, IEC 61984, and UL 1977, with ROHS exemption 6.c. These certifications help verify safety, performance, and environmental compliance across North American and international markets.
With 250 mating cycles and gold-plated contacts, the UTS78D3APW32 offers durable life with minimal maintenance. The no backshell option can reduce part count and potential sealing leaks; plan enclosure design to maintain IP68 integrity. Its lightweight (7.2 g) and compact footprint support faster assembly, lower device weight, and reduced field downtime, delivering favorable total cost of ownership in automated systems.
