Features ––––––––––––––––––––––––
The connection shown in the figure is commonly called "daisy
chain connection"s or "though connection"s. With these simple
connections, many signals can be bussed to many different
printed circuit boards. The NRD connector is constructed to
allow such daisy chain connections.
• Reliable insulation displacement construction
The contact is identical to that of the NR connector which has an
established reputation for superb reliability.
• Strain relief
Two strain relief sections are provided on the housing to
decouple vibration, bending forces and other external stresses
from the insulation displacement section.
• Interchangeability
This 2.5mm (.098") pitch insulation
displacement connector is another
version of the NR connector for printed
circuit boards. The NRD connector allows
daisy chaining and is very useful in
simplifying connection systems in
electronic equipment.
The shrouded header is interchangeable with the XH
connectors (crimp style), the NR connectors (IDC style), and the
JQ connectors (board-to-board style).

Note:
1. Tolerances are non-cumulative:
±
0.05mm (
±
.002" ) for all centers.
2. Hole dimensions differ according to the kind of PC board and piercing method. If PC boards made of hard material are used, the hole
dimensions should be larger. The dimensions above should serve as a guideline. Contact JST for details.
