5.1.1.1 Pogo Pins
The Rosenberger pog o pins have been qu alified by Cinterion for ap plications with a 3mm
board-to-board connector stacking height. To ensure a reliable connection the module should
therefore be fixed at an equidistance of 3mm from the external application’s PCB. For details
on board-to-board connectors and stacking heights see Section 6.3. For ordering information
on the pogo pins see Section 8.1.
Figure 6 and Table 11 show the dimensions of the Pogo pins as well as some basic character-
istics. For further details and a test report please contact Rosenberger.
