Magnetic Transporter

Magnetic Transporters for UHV are devices to introduce a sample into a vacuum chamber without breaking vacuum. Motion is achieved by use of magnets outside the vacuum to manipulate the mechanism inside the vacuum. The unique (patented) design of our heavy-duty transporters use a strong square hollow shaft instead of a round shaft providing very high performance. Traditional single shaft transporters are also available.

Product advantages:

• Higher rigidity
• Higher decoupling force
• Higher precision
• Longer extension without sagging
• Built-in 2nd operation for lift, etc

Models of magnetic transporters:

VFMS: Linear only; single shaft -- uses heavy duty square shaft.

VFMD: Linear + rotary; dual shaft -- a round shaft inside a heavy duty square shaft

VFML: Linear and/or Linear+rotary; single shaft -- uses single round shaft

VFMS and VFMD perform better than competition due to the use of heavy duty square shaft. Higher rigidity allows linear extension beyond 160" in verticle position and 60" in horizontal with little sagging. VFMD construction has a round shaft that rotates inside a square hollow shaft. Two shafts working independently allowing secondary operation such as clamping , lifting, rotation, lock and rotate stages which make them the best on the market. Conventional design uses a single round shaft for both axis. VFML is designed for light duty. It is based on conventional design (single round shaft) at a greater savings.

All magnetic transporters have the following common features

• Actuator Housing: Anodized Aluminum
• Magnets: NdFeB
• Vac. Range: 1x10-11 Torr
• Bake Temp: 250°C (carriage removed)

Numerous end-effectors are available for Magnetic Transporters. The independent motions of the VFMD-LR maniplators allow the rotation of the inner shaft to operate a cam for vertical lift, flex a gripper, open/close a pincher, rotate gear-box

Lite Duty, with round shaft Lite duty transporter, VFML

In addition to Square shaft, we also has the conventional round shaft design for the lite duty application at a cost saving.

Linear + Rotary

VFML‐LR

VFML-LR

Single round shaft magnetic manipulator is ideal for simple transfers requiring linear and/or rotary motion. It is less expensive than VFMD, and it offers superior linear force and torque to that of other conventional manipulators

Wobble stick, VFML-WS

Magnetically-Coupled Transfer Sticks are an economical way to perform simple linearangular motion within a vacuum system. They are robust and reliable reducing the risk of leaks by eliminating the use of edge welded bellows. Rare earth magnets "outside of vacuum" provide a strong magnetic coupling. With the external magnet carriage assembly removed, it is bakeable to 250°C. Standard TransferSticks are available with up to 12 inches of push-pull linear travel and an angular tilt of ± 11 degrees.
