APPLICATION NOTES
■ Stress limit to the connector: When connected, stress to
the connector should be limited as shown in Fig. 1.
■PCB mounting pattern dimensions: Dimensions shown
on page 323 “Recommended Mounting Dimensions”
should be used for PCB design.
■Disengagement and engagement:
Use tool P/N M19000. The connector to be disengaged
and engaged should be pulled out or insert to the vertical
direction using the tool. Do not try and pull out the cable
by hand or wire breakage may result.
■Cable and connector handling: Do not apply a twisting
torque to the cable and connector.
■REFLOW SOLDERING CONDITION: Reflow soldering
should be carried out according to condition shown
in Fig. 4.
1. Stress to the housing.
Stress A and B: 4.9N (0.5kgf) max.
2. Stress to the outer sleeve.
Stress C: 2.94N (0.3kgf) max.
Stress D: 1.96N (0.2kgf) max.
3. Stress to the cable.
Stress E: 4.9N (0.5kgf) max. for 81 cable
7.84N (0.8kgf) max. for 76 cable
