Frequently Asked Questions

Find quick answers about our circular & D-Sub connectors, cable assembly, MOQ, lead time, and technical support.

What circular connector types do you offer and how do I choose the right one?

We offer multiple circular connector options for industrial applications, with different pin counts, mechanical locking styles, and protection levels depending on the environment. To choose the right circular connector, we typically confirm your current/voltage, IP requirement (if needed), cable OD, shielding needs, and installation method. If you also require Cable Assembly, we can deliver a complete circular connector cable solution based on your application and wiring diagram.

What is your MOQ and lead time for cable assembly and connectors?

MOQ and lead time depend on the connector series and whether it’s a standard item or a custom cable assembly. For many standard circular connectors and D-Sub connectors, we can support small trial orders. For customized assemblies, MOQ is based on the BOM and tooling needs. We confirm the exact MOQ and production lead time after reviewing your specs, quantities, and approval of drawings/samples.

Do you provide samples and drawings?

Yes. We provide samples for evaluation (subject to availability and project needs) and can share technical documents such as datasheets, pin assignments, and 2D drawings for both circular connectors and D-Sub connectors. For custom projects, we can offer assembly drawings and confirmation documents before mass production, and NDA support is available if required.

Which D-Sub connector types do you manufacture (DB9/DB15/DB25/HD)?

We offer a full range of D-Sub connectors, including DB9, DB15, DB25, DB37, high-density (HD) types (such as HD15/HD26), Micro D Sub. Options typically include male/female, different termination styles (PCB, solder cup, crimp), and hardware choices for secure installation. If you also need Cable Assembly, we can supply complete D-sub cable assemblies with matched backshells and wiring.

How do connectors connect to a PCB?

Our PCB mount connectors, like M12 and d sub connectors, ensure a reliable connection with proper orientation.

Are connectors durable for harsh environments?

Yes, our connector design with ingress protection transmits signals in the harshest environments.

Do you offer custom cable assembly for circular and D-Sub connectors?

Yes. As a Cable Assembly manufacturer, we support custom cable assembly from prototype to mass production—including wire harnesses, overmolding, shielding, labeling, and connector-to-connector builds using circular connectors and D-Sub connectors. Share your wiring diagram or application requirements, and our engineering team will recommend the right materials, pinout, and assembly process.
