Circular Connector Cable Assembly Builds
M8 and M12 circular connector assemblies for industrial equipment, sensors, panels, and machine networks.
MiniProto builds circular connector cable assemblies using HARTING, TE, Phoenix Contact, M8, and M12 options. We help teams choose shielding, coding, pin count, straight or right-angle exits, panel-mount transitions, and field-wireable connectors for prototype and low-volume builds.
Why MiniProto
Professional Harnesses Without The Wait
M8 And M12 Coverage
Build compact M8 sensor leads, standard M12 cordsets, panel transitions, and custom circular connector pigtails.
Coding And Shield Review
We check A-code, B-code, D-code, pin count, shielding, drain wire, and mating requirements before manufacturing.
Quote-Ready Custom Builds
M8 and M12 combinations vary widely, so custom circular assemblies go through quote review for the right connector and cable.
Technical Specifications
Circular Connector Overview
Common M8 and M12 circular connector choices for industrial cable assemblies.
| Family | Coding | Pins | Typical Use |
|---|---|---|---|
| M8 | A-Code | 3 or 4 | Compact sensors and actuators |
| M12 | A-Code | 3, 4, 5, 8, 12 | Sensors, actuators, IO, power-limited circuits |
| M12 | B-Code | 4 or 5 | Fieldbus and legacy automation networks |
| M12 | D-Code | 4 | Industrial Ethernet to 100Mb |
| Panel Mount | By family | By connector | Cabinet and machine bulkhead transitions |
| Field-Wireable | A, B, D | By connector | Serviceable machine wiring and prototypes |
Shielding, jacket material, and IP rating depend on the chosen connector and cable construction.

Popular Preconfigured Builds
Start From A Reviewed Configuration
Use these catalog builds as a starting point, or send a drawing when the assembly needs connector, pinout, or routing review.
Custom Circular Builds Go Through Quote Review
M8 and M12 combinations depend on coding, pin count, gender, shielding, panel style, and cable jacket. Send your BOM or pinout and we will quote the correct assembly.
Applications
Built Around Real Installations
Industrial sensors and actuators
Machine Ethernet and fieldbus wiring
Panel-mount circular connector transitions
Prototype equipment cable sets
Process
From Requirements To Tested Harnesses
Define The Connector
Share M8 or M12 family, coding, pin count, gender, exit style, and cable length.
Review Cable Needs
We confirm shielding, jacket, conductor count, field-wireable requirements, and panel details.
Build And Verify
Assemblies are terminated, labeled, continuity checked, and packaged for the machine or panel.
