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.
