Micro-USB interconnects

18 August 2010 Interconnection

A new series of Micro-USB plugs and sockets with up to 4,8 Gbps data transfer speeds is now available from Keystone Electronics. These sockets boast reduced PCB footprints and support USB On-the Go (OTG) technology for mobile device connectivity without a host computer. Designed for extended durability, the new USB 2.0 and USB 3.0 products can withstand greater than 10 000 mating cycles. A unique socket lead-in design enables blind-mating with the plug. Plugs and sockets are manufactured with gold plated contacts for reliability and low contact resistance.

Part number 940TR is a surface mountable Micro-USB 2.0 Type B socket available on tape and reel to simplify pick and place installation. Insulating material is UL94V-0 rated. Part number 955 is a through-hole mountable Micro-USB 3.0 Type B socket that delivers data transfer speeds to 4,8 Gbps.

Keystone’s Type B Micro-USB plug kits – part numbers 941 for USB 2.0 applications and 957 for USB 3.0 applications – are well suited for creating custom cable assemblies. The kits are supplied with an unassembled metal housing with strain relief. All USB 3.0 sockets are backward compatible with USB 2.0 plugs.
