BOARD/WIRE-TO-BOARD CONNECTORS SCA-2 CONNECTOR SYSTEM OVERVIEW The SCA-2 (Single Connect Attachment-2) connector system consists of headers and receptacles that enable the HDD (Hard Disk Drive) to backplane interface in enterprise storage systems. The header resides on the HDD while the receptacle is attached to the backplane. 40pos SCA-2 receptacles are designed to accept Fibre Channel drives, while 80pos receptacle accept SCSI drives. This interface is governed by Small Form Factor standard, SFF8451 and SFF8454. 12G SCA-2 receptacle connectors also conform to the requirement of SFF8680. The internal design enhancements and modified PCB terminations improve impedence, insertion loss and reduce crosstalk. The connectors operate at a higher bandwidth which supports 4G, 8G and 12G applications. The 12G SCA-2 receptacle offers footprint compatibility with 4G and 8G connectors, easing design migration. The SCA-2 connector interface utilizes high reliability, dual row, bladed-on-beam contacts spaced on 1.27mm pitch. The feature of first-mate/last break contacts provides sequential mating in accordance to SFF requirements. Robust alignment and polarization features in the drive interface allow blind mating. And, the dual ESD contacts provide paths for static discharge protection. Vertical backplane receptacles are available in 11.5mm and 17.5mm extended body height with options for through-hole solder, press-fit or surface mount board termination. SCA-2 headers designed for straddle mount board termination are also available.
