A circular connector is a coupling device built with a circular interface and cylindrical contact housing which comes with a huge variety of materials, sizes, contact layouts & types, and coupling designs. These circular connectors are commonly utilized for data, signal and power connections in the automation, manufacturing, military, aerospace and transit industries thanks to their rugged mechanical performance and ease of connectivity. They are also very versatile & flexible because of a wide range of contacts, voltages, and currents that can be conveniently featured based on the requirements of the applications.

Mencom is the leading manufacturer of circular connectors and their rugged solutions are engineered for reliable performance under the most extreme use in harsh environments. Mencom offers a complete line of circular connectors, including but not limited to, M8, M12, 1/2”-20 and M23 threads and MINI-Change connectors (MIN) with 7/8", 1”, 1 1/8” threads. For the higher voltage (600V) applications, Power Distribution PMIN series with 1” 3/8 thread is also available. According to their recent product announcement, the coupling nuts and housings of the cordsets for 1” and 1 1/8” threads have recently been redesigned to deliver the better connectivity and stability. In addition to the power and signal connectors, Mencom offers M12 and 7/8” threads circular connectors for the industrial Network solutions such as DeviceNet, Ethernet, Foundation Fieldbus, Profibus, and Profinet.

Due to the numerous advantages of the circular connectors, it comes as no surprise that the military has developed the MIL-Spec 5015 series to meet the most stringent requirements to endure the toughest environments. Although the MIL-Spec 5015 circular connectors were originally designed for aeronautical and tactical service applications, they are becoming more commonplace in industrial applications that need the ruggedness of the MIL-Spec design, but do not need the military specifications. In order to meet the strong demand from various industries, Mencom has designed and offers a MIL-Spec 5015 Equivalent connector series with size 10SL (0.625”-24NEF), 14S (0.875”-20UNEF), 16S (1”-20UNEF) and 18(1.125”-18UNEF).

Mencom circular connectors are UL listed and IP67 rated to provide the utmost protection and quality for harsh environments. Multiple pole configurations and cable jacket materials including PVC, PUR and TPR are available for over-molded connectors along with a full line of accessories such as field wireable plugs, T-connectors, closure caps and plugs to name a few. Mencom has the largest variety of mounting styles for the mating circular receptacles.  Also, all the circular connectors are customizable upon request with fast turnaround at affordable costs. The range of the customization is from small changes to custom terminations and assemblies. Rugged armor options for extreme manufacturing environments are available for 7/8”, M12 and M8 circular connectors. Please click HERE for more details.
