How We Work With Different Sourcing Needs

Buyers reach us at different stages. Here is how we usually support standard sourcing, custom projects, and OEM supply.

Standard

Standard Sourcing
Custom

Project-Based Customisation
OEM

OEM & Recurring Supply
What buyers are solving Replacing an existing product, matching a known spec, or finding a reliable second source. Building an assembly with specific length, connector type, or insulation that standard items do not cover. Integrating a cable assembly into a manufactured product with consistent quality and recurring supply.
What QSNTECH can confirm Connector compatibility, insulation equivalence, current ratings, and available colour options. Configuration feasibility, material suitability, MOQ, and realistic lead time expectations. Tooling options, packaging and labelling customisation, quality documents, and export awareness.
What helps quotation move faster A product photo, part number, or datasheet, plus quantity and target delivery region. A drawing, sample photo, or written description, plus quantity and application environment. A confirmed drawing or approved sample, annual volume estimate, and target market requirements.
Preparing Your RFQ

What to Send for a Faster Technical Response

The more context you include in your first message, the quicker we can confirm feasibility and provide an accurate quotation.

Information Item Why It Helps Accepted Format
Drawing or Diagram Confirms connector layout, dimensions, and assembly structure before sampling begins. PDF, DXF, CAD export, or hand sketch photo
Product Photo Often the fastest way to identify connector style and match to an existing product family. JPG, PNG, or phone photo
Connector Type Helps identify whether the request belongs in plugs, clips, probes, panel sockets, or mixed-end assemblies. Text description, photo, or part number
Cable Length Important for evaluating stock options versus custom assembly discussion. mm, cm, m, or inches — approximate is fine
Insulation Preference PVC, silicone, or TPE changes temperature rating, flexibility, and cost direction. Text note, or we can recommend based on application
Quantity Determines whether the request is sample stage, short-run batch, or structured supply discussion. Pieces per order or estimated annual volume
Target Market Helps identify relevant compliance expectations such as CE, RoHS, or UL awareness. Country or region name
Application Notes Voltage, current, temperature, or end-use context leads to a more suitable recommendation. Short text description — no formal format needed

You do not need all of this before reaching out. A photo and a quantity is often enough to begin a useful conversation. Send what you have →
