Features ––––––––––––––––––––––––
The connection shown in the figure is commonly called "daisy
chain connection"s or "through 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 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 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.
