Press Release Summary:
Radial Telescopic Transfer Arm (RTTA) provides sample reach of 760 mm beyond chamber connection flange. When fully retracted, arm will fit in chamber with ID of 630 mm and can hold up to 138 mm dia samples. Rotary feedthrough MagiDrives are used to achieve necessary actuation. While MD64LB has break-away torque of ~40 nm and provides stiff coupling, MD35 actuates mechanisms to drive arm in and out. True UHV rotation allows reproducibility of ≤0.5 mm fully extended to end stop.
Original Press Release:
New Radial Transfer Arm for Vacuum Applications
Detail: Jefferson Hills, PA.  The Kurt J. Lesker Company® is the exclusive North American Distributor for the brand new Radial Telescopic Transfer Arm (RTTA) from UHV Design. Designed for space efficiency, the RTTA provides a sample reach of 760mm beyond the chamber connection flange. When the arm is fully retracted it will fit in a chamber with an internal diameter of 630mm and can hold samples up to 138mm in diameter. The RTTA uses UHV Design’s rotary feedthrough MagiDrives to achieve the necessary actuation. The MD64LB has a break-away torque of ~40Nm, providing an extremely stiff coupling, ideal for rotating the "Arm" assembly. The MD35 actuates the mechanisms to drive the "Arm" in and out. The RTTA provides true UHV rotation with no oil, slip rings, bellows, or differential pumping, allowing a reproducibility of <=0.5mm fully extended to end stop. The benefit of this innovative design is that the RTTA chamber can be much smaller than those required for other transfer arms. This provides cost savings on the chamber itself, the vacuum pumps, and the frame while considerably reducing the overall footprint of the system.
