movement of daughter
board to accommodate
clamping of the heatsink
I Plated through-hole
mounting available
I Available with flying leads
I Extender card option
available
I Typical mating force for 304
contacts is 38 pounds
I Designed to withstand vapor
phase soldering
I Two rotatable (six position)
polarizing keys are provided
accommodating 36 possible
combinations
I Jackscrew hardware
available; consult
Tyco Electronics
I Different modular inserts

various configurations
The MICRODOT HDSM
connector is designed for
4 row .050 [1.27] pitch
density with a special low
force twist pin that meets
all requirements of MIL-
DTL-55302 and MIL-DTL-
83513. This high density
connector allows the use of
construction to double the
packaging density with
surface mount capability.
