Dual Axis PowerProbe (DAPP Series)
High performance magnetically-coupled devices designed for sample transfer with outer shaft linear motion and independent rotary motion of inner shaft. Ideal for systems where a secondary motion is required to actuate an end-effector mechanism. Range includes end-effectors to transfer industrystandard flag and puck sample holders.
- Independent linear & rotary motion
- Unrivalled axial coupling strength
- 10x thrust and 4x torque compared to conventional devices
- Exceptional axial stiffness
- Zero backlash under low load
- Bakeable to 250°C without removing any components
The Dual Axis PowerProbe (DAPP) has two concentric output shafts providing independent axes of motion. The outer tubular shaft has linear only motion provided by the linear PowerProbe magnetic coupling. The inner shaft has independent rotary motion provided by the PowerProbe rotary magnetic coupling. The DAPP has a single driving thimble allowing simultaneous actuation of both the linear and rotary axes.
This PowerProbe variant is ideally suited to system designers who wish to employ a secondary motion to actuate an end-effector mechanism, such as a sample locking system, for example.
The Dual Axis PowerProbe benefits from our powerful magnetic coupling technology providing robust, reliable performance. Additionally, the internal linear guidance system, prevents rotation of the main shaft, thus removing the need for conventional external guide bars, providing an elegant and compact solution to sample transfer.
Two standard end-effectors are offered to grip and safely transfer industry-standard surface analysis flag and puck sample holders.
|Mounting flange||CF35 70mm (2.75") OD|
|Breakaway Torque||4 Nm (2.95 lbf ft)|
|Bakeout||250 °C without the removal of any components|
|Pressure Range||Atm to 5 x 10-11 mbar|
|Position Locking||Thumbscrew (manual only)|
|Break-away Linear Force||180 N (40.5 lbf) standard|
|Sample Weight/Load Capacity||Maximum recommended internal load carrying capacity will be a function of probe extension, but we recommend not to exceed a moment of 20 Nm (15 lbf ft). See Technical Data for deflection versus load graph.|
|Max Recommended Internally Applied Load When Vertically Installed||This is a function of the load acceleration. In a static case the load may approach the coupling break-away force, however, it would be wise to apply a sensible safety factor.|
