VG31 is built to VG 95234 with MIL-DTL-5015 layouts. Send us your part number and we will propose the matching configuration and samples for your mating test.
Part number, drawing, pin-out or a short description of your application.
Our engineers match the configuration and reply with a drawing and quotation.
Samples are built to order. The minimum order quantity is 10 pieces, and samples and production orders each take 4–8 weeks. Third-party testing to your specification is available on request.
You test the samples in your own equipment and approve them.
Production follows the approved sample configuration, with machining, molding, plating and assembly in our own Shenyang factory.
Send your part number, pin-out or drawing. Every inquiry is acknowledged by email within 1 business day, and an engineer follows up with a matched configuration, drawing or quotation.
