INTRODUCTION:

Adam Tech HMCA Series Card Edge Connectors include Standard

and Express versions designed for PCB’s in Peripheral Component

Interconnect (PCI) applications. Each is manufactured in a four row,

high density package which is completely compatible to industry

standards and has specially engineered contacts which provide a

very short electrical path between boards. Adam Tech card edge

connectors are designed for high performance with solid board pegs

and precision located, selectively gold plated contacts which are

ideal in high speed, increased bandwidth applications
