All ELCON drawer
connectors in this section
are RoHS compliant
Tyco Electronics offers a
wide selection of blind-
mateable “drawer” connec-
tors to suit modular
equipment designs. The
term “drawer connector”
was created to describe a
cabinet drawer where the
connector is installed at the
back of the drawer and is
mated by closing the
drawer. Since the “drawer”
is often times made with a
somewhat loose fit — to
enable easy opening and
closing, the drawer connec-
tor must provide sufficient
self-alignment and ideally a
floating connection to the
cabinet or drawer to keep
the connection from binding.
The power drawer connec-
tors in this catalog are
divided into two separate
categories: high power
drawers and low power
drawers. Specifically, the
product line names in these
two categories are:
High Power Drawer Connectors
■
ELCON Drawer Series
Connectors
Low Power Drawer Connectors
■
AMP Drawer Series
Connectors
■
Mini Power Drawer
■
Blind-mate Drawer
Connectors
■
Hybrid Mini Drawer
Connectors
Some of the benefits of the
power drawer connectors
from Tyco Electronics are
the robustness of the
housing designs and the
durability of the contacts.
High-end applications such
as networking switches and
servers want the lowest
possible voltage drop
across the connector.
For these applications the
high conductivity screw-
machined contacts with
either gold or silver plating
offer the best performance.
The contacts are the core
of the ELCON drawer
series connectors. For cost
sensitive applications the
different hybrid drawer
connectors offer a wide
variety of shapes and sizes
aimed at keeping cost mini-
mized and still providing a
reliable separable interface.
Regardless of the applica-
tion, Tyco Electronics offers
a wide variety of power &
signal blind-mateable
drawer connectors.

How to Tailor Your ELCON Drawer Connector
If you selected a standard drawer connector for your appli-
cation, before placing an order you need to specify your
application-specific requirements, such as housing type,
contact loading, and termination style. Layout forms for all
standard drawer connectors, such as the one shown below,
are available online at http://www.tycoelectronics.com or
can be obtained from Tyco Electronics customer service for
Pin Assembly
1. Choose one housing from the
Pin Housing Selection Menu
table. Place
an X in the appropriate guide pin circles, if guide pins are required.
2. Write the total quantity of each pin contact you require
for each pin
assembly
in the
Qty
column of the
Pin Contact Selection Menu
table.
3. Crimp contacts are shipped uninstalled. Threaded and PCB tail
contacts are installed by Tyco Electronics; enter the letter reference
of the desired contact in the appropriate contact positions on the
drawing: e.g., if you need a size #20 premate PCB tail standard con-
tact to be installed in contact position #10, write “Q” in circle #10.
4. Sign, date and send the completed form to your local Tyco Electronics
Sales Engineer.

ELCON Drawer Connector Mounting
All ELCON drawer series connectors can be fix-mounted or float-mounted using the designated shoulder screws to allow
improved gatherability for blind-mating of the connector. Panel cut out dimensions are shown on the customer drawing
specific to your ELCON drawer connector.
Panel Float Mounting
When float-mounting to a panel or chassis, use the stainless steel shoulder screws specified in the layout sheet or
customer drawing specific to your ELCON drawer connector. Shown in the sketch below is an example of how the
Top Drawer connector is float-mounted to a panel.

Panel Fix Mounting
As a rule of thumb, ELCON drawer connectors can be fix-mounted to a panel, in two ways: (1) by attaching a screw
through the top and bottom mounting flange of the housing; or (2) by attaching a screw into a threaded guide pin (for
those connectors that have one). An example of each case is shown in the sketches below.
Screw Through Mounting Flange of Housing
Fix to the panel by attaching a commercially available
screw and a washer through the top and bottom mounting
flange of the housing.
Screw Into Thread of Guide Pin (When Applicable)
You can optionally fix-mount housings that have a guide
pin by attaching a commercially available screw and
washer into the thread on the back of the guide pin, as
shown in the figures below.

ELCON Drawer Connector Mounting
(Continued)
Strain Relief and Wire Dress
If required, wires can be bundled together and supported
with cable ties. Wires must not be stretched or confined in
any way that would restrict the floating action of the con-
nectors. Therefore, the wires must remain perpendicular to
the connector and avoid an excessively sharp bend
radius. The minimum recommended distance for the cable
tie, and the minimum bend radius of a wire bundle are
shown in the figure to the right.
Cable Mounted Products
PCB Fix Mounting
When mounting to a PC board, the connector standoffs must be seated on the board. Hold-downs are recommended to
provide stability during the soldering procedure. PCB-mount hole patterns are shown on the customer drawing specific
to your ELCON drawer connector.

Connector Engagement
To provide for proper mating of the connector when the power supply unit is fully engaged into the system, the gap
between the pin and socket (shown as dimension “A” in the sketch below) must be within the limit specified in the
customer drawing for your ELCON drawer connector. Failure to meet this requirement may compromise contact wipe.
Refer to the customer drawing for details. ELCON drawer connectors are polarized and will only mate in the correct
orientation (see sketch below).
