Why Choose AC Threaded

The AC Threaded series is designed for customers who need a threaded cylindrical connector that can adapt to a variety of industrial requirements without sacrificing durability. Its broad configuration range helps simplify product development by giving engineers multiple shell styles, contact layouts, and termination methods within one proven family. This makes AC Threaded a strong choice for OEMs looking to standardize around a connector platform that can support multiple power and signal needs.

Another advantage of AC Threaded is its ability to serve across both general-duty and more demanding operating environments. The combination of aluminum shells, threaded coupling, environmental options, and IP67 protection helps support reliable performance where equipment may be exposed to vibration, contaminants, or challenging installation conditions. For industrial equipment builders, that means a connector solution that supports both application flexibility and field durability.

AC Threaded Applications

AC Threaded can be used across a range of industrial and commercial applications where a threaded cylindrical connector is needed for robust electrical interconnection. Its configuration flexibility makes it suitable for equipment requiring mixed power and signal contacts, while its range of shell styles supports different mounting and cable routing requirements. Applications may include industrial machinery, power systems, heavy-duty equipment, control systems, and other environments where dependable circular connector performance is important.

Because the series supports power-only, signal-only, and mixed arrangements, AC Threaded can help engineers reduce connector family complexity while maintaining a familiar and proven interface style. This flexibility is valuable in designs where long product life, serviceability, and dependable field performance are key priorities.

Design Flexibility for Industrial Connectivity

AC Threaded supports a wide design window for engineers specifying a threaded cylindrical connector. Available wall receptacles, cable receptacles, box receptacles, straight plugs, and right-angle plugs give design teams flexibility during enclosure and harness development. Support for solder and crimp contacts, along with available thermocouple and coax contact options, makes the series adaptable for varied electrical requirements.

This flexibility is especially valuable when a single connector family must support multiple equipment variants or future design changes. By combining proven cylindrical connector architecture with broad configuration options, AC Threaded helps reduce complexity while maintaining a durable and familiar interconnect format for industrial programs.
