Product Facts
■ Connector for signal circuits
with one row of contacts on
2.5 mm centerline
■ Wire-to-board and wire-to-
wire connectors, consisting
of plug and cap housings for
wire termination and PC
board-mount post headers
■ Mounted to plug and cap
housings for wire
application, double lock
plate provides for positive
loading of contacts in the
housing. It also helps
contacts mate completely
■ Double lock plate is
contained within the plug
and cap housing completely,
which provides neat overall
appearance
■ Accepts 26-20 AWG wire
(e.g. UL 1007, 1061, 1571,
etc.) with insulation
diameters of up to 1.8 mm
■ PC board-mount post header
is available in two styles:
standard profile and high
profile
■ High-profile post header has
locking feature at location
fit to resin coating, which is
applied onto the board for
waterproof protection as in
home appliances. It does not
hamper mating and locking
of post header with plug
housing
■ Locking structure is inner-
lock type and has a clean
surface
■ Solder tail section of post
header is provided with kinks
to retain the header firmly on
PC board during soldering
■ Radial tape-mounted version
of post header is also
available that is applicable
to radial mounting machines
■ Recognized under the
Component Program
of Underwriters Laboratories
Inc., File No. E28476
■ Certified by Canadian
Standards Association,
File No. LR7189
■ VDE Approved, File No.

2.5 mm Signal Double Lock
Connectors (2.5 SDL) are
2.5 mm centerline, com-
pact, one-row connectors
for signal circuits.
With contacts on 2.5 mm
centerline, both wire-to-wire
and wire-to-board connec-
tors are available.
The connectors consist of
plug and cap housings for
wire termination, double
lock plates for plug and cap
housings, crimp snap-in
contacts, and a PC board-
mount post header. A dou-
ble lock plate is available
for both plug and wire-to-
wire cap housing to provide
for positive loading. It helps
prevent contacts from com-
ing off or mating halfway.
The plate is contained within
the plug and cap housing
completely. The plug and
cap housing can be used
without a double lock plate.
The connector accepts 26-
20 AWG wire (e.g. UL 1007,
1061, 1571, etc.) with insu-
lation diameters of up to
1.8 mm.
The PC board-mount post
header is available in two
styles: standard profile and
high profile.
The high-profile type con-
nectors can be used for
home appliances, which
require waterproof protec-
tion. It does not hamper
mating and locking of the
post header with the plug
housing, even if the board
has resin coating on it.
The locking structure is
inner-lock type and has a
clean surface.
The solder tail of the loose-
piece post header has kinks
to secure the connector
on the PC board until it is
soldered.
Radial tape-mounted ver-
sion of post header is also
available and this is appli-
cable to radial mounting
machines.
