FAQs
The UTS78D4P32 uses a jam nut receptacle with hold-down clips and does not require a backshell. It supports a four-contact PCB configuration, a 25.3 mm depth, and a 24x24 mm footprint. Orientation is fixed as N, and the 1/3 bayonet coupling enables straightforward, secure mating within compact panels. This setup simplifies panel integration and reduces mounting time on new or retrofit projects.
The connector provides a 7 A current rating (UL/IEC) and supports up to 250 V (UL/CSA) with a 32 V rating per IEC. It uses four gold-plated PCB contacts and is designed for 250 mating cycles. These specs support reliable power and signal transfer in demanding automation and control applications while maintaining contact integrity over repeats.
Yes. It carries IP68 protection and IP69K capability in unmated conditions, which is ideal for outdoor enclosures and equipment exposed to dust, water spray, or washdowns. The assembly includes UV-resistant materials, salt spray resistance for up to 500 hours, and a temperature range from -40 °C to 105 °C, ensuring long-term performance in harsh climates.
The UTS78D4P32 complies with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with RoHS exemption 6.c. This alignment supports global regulatory compliance in many industries, assists with supplier audits, and reduces redesign requirements when integrating into certified assemblies or systems in automation, robotics, and industrial equipment.
Gold-plated PCB contacts enhance corrosion resistance and signal integrity, delivering repeatable mating and lower contact resistance over time. With 250 mating cycles and a robust 7 A/250 V capability, you gain higher reliability, reduced maintenance intervals, and lower lifecycle costs in sensor networks, motors interfaces, and distributed I/O where frequent connections are expected.
