T-Cube Laser Diode Driver
Appendix A Rear Panel Connector Pinout Details
A.1
Power Connector
Thorlabs recommends that the Laser Diode Driver T-Cube is operated with Thorlabs
power supply TPS002, as it was spe cifically designed for use with this p roduct.
However, to enable customers to use the cube in installations where a ±15V and 5V
power is already available, the laser diode driver cube can be operated with a different
external power supply, such as a bench or lab supply.
In this case ho wever, extreme care mu st 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 re sult 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 conn ected 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.
