FAQs
The UTS78E2PWM12 uses a threaded receptacle with no backshell option and a 1/3 bayonet coupling for quick, secure mating. It supports 2-pin solder cup contacts, W orientation, and is designed for straightforward harnessing in compact spaces. For field retrofit, verify cavity count and mating orientation before installation to ensure reliable engagement and seal integrity.
This connector is rated for 7 A (UL/IEC) with test voltages of 32 V (IEC) and 250 V (UL/CSA). It is IP68-rated and resistant to oils, UV exposure, and broad temperature ranges (-40 °C to 105 °C), making it suitable for outdoor automation, sensors, and rugged equipment deployed in harsh environments.
Yes. The IP68/69K sealing, UV and oil resistance, and rugged plastic shell make it well-suited for outdoor and marine automation, where moisture, dust, and chemical exposure are common. Its compact size, bayonet coupling, and two-pin solder contacts support reliable field connections in space-constrained installations.
The connector complies with IEC 61984 and UL 1977, with CSA-C22.2 No.182.3 recognition, and is RoHS exempt 6.c. These certifications provide safety, interchangeability, and environmental compliance across multiple markets, ensuring reliable performance in automation and field applications.
With up to 250 mating cycles and robust ingress protection, maintenance intervals can be extended and downtime reduced. The no-backshell design lowers weight and installation costs, while wide operating temperature and oil/UV resistance support longer service life in demanding environments, delivering measurable ROI through lower total cost of ownership.
