The Ware for November 2014 is a linear actuator for ulta-high vacuum environments, with a pass-through. You can actually download a spec for the ware at 真空機器・部品.com. Thanks again to dmo and QB for letting me snag a couple wares and use them for the competition.
Albert got the correct first guess about it being a linear actuator for UHV environments (but missed the pass-through part). I really like Arnuschky’s detailed explanation, and he also identified the pass-through feature, so I’ll declare him the winner. Congrats, thanks for playing!
