Share what you know so we can review your assembly requirements together.
You can begin with the information available today. Drawings, specifications, sample photos, and connector details help us understand what needs to be made.
Drawings and specifications
Send any available drawing or specification with your inquiry. Useful details include the drawing revision, planned quantity, connector manufacturer and part numbers, wire specifications, lengths and tolerances, pinout, and any special inspection requirements. You do not need every detail settled for a first inquiry.
Reference samples
If you have a sample, send photos and your requirements first. Please contact Shengxin before shipping it. Sample disassembly and drawing preparation can be discussed; we will confirm permission to disassemble the sample and arrangements for its return before shipment.
