Connectors are available in
both lever and bell crank
actuated styles and can be
provided as panel assem-
blies, separate housings
and contacts or as pre-
assembled with solder post
terminals.
Panel assemblies include a
housing with ACTION PIN
press-fit solderless contacts
mounted on an epoxy
board for rack application.
Separate housing assem-
blies and ACTION PIN con-
tacts allow customer
assembly. These can be
mounted as close as .625
[15.88]. More design lati-
tude for high density appli-
cation is provided by the
side entry lever-type con-
nector, permitting use of all
sides of the PC board for
edge-type I/O connections

required, Tyco Electronics
has a line of preassembled
connectors with tin-plated
solder terminals. All these
configurations are available
in a broad range of sizes.
With ZIF style connectors,
intermittencies can occur if
a contact comes to rest on
a piece of foreign matter
(dust and dirt particles)
found on PC boards. To
decrease the probability of
this happening, all connec-
tors have been designed to
include a wiping contact
which produces a wiping
action. This action, pro-
duced by the geometry and
bending movements of the
beam, pushes aside debris
and allows for good electri-
cal connection by cleaning
the actual point of contact.
In addition, all connectors
have removable wings
which make it possible to
repair or replace damaged
cam rails, handles, contacts
