Contact SINOCONNECTORS

Please provide the part number, required quantity and application whenever possible. Drawings, datasheets, photos, electrical requirements, environmental conditions and mating-interface information can help us evaluate the requirement more accurately. If you do not know the exact model, simply describe the application.

Yes. You can send photos, markings, drawings, datasheets, an existing manufacturer part number or information about the mating connector. Clear images of the mating face, rear termination and product markings are especially useful for initial identification.

Yes. Replacement projects can be evaluated using the existing part number, mating interface, dimensions, contact arrangement, mounting method, electrical performance and environmental requirements. Similar appearance alone is not sufficient to confirm compatibility.

You do not need to know the exact series before contacting us. Tell us the application, contact count, current, voltage, signal type, operating environment, installation method, space limitations and any available dimensions. We can use this information to narrow down suitable product families.

Yes. You can upload drawings, datasheets, BOM files, pin maps, connector photos and other technical specifications through the inquiry form. These documents are strongly recommended for custom, replacement and cable-assembly projects.

Yes. Customization can be evaluated for contact arrangement, insert layout, shell structure, materials, surface treatment, mounting, termination, PCB interface, cable integration, mixed power and signal, high-current, high-voltage, high-speed and environmental requirements.

Yes. A complete assembly can integrate connectors, contacts, cable, pin assignment, shielding, rear accessories, strain relief, sealing, labeling and testing. Fiber-optic and optical-electrical hybrid assemblies can also be evaluated for suitable applications.

Yes. Our referenced product portfolio includes waterproof, pressure-resistant, corrosion-resistant, wet-mate and subsea interconnect directions. Please provide the water exposure or target depth, pressure, cable type, mating requirement, material requirement and environmental conditions.

Yes. High-current and high-voltage connector and cable-harness requirements can be evaluated. Final contact size, insulation, cable construction, thermal performance and safety margin should be selected according to the actual voltage, current and operating conditions.

Selected connector families support high-speed differential, coaxial / RF, data-bus and optical technologies. Please provide the required data rate, frequency, impedance, cable or PCB architecture and communication protocol when known.

Yes. The same inquiry form can be used for cooling fans, centrifugal blowers, motors, actuators and related industrial products. For fans, provide voltage, dimensions, airflow, static pressure and environment. For motors, provide voltage, speed, torque, duty cycle and control requirements.

If your project has mandatory qualification or acceptance requirements, specify them in the inquiry. Relevant tests may include electrical performance, insulation, dielectric withstand, contact resistance, mating life, vibration, shock, temperature, humidity, salt spray, waterproofing, pressure, EMI or signal performance.

Prototype or sample support can be evaluated according to the selected product and project. Custom projects may proceed through requirement review, engineering evaluation, prototype or sample preparation, validation and production stages.

Yes. You can contact SinoConnectors through WhatsApp at +86 153 3081 0685 for product questions, photos, drawings and initial project communication. For detailed RFQs containing multiple technical files, email or the website inquiry form is recommended.

Please send RFQs and technical inquiries to [email protected]. When possible, include the part number, project name or inquiry type in the email subject so the requirement can be reviewed more efficiently.
