TA-350 was the designation of a probe droid of the Sith Empire deployed to Belsavis during the Cold War. Stationed in The Tomb, he tasked an Imperial spacer to recover Rakata stasis technology from one of the vaults. When the spacer returned the samples to him, TA-350 uploaded them to Commander Calum on Proculus Station.

He was guarded during his deployment by battle droid KO-29.
