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
