Circular & Heavy-Duty Connectors

About Circular & Heavy-Duty Connectors

Circular and heavy-duty connectors are the backbone of industrial, military, and harsh-environment electrical systems. From MIL-DTL-38999 aerospace connectors with bayonet coupling to M12 and M8 sensor-actuator interfaces on factory floors, these connectors must deliver reliable power and signal integrity under vibration, moisture, dust, and extreme temperatures. At icsourcedirect, we stock circular connectors across the full spectrum: MIL-DTL-38999 Series I/II/III from Amphenol and ITT Cannon, MIL-DTL-26482 bayonet connectors, M12 A/B/D/X/S/T-coded circulars from TE Connectivity and Phoenix Contact, M8 and M23 metric connectors, 7/8″ power connectors, and heavy-duty industrial rectangular connectors from Harting and Weidmüller. Key specifications buyers evaluate include pin count, shell size, coupling type (bayonet, threaded, or push-pull), IP rating (IP67 to IP69K), current rating, and contact gender. As an independent distributor based in Shenzhen, we source across brands without franchise restrictions — offering competitive lead times and pricing on short-run, allocated, and hard-to-find circular connector part numbers.
