Note: 1. The two holes are necessary when installing a shielding cover.
2. Tolerances are non-cumulative:
±
0.05mm for all centers.
3. Hole dimensions differ depending on the kind of PC board and piercing method. The dimensions above should serve as a guideline.
For details, contact JST.
4. The layout drawing is viewed from the receptacle mounting side.
5. When using a receptacle with shielding cover or with flange shielding cover, the pattern should be designed to connect the shielding cover and the shielding
tube, if necessary. (No need for the front shielding cover.)
