5656 Series

Floating: XY+/-1.0mm High heat resistance

Advancements in automotive infotainment and driver-assist technologies are creating new demand for electronic connectors that meet two key requirements. First, they must operate reliably amid high temperatures; and second, they must maintain stable contact position against vibration and shock. The 5656 series connectors are specifically designed for these requirements, with heat resistance up to +125°C and a proprietary floating mechanism that provides mating tolerance of ±1.0mm*1 at maximum (F/P*2=200%) in both the X and Y directions — 2.2 times larger than Kyocera’s conventional connector products. This enhanced mating tolerance ensures reliable connections by compensating for a greater degree of location mating error and mounting slippage during assembly, as well as vibration and shock in the operating environment.

  • Kyocera's proprietary floating structure ensures reliable connections in the mated state even amid movement of up to ±1.0mm*1 at maximum (F/P*2=200%) in both the X and Y directions.
  • The 5656 Series connectors are available in two configurations: a straight type that mounts perpendicular to the circuit board for vertical insertion, and a right-angle type that mounts parallel to the board for horizontal insertion.
  • Also available are two specialized types that meet with a wide range of requirements: the power terminals attached type accommodates high current such as power supply purpose. Combinations of signal and power pins are also available.
  • Packaged in tape and reel: 400 or 500 pieces/reel
