Header Connectors
Header connectors are often permanently mounted to
PC boards and mate with female socket connectors
having a .100 in. (2.54mm) x .100 in. (2.54mm) contact
spacing.
The headers have male pins on their mating side and
offer the designer a choice of either wire-wrap or solder
posts in various lengths on the opposing end.
With CW, the designer also can choose either straight
or right-angle contacts and allow sockets to mate
with headers at right angles or parallel to mating PC
board or wire-wrap plane. Optional ejection latches in
various sizes are available, to mate with strain relief or
non-strain relief sockets.
Polarization ribs are securely molded into place,
eliminating the need for gluing polarizing keys to the
header base. These ribs are easily removed for
applications requiring a non-polarized interconnection.
CW headers are Mil-DTL-83503/20, 21, 24 and 25
approved.
•Compatible with DESC-approved
polarization methods. Polarization
ribs are molded in place, eliminating
need for gluing. •Patented polarization ribs are
readily removable for use with
non-polarized sockets.
•Long or short latches
available for strain relief or
non-strain relief sockets.
•Designed for lower
locking force than
unlocking. Withstands
severe jarring and
vibration, yet permits
easy ejection of socket
when desired.
•Mateable with all
standard sockets,
having .100 in. x .100 in.
contact spacing, with or
without strain relief cover.
•Contacts are firmly seated in
the insulator to withstand
forces encountered in wire
wrapping process.
•Standoff pads between
connector and PC board
surface allow cleaning liquids to
run off, and air to circulate under
the header.
•Fully-shrouded design prevents
misalignment of connectors even
in blind applications. Traditional
design also available.

Ejection Latches
Ejection latches are available for all CW Header connectors. These latches
assure secure locking of the Socket to the Header, as well as simple,
trouble-free detachment of the mated Socket from the Header. An audible
click indicates that Header and Socket are fully mated. The latching surfaces
are consistent with DESC requirements for interchangeability.
Two latch sizes are featured—short for non-strain relief sockets and long
for strain relief sockets. For others, contact factory. Each latch is held
securely in place with a roll pin and can be removed at a work bench or
in the field.
Choose your polarization method from one of three options:
Method I: Grooves in sockets CWR-210 and 220 match up
with ribs on mating headers. (Mil-DTL-83503 approved
method.) For use with non-polarized sockets, the ribs may be
quickly, easily and cleanly removed with a simple tool in the
field, at a workbench or at the factory prior to shipment.
Method II: Plastic key inserted into socket contact prevents
mismating if corresponding header contact is removed.
Method III: In addition to mating socket grooves and headers
slots, central polarizing key on one socket side (CWR-217
and CWR-227) mates with matching central header slot.
