Circular Metric Connectors
EI Sales connects OEMs to high-quality circular metric connectors from trusted manufacturing partners. We help engineers source rugged, sealed interconnects for tight-space applications in automation, medical, and transportation systems. Our team works closely during design and selection to match coding options, contact styles, and ingress ratings to the demands of each build.
Circular Connector Types We Offer
We supply a full range of circular metric connectors, including threaded, bayonet, and push-pull styles. These connectors are built to perform in environments where space is limited, sealing is required, and reliability is non-negotiable.
M5 Connectors
Ideal for compact sensors and control devices where every millimeter counts. M5 connectors are used in miniature automation and tight PCB layouts.
M8 Connectors
A common choice for signal and low-power applications in factory automation. Available in multiple coding options and IP-rated versions.
M12 Connectors
Highly versatile for signal, data, and power. M12 connectors are offered in A-code, B-code, D-code, and X-code for Ethernet, power, and I/O needs.
M16 Connectors
Suited for medium-power transmission and more robust signal connections. Often found in field equipment and instrumentation.
M23 Connectors
Designed for high-current and mixed-signal use. These larger circular connectors are preferred for motors, actuators, and fieldbus systems.
7/8" Connectors
Typically used in power applications for industrial automation. Compatible with rugged wiring systems in demanding installations.
Push-Pull Connectors
Quick-connect locking for medical and instrumentation devices. Allows secure mating without threading in compact enclosures.
Bayonet Locking Styles
Fast, tactile locking that holds firm under vibration. Ideal for transportation and field-mounted equipment.
A-Code, B-Code, D-Code, X-Code Options
Coding options that prevent mis-mating and support specific protocols like Ethernet, power distribution, and signal routing.
Custom Overmolded Cable Assemblies
Custom assemblies available with molded strain relief, color-coded wiring, and sealing for harsh environments.
BNC Connectors
Common in test and measurement setups. BNC offers secure coaxial connections for analog and RF signal paths.
IP67 HDMI Connectors
Sealed HDMI solutions for displays and video equipment exposed to dust, moisture, or industrial washdowns.
M5 Connectors
Ideal for compact sensors and control devices where every millimeter counts. M5 connectors are used in miniature automation and tight PCB layouts.

Get the Right Connector Fast
Speed matters when you're up against project deadlines. EI Sales helps engineering and sourcing teams move quickly through connector selection by coordinating directly with manufacturers and application engineers. We clarify specs early, identify compatible part numbers, and align environmental ratings to your system requirements.
For builds that need a fast turnaround, we work with partners that offer flexible tooling, stocked components, and prototyping support. Our goal is to help you avoid design revisions and keep production schedules moving.
Built for Rugged Industrial and Harsh Environments
EI Sales sources connector solutions that perform in tough conditions such as moisture, vibration, dust, or fluctuating temperatures. The connectors we source are tested for ingress protection, shielding, and long-term durability in the field.
We help engineering teams align connector specs with environmental and mechanical needs, including IP-rated sealing, locking mechanisms, and material selection. Whether the application involves mobile equipment or factory control systems, we can match the right interconnect to the job.
