The 2.5 mm signal double lock (2.5 SDL) connectors are compact, single row
connectors available in both wire-to-wire and wire-to-board configurations. The signal
double lock connector system consists of plug and cap housings for wire termination,
optional double lock plates, crimp contacts and PC board pin headers in both standard
and high profile versions. The signal double lock accepts 26-20 AWG wire with
insulation diameters up to 1.8 mm and is rated up to 3 Amps per line. Signal double
lock connectors are now available in material meeting the Glow Wire test according to
IEC 60335-1 5th Edition: Household and Similar Appliances — Safety (750°C, no flame)
and UL 94 V-0.

The signal double lock’s latch on the plug
housing and innerlocking cavity on the
cap housings helps prevent unintentional
disengagement and offers a snag-free
connection.
A double lock plate is available for both
plug and cap housings to ensure positive
loading and to help prevent contact
back-out.
Notes:
1. When ordering all housings and headers, use base part number and desired color code as the suffix. Housings meeting Glow Wire Test and V-0 are only available in Natural.
2. When ordering loose piece headers, use the prefix 2- to indicate the option of no polarization peg (boss).
3. When ordering radial tape-mounted headers, use the prefix 3- to indicate the option with a polarization leg (boss).
Example: 2-917785-2 is a 7 position, red loose piece header with no polarization peg (boss).
4. Available in a natural color only.

The solder tail of the loose-
piece pin header features
kinks to secure the connector
on the PC board until the
soldering process is complete.
The high profile type header
is designed specifically for
resin coated boards typically
used for waterproof protec-
tion in the manufacture of
home appliance PCBs. This
header is designed to mate
with the standard signal
double lock plug housings.
Signal double lock headers are available packaged on radial tape for use with radial mounting machines.

2.5 mm Signal Double Lock Connectors
Quick Reference Guide
Questions that will help you better select the product that you need:
What are the current and voltage requirements for your application?
The signal double lock connector system has a maximum current
rating of 3 Amps per line and is rated for 50 Volts AC/DC and
250 VAC.
What are the wire type and size requirements?
The signal double lock connector system is approved for use with
26-20 AWG wire with a wire insulation range between 0.93 mm
and 1.8 mm.
What are the number of positions and available space?
The signal double lock connector system is available in 2-13 position
wire-to-board and 2-10 position wire-to-wire configurations on a
2.5 mm pitch. The overall mated length of the free-hanging system
is 22.6 mm and the maximum height with the standard profile
header is 13.7 mm while the maximum height with the high-profile
header is 19.2 mm.
What are the flammability requirements for your application?
Signal double lock connectors are offered with various housings
rated UL 94 V-0, and meeting the Glow Wire Test according to IEC
60335-1 5th edition.
What are the operating temperature requirements?
The signal double lock connector system has a maximum operating
temperature of 105°C. For more information regarding operating
temperatures refer to Product Specification 108-5459.
Is contact back-out a concern? Do you need confirmation that the
contacts are seated?
The signal double lock connector system offers an optional double
lock plate. The purpose of the double lock plate is to allow the
contacts to be fully seated in the housing.
Do you need to differentiate this connector from other connectors
in the application?
The signal double lock connector system offers multiple options
of colored housings for ease of connector identification during
manufacturing and assembly.
What is the benefit of choosing high-profile over standard-profile
headers?
The signal double lock connector system offers high profile headers
for applications where there will be additional processing or resin
coating of the PCB’s during the manufacturing process.
What is the benefit of choosing headers with a polarization
peg (boss)?
The signal double lock connector system offers headers with or
without polarization pegs. The purpose of this feature is to polarize
the headers to the PCB so the header can not be placed on the PCB
in the wrong orientation. For more information regarding PCB layout
please refer to the header product drawing.
