→ Memory Stick Socket Continued-Supply Guide

A Combo card connector (multi-card socket) reads several card types in one slot — SD, MMC, RS-MMC, MMCplus, MMCmobile, miniSD and MS — for card readers, printers, media players and general-purpose slots in industrial equipment. The KINGCONN Combo series has 8 models: 3 IN 1 (SD / MS / MMC), 4 IN 1, 5 IN 1, 6 IN 1 and Multi-Card sockets, plus SD+miniSD and an on-board 6-in-1 — each with a downloadable engineering drawing on its part page.

Selection FAQ

UL rating: 7 of the 8 part numbers in this series state this parameter on the drawing: UL94V-0 (7 part numbers)
How do I request a drawing or samples for Combo?
Email service@kingconn.com.tw with the part number. Clicking any part card on a product page also pre-fills the enquiry subject with that part number. Our sales team will reply with the drawing, samples and pricing.
Can Combo be customised?
Yes. The Taoyuan R&D team covers the full path from design and tooling to volume production, including medical-device ODM experience. Send us the application and the requirement, and sales and engineering will assess it together.
Can a combo card socket hold two cards at the same time?
No. A multi-card socket shares one slot and one contact set, so it reads a single card at a time; to read two cards simultaneously use two separate sockets, such as an SD socket plus a microSD socket. The part descriptions of the KINGCONN Combo series list the cards each socket supports.
How do I choose between 3-in-1, 4-in-1 and 6-in-1 sockets?
Choose the smallest set that covers the product’s cards: SD plus the MMC family (RS-MMC, MMCplus, MMCmobile) takes 4 IN 1 or 6 IN 1; adding MS takes 3 IN 1 (SD / MS / MMC); adding miniSD takes the SD+miniSD type. More card types means a larger socket; the supported cards are listed in each part description.
Is there a drawing for each Combo card connector?
Yes. Click any part card on this page to open the part page and download its engineering drawing (PDF); the dimensions, materials and plating in our spec tables are transcribed from those drawings.
