The MTA-50 IDC Connector
System is a wire-to-printed cir-
cuit board system with con-
tacts in a staggered, single
row on .050 [1.27] centerline.
The design features wire feed-
through capability for daisy-
chain applications. Insulation
displacement contacts are
used to terminate a wide
range of conductor sizes.
Ribbon cable can also be ter-
minated when the appropriate
receptacle assembly and
strain relief cover are used.
Header assemblies for board
mount applications include
right-angle (horizontal) and
vertical mount products.
These are available in
through-hole and surface
mount configurations.
Typical uses of the MTA-50
IDC connectors would be in
the Appliance, Commercial
and Home Equipment and
Security products industries.

Notes:
1. To determine connector overall
length (dim. A), multiply .050 x the
number of circuits and add .082.
Example: .050 x 10 circuits
equals 0.50 + .082 = .582 [14.78].
2. Strain relief covers shown on
page 6 are required and sold as
part of the Connector Kit.
3. Stranded UL Style 1061 or equiv-
alent wire is recommended.
4. Unless otherwise stated all toler-
ances (except plating) to be ±.005
[±0.13].
5. Consult Product Drawing for
RoHS Compliant information.
Note: Tin-plated connectors and
headers in even position sizes from
2–12 and 18 are stocked parts; all
other position sizes and products
with gold-plated contacts are
Make To Order.

Notes:
1. To determine connector overall
length (dim. A), multiply .050 x the
number of circuits and add .082.
Example: .050 x 10 circuits
equals 0.50 + .082 = .582 [14.78].
2. Strain relief covers shown on
page 8 are required and sold as
part of the Connector Kit.
3. Stranded UL Style 1061 or equiv-
alent wire is recommended.
4. Unless otherwise stated all toler-
ances (except plating) to be ±.005
[±0.13].
5. Consult Product Drawing for
RoHS Compliant information.
