CMD Series
4 Contact Row High Density
Signal Connectors
•
Offset-grid contact layout, four contact rows within
dielectric connector body, 1.905 mm center-to-center
contact spacing in each row and 1.905 row-to-row
spacing.
•
0.6 mm nominal pin DIA contact size; 42 to 316
contact positions; dip solder and SMT soldering
contact termination types.
•
High contact density, low connector weight, low
mating force. High shock and vibration proof (no
micro interruptions - test: 2ns).
•
Conforms to MIL-DTL-55302 general requirements,
and TPR 02013. CSD conforms to ESA specification.
•
For Civil, Military, Aerospace and Space applications.
