Procurement Guide
Connector, cable and component procurement guide
This guide helps B2B buyers move from an application requirement to a manufacturable connector, cable assembly or component specification. Start with the electrical and mechanical conditions, then select the product family and confirm MOQ, testing, lead time and shipping.
What HBXINTAO supplies
Our catalogue currently covers more than 200 purchasable product lines across the categories below. Each product page shows the available variants, MOQ and wholesale quantity tiers; the full catalogue is available in the product listing.
- Connectors and adapters — XT30/XT60/XT90, EC3/EC5, DC power, USB/Type-C, terminal blocks, board-to-wire, audio and multi-pin connectors.
- Power, battery and charging connectors — e-bike, lithium-battery, high-current power, charging and conversion cables.
- Magnetic and pogo-pin connectors — 2-pin to multi-pin spring contacts, magnetic interfaces and related cable assemblies.
- Charging plugs and sockets — Type-C, Micro USB, DC barrel and waterproof panel-mount charging interfaces.
- Wires, cables and harnesses — silicone/PVC wire, battery and extension cables, custom harnesses and cable assemblies.
- Enameled copper wire — QA-1/155, 1UEW and 2UEW magnet wire in common diameters and roll weights.
- Switches, controllers and DC motors — switching and control components, brushed DC motors, gears and drive parts.
- Speakers and LED accessories — miniature speakers and modules, LED-strip connectors, adapters and related accessories.
Start with four questions
- What is the maximum continuous current? Do not use a short-duration peak as the design current.
- What are the system voltage and ambient conditions? High voltage requires adequate creepage and clearance; heat and vibration reduce the usable safety margin.
- What conductor and termination are required? The wire gauge must fit the connector, terminal and insulation system.
- How will the connection be used? Define mating cycles, disconnection frequency, bend radius, water exposure and keying requirements.
Product selection checkpoints
- Power and battery connectors: confirm rated current/voltage, contact size, housing, keying, polarity, cable gauge and expected mating cycles.
- Magnetic and pogo-pin connectors: confirm pin count, spacing, gender, current per contact, spring force, travel, alignment method and cable exit direction.
- Charging sockets: confirm the mating plug, panel opening, mounting method, ingress protection, current rating and required wire termination.
- Wires and cable assemblies: specify conductor construction, AWG, insulation, temperature rating, length tolerance, stripping, tinning, crimp/solder method and sleeve type.
- Enameled copper wire: confirm conductor diameter, copper weight, enamel grade, temperature class, solderability and roll or spool format.
- Switches and controllers: specify load type, voltage/current, operating force or actuation, circuit logic, panel cut-out and environmental protection.
- DC motors: confirm supply voltage, no-load and rated speed, torque, duty cycle, shaft dimensions, gear ratio and noise target.
- Speakers and LED accessories: confirm dimensions, impedance/power and cavity requirements for speakers; voltage, current, strip width and connector pitch for LED parts.

What to send for a quotation
- Product link or item number, mating connector series, pin count and gender
- Maximum continuous current and system voltage
- Wire gauge, insulation material and required length or tolerance
- Operating temperature, water exposure, vibration and mating-cycle requirements
- Order quantity, annual demand and required sample quantity
- Drawing, dimensioned photo or an existing sample
- Required electrical tests, acceptance criteria and packaging
- Destination country and postcode, so freight, taxes and duties can be calculated
MOQ, samples and wholesale pricing
Each product page displays the available MOQ and price tiers. Stock and custom items follow the same principle: a lower unit price applies as quantity increases. Trial and sample quantities are available for many product families, subject to specification and stock. For annual contracts or mixed-product orders, we can prepare a separate quotation and Proforma Invoice.
Quality and shipping
Orders are checked for quantity, dimensions, appearance and agreed electrical requirements before packing. We prepare export cartons, packing lists and commercial documents and ship worldwide by DHL, FedEx, UPS or air/sea freight according to the order size and destination.
Need help selecting a product?
Send the application, current, voltage, wire size, quantity and destination. We will recommend a listed product family or a practical custom assembly, then confirm price, MOQ, testing and lead time.

In-depth validation guides
- E-bike charging connector polarity and test checklist
- Pogo-pin contact resistance, spring force and mating-cycle validation
- Wire-harness testing and first-article inspection checklist
High-current battery connector reference
When the application needs a larger current path, inspect terminal design, contact resistance, keying, conductor size and thermal performance as one system.
