The RC connector is a board-in type
insulation displacement connector for
1.27mm pitch ribbon cables. The number
of positions match the RA disconnectable
connector series so that they can be used
as a pair on opposite ends of a harness.
Features ––––––––––––––––––––––––
• Low profile with high-density mounting
The RC board-in connector has a low profile with a mounting
height of 6.8mm and a width of 6.54mm. It allows 2.54mm pitch
grid wiring for high density.
• Use with an RA connector
This connector and a RA disconnectable connector can be
used as a pair on opposite ends of a harness to reduce costs
and mounting space.
• Two kinds of plating
The contact comes in gold and tin-plated versions.
Specifications –––––––––––––––––––
• Current rating: 1.0A AC, DC
• Voltage rating: 300V AC, DC
• Temperature range: (including temperature rise in applying
electrical current)
-55˚C to +105˚C
• Insulation resistance: 5,000M Ωmin.
• Withstanding voltage: 500V AC/5 seconds
• Applicable wire: AWG #28
1.27mm pitch ribbon cable
• Applicable PC board thickness: 1.6mm
*Compliant with RoHS.
*Refer to "General Instruction and Notice when using
Terminals and Connectors" at the end of this catalog.
* Contact JST for details.
