This 2.0 mm pitch insulation displacement
connector is another version of the NRD
connector for printed circuit boards.
The KRD connector allows daisy chaining
and is very useful in simplifying connection
systems in electronic equipment.
• Daisy chain connection
• Twin slot insulation displacement section
• Distortion resistant construction
• Interchangeability
• Low profile design - a mere 9.0 mm high from
the PC board surface

3. Hole dimensions differ according to the type of PC boards 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.
