FAQs
Begin by aligning the 24 mm width and 24 mm height receptacle with the enclosure cutout, insert the jam-nut, and torque to spec to seal against dust and moisture. Ensure the PCB contacts are loaded and mate the connector with the corresponding plug using the 1/3 bayonet coupling for secure, vibration-resistant connection. No backshell is required, but plan enclosure protection to maintain IP68 integrity.
The connector supports a 7 A current rating and accepts voltages up to 32 V IEC and 250 V UL/CSA. It provides 4 contacts with gold plating for reliable PCB connections, and offers 250 mating cycles. Operating temperature spans from -40 °C to 105 °C, making it suitable for demanding industrial applications.
Yes. The unit features UV resistance and IP68 protection, ensuring continued performance in outdoor or exposed applications. Its environmental sealing and resistant materials reduce degradation from oils, fuels, and fluids typical in industrial settings, helping to maintain long-term reliability.
The UTS78D4S complies with IEC 61984, UL 1977, and CSA-C22.2 No.182.3 standards, along with RoHS exemption 6.c. These certifications support safe, compliant use in many industrial systems and help simplify supplier qualification and regulatory adherence.
With 250 mating cycles, gold-plated PCB contacts, and robust IP68 sealing, the UTS78D4S reduces maintenance frequency and the risk of moisture-related failures. The compact jam-nut receptacle and lack of a backshell lower upfront accessory costs, while delivering durable, long-life connectivity in harsh environments.
