FAQs
Install the jam-nut receptacle from the exterior, align with the X-keying, and thread the nut to the panel. The design is backshell-free, which reduces accessory parts and simplifies the mounting process. Ensure a clean grommeted cutout and proper torque on the jam nut to maintain IP68/69K sealing integrity.
The UTS78D3APX adheres to UL 1977, CSA-C22.2 No.182.3, and IEC 61984, with ROHS exemption 6.c. These certifications support safety, compatibility with industrial controls, and global sourcing requirements for equipment used in regulated environments.
Yes. The 1/3 Bayonet coupling, IP68 sealing, and robust shell design provide strong vibration resistance. With 250 mating cycles and gold-plated PCB contacts, the connector maintains electrical integrity and mechanical reliability in dynamic installations.
The UTS78D3APX is rated for 7 A and 250 V, with an operating range from -40 °C to 105 °C. This makes it suitable for most standard automation and control circuits while tolerating extreme ambient conditions.
Its jam-nut, no-backshell design, and compact footprint reduce hardware requirements and installation time. Gold-plated PCB contacts offer durable performance, lowering maintenance frequency, while the 250 mating cycles support long-term lifecycle stability in rugged environments.
