The NR connector is our first insulation
displacement connector designed for
printed circuit boards and has a justified
reputation for reliability. The receptacle
accepts both discrete wires and ribbon
cables.
Features ––––––––––––––––––––––––
• Twin U-slot insulation displacement section
The insulation displacement section connected to each wire
consists of two tin-plated slots (twin U-slot), which ensures
reliable connection.
• Strain relief
The housing has a strain relief feature that supports and
protects the insulation displacement connection from vibration,
shock and bending.
• Interchangeability
The shrouded header is interchangeable with the XH
connectors (crimp style), the NRD connectors (IDC style), and
the JQ connectors (board-to-board style).
Specifications –––––––––––––––––––
• Current rating: 2A AC, DC (AWG #24)
• Voltage rating: 250V AC, DC
• Temperature range: -25˚C to +85˚C
(including temperature rise in applying

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.
