FAQs
The UTS78E4PWM12 is a threaded receptacle with four solder cup contacts and a W orientation. For proper performance in challenging environments, ensure a secure mating with the 1/3 bayonet coupling, use appropriate sealing procedures, and respect the operating temperature range of -40 °C to 105 °C. This helps maintain IP68/IP69K protection during installation and service.
This connector is rated for 7 A current (IEC/UL/CSA) and supports a voltage of 32 V (IEC) or 250 V (UL/CSA). It features four contacts with solder cup termination and a 250 mating cycle life, making it suitable for frequent connect/disconnect cycles in automation and control panels.
Yes. The IP68/69K rating, plus UV resistance and resistance to oils and minor chemical baths, makes it well-suited for outdoor robotics and washdown environments. Its neoprene insert and plastic shell provide durability, while the 4‑pin configuration supports compact power and signal distribution in mobile or field-installed systems.
The connector complies with IEC 61984, UL 1977, and CSA-C22.2 No.182.3, with ROHS exemption 6.c. This regulatory alignment helps ensure compatibility with safety and performance requirements across global automation projects and equipment.
With 250 mating cycles, sealed IP68/69K performance, and a compact design, maintenance intervals can be extended and downtime reduced. The no-backshell option and quick-mating features streamline installation and servicing, lowering labor costs and the need for additional protective accessories over the system’s lifecycle.
