IP68/69K protection delivers proven sealing against moisture, dust, and washdowns, reducing field failures and maintenance cycles. This translates to lower downtime and longer service intervals in outdoor panels and wash-down environments. The three PCB contacts with gold plating provide reliable, corrosion-resistant electrical connections for critical control and sensing interfaces, improving first-pass mating reliability and reducing troubleshooting. The 1/3 bayonet coupling enables quick, secure mating even in tight spaces, speeding installation and service while reducing trainer time for technicians. Jam Nut Receptacle design with an aluminium nut offers rigid panel mounting and superior torque retention, while keeping inventory simple with no backshell option required. Operating temperature range from -40 °C to 105 °C accommodates extreme climates, and a 7 A rating with 250 mating cycles supports durable, long-life operation in demanding machinery. At 25.3 mm long, 24 mm wide and 24 mm high, the compact footprint fits dense panel layouts and minimizes enclosure intrusion, while neoprene insert material provides environmental sealing and UV resistance for extended field life. Together with RoHS exemption 6.c and IEC 61984 compliance, the unit supports compliant, cost-effective automation deployments with predictable maintenance and total cost of ownership.

FAQs
Yes, the unit is designed as a jam-nut receptacle tailored for panel mounting with a rigid aluminium nut. It features a 25.3 mm depth and a 24x24 mm footprint that fits common panel cutouts. Note that this model has no backshell option, so mounting relies on the jam-nut assembly and the keyed X orientation to ensure correct alignment and vibration resistance in harsh environments.
The UTS78D3APX32 provides a 7 A current rating with a 250 V test voltage (UL/CSA). It features 3 gold-plated PCB contacts and 250 mating cycles, ensuring reliable reuse. Operating temperature spans from -40 °C to 105 °C, with IP68 sealing. These specs support steady performance in temperature extremes and demanding industrial conditions.
Ideal for rugged automation, outdoor equipment, marine or coastal settings, and wash-down environments where moisture, dust, and vibration are concerns. The 3-pin PCB configuration suits sensor and control interfaces, while the IP68 rating and UV resistance of the insert material extend life in harsh outdoor installations and high-durability control panels.
This receptacle complies with UL 1977 and CSA-C22.2 No.182.3, with IEC 61984 compatibility and ROHS exemption 6.c. These certifications support safe use in North American and international automation projects, facilitate supplier qualification, and align with regulatory requirements for electrical components used in industrial equipment.
The combination of IP68 sealing, 250 mating cycles, and durable gold-plated contacts reduces field maintenance and replacement costs. A compact footprint simplifies panel design, while the 7 A rating supports robust loads. Overall, customers can expect lower downtime, easier serviceability, and a favorable total cost of ownership in harsh environments.
