SD SERIES. STRAIGHT/METAL PCB D-SUB
The SD※B and SD※G Series D sub-straight dip soldering connectors are designed to be mounted vertically on
PCBs. Directly connected to the circuits on PCBs, they are suitable for saving labor in mounting. 9, 15, 25, 37,
and 50-contact models available.
(1) Compact and sturdy due to a metal shell.
(2) Saves gold by plating contacts with gold and
PCB-contacting parts with solder.
(3) Directly mountable vertically on PCBs in high de-
nsity and easily connectable to a cable plug.
(4) A wide variety of combinations available, such as
dip soldering (HD), crimping (CD), and ribbon IDC
termination (FD).
(5) Uses insulation made from highly heat-resistant
and chemical resistant glass-containing resin
(UL94V-0).
