FAQs
The UTS78E3PM12 is designed as a threaded receptacle without a backshell, which simplifies panel cutouts and reduces bulk. If backshell protection is required for strain relief or EMI shielding, plan to source a compatible accessory separately. Ensure adequate clearance for the 21.3 mm length and fitment within the 24x24 mm footprint while maintaining ingress protection integrity.
This receptacle supports a 7 A current rating with a 250 V capability per UL/CSA standards and operates from -40 °C to 105 °C. These ratings make it suitable for typical automation loads, motor sensors, and control circuits in industrial environments without compromising safety or performance.
Industries with exposure to moisture, oils, or outdoor conditions benefit most, including outdoor control panels, mining and construction equipment, agricultural machinery, and rugged automation systems. Its compact form and 3-pin solder contacts simplify harness design for space-constrained enclosures while maintaining core sealing and reliability requirements.
The connector complies with UL 1977, CSA-C22.2 No.182.3, and IEC 61984, with RoHS exemption 6.c. These certifications support safety, interoperability, and environmental compliance in many regions, helping you meet procurement specifications and regulatory requirements for industrial equipment and automation projects.
With 250 mating cycles, UV and oil resistance, and robust IP68 sealing, the UTS78E3PM12 offers predictable lifecycle performance and reduced maintenance. For field deployments, plan for periodic inspection of contacts and seals, ensure correct mating alignment, and keep the backshell option in mind if additional mechanical protection is needed.
