1. Plated through mounting holes for .062
″
[1.57] board thickness.
2. The connector should be fixed to the PCB by screws, tools or other
means during the soldering process. To prevent soldering defects, the
screws (M2.5) should not be tightened excessively.
3. The connector must be fixed to the PCB by board lock screws after
soldering. The connector should be fixed to the panel with panel mount
screws or jack sockets. See TS-0142 for mounting hardware.
