Disconnectable Insulation displacement connectors
Features ––––––––––––––––––––––––
• Folded beam double-leaf contact construction
The contact springs are folded to increase their effective
strength. This design provides a safety margin that allows the
contacts to endure the distortion of misinsertion without being
permanently distorted.
• Twin U-slot insulation displacement section
The insulation displacement section connected to the wire
consists of two tin-plated slots (twin U-slot) for superb
reliability.
• Strain relief
The strain relief feature prevents stress due to vibration,
impact or bending from effecting the insulation displacement
connection. This is accomplished by holding the outside of the
wire with the insulation gripping device on the housing. To
ensure circuit integrity against vibration and undue tension,
ample clearance is provided between the insulation
displacement connection and the strain relief.
• Compatible with the PH crimp style connector
The KR connector features a mounting
height as low as 6.9mm (.272") and a
thickness as thin as 4.8mm (.189") (for top
entry type). It is suitable for
interconnection of a wide range of
electronic equipment such as VCRs, video
cameras, car stereo systems and
communication equipment.
The same shrouded header can be used for either PH crimp
style connector or KR insulation displacement connector. This
allows both types of connector to be used interchangeably
without replacing the header.
• Surface mount model (SMT)
This connector is also available in a surface mount
configuration. Its housing is made of heat resistant resin so
that it is not adversely affected during reflow soldering.
Because of its tiny size and ability to be surface mounted, this
connector meets the demand for high-density mounting of
components inside electronic products.

Note: 1. Tolerancesare non-cumulative: ±0.05mm(±.002") for all centers.
2. Hole dimensions differ according to the kind of PC board and piercing method. If PC board are made of hard material such as FR-4 are used, the hole
dimensions should be larger. The hole dimensions above should serve as a guideline.
