T-Series/Vacuum Compatible Devices

Vacuum Compatible Devices

Some Zaber products are available in vacuum compatible versions. Vacuum compatible devices (devices with the suffix “-V” in the part number) are identical to their non-vacuum compatible counterparts with the following exceptions:

Lubrication: All lubricated interfaces (motor bearings, leadscrews, leadnuts, etc) are cleaned and re-greased using a vacuum compatible lubricating gel (NyeClean 5077, vapor pressure ~5x10-9 Torr at 25°C). We make every effort to remove all trace of any original greases (some components arrive from our manufacturers pre-assembled, and pre-greased) but for best results we recommend degassing devices before use in the final application.

Power: No power connectors are provided on vacuum compatible devices. Instead, power must be supplied through the data cable lines. A special serial adapter with power input is provided.

Data cable extensions: Vacuum compatible devices use the same mini-din cable extensions as our standard devices; however, the cable jacket is stripped back to the connectors to expose the individual wires. The mini-din connectors are left attached to facilitate easy testing. In your final application you can cut the wires and splice them to a feed-through on your vacuum chamber. Communication lines can be wired back to the appropriate mini-din connector outside your vacuum chamber. Power lines can be wired to any appropriate power supply. See the table below for pinouts. If you have multiple units inside the same vacuum chamber you may connect them using the attached mini-din connectors, or for improved vacuum compatibility you may remove the connectors and permanently wire the units together.
