Connector Pinout Details

Power Connector
Thorlabs recommends that the position aligner cube is operated with Thorlabs power
supply TPS002, as it was specifically designed for use with this product. However, to
enable customers to use the cube in installations where a ±15V and 5V power is
already available, the piezo cube can be operated with a di fferent external power
supply, such as a bench or lab supply.
In this case h owever, extreme care must be taken to ensure that it meets the
specifications and is connected to the cube correctly. Out of tolerance supply voltages
or incorrect connection, applied even momentarily, can result in the sensitive
electronic components inside the cube getting damaged, invalidating warranty.
The cube uses a standard “mini-DIN” type of input connector, the corresponding plug
is available from most standard electronics suppliers.
Fig. A.1 shows the mini-DIN socket as viewed by looking at the rear panel of the cube.
The pin numbering follows the standard for mini-DIN connectors.

Warning
When wiring the mini-DIN plug, ensure that all the ground pins are used
and the shield is connected to common ground. This provides a level of
protection against overvoltages due to loss of ground. A “loss of ground”
condition can seriously damage the electronics inside the cube
