CD Card Edge Sockets

CD452A Solder and Vertical Card Edge Sockets
CD448 Black and Blue Card Edge Sockets

Description

Card edge socket selection

CD452A and CD448 have flanged card edge socket bodies with two opposing contact rows. Choose the longitudinal contact pitch and termination style together; the two models have different contact counts and mounting dimensions.

CD452A outline and terminals

The drawing identifies count-dependent longitudinal dimensions A–F but does not provide their numeric table. Use the corresponding count-specific outline when establishing overall length or mounting-hole spacing. The illustrated mounting holes are Ø3.5mm.
