CDb Series High-Density Rectangular Connector
The CDb series is a high-density small rectangular connector using twisted-wire elastic pins (“twist pins”) for maximum contact density. Seven contact layouts are available — 13, 19, 31, 33, 52, 79 and 100 — and the 13-contact version carries two additional high-power contacts rated 30 A. Except for the CDb-33 plastic-shell version, all variants use metal shells that are interchangeable with J18 series housings. Crimp, solder and right-angle PCB terminations are offered with matching locking kits and mounting brackets.
