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 industry-standard flag and puck sample holders.
Available in standard stroke lengths from 304mm to 1219mm with motorization options. The LPP is bakeable to 250°C without removing any components.
For demanding UHV applications, we recommend choosing the "XDAPP" option with rolling metal & ceramic bearings for smooth, low friction actuation, with minimal outgassing.
Features
- 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.
Standard End-effectors
Two standard end-effectors are offered to grip and safely transfer industry-standard surface analysis flag and puck sample holders.
Specifications Table
Model/Series | Dual Axis PowerProbe (DAPP40) |
Mounting Flange Size | DN40 (2.75" OD) CF Flange |
Break-away Linear Force | 140 N (31.5 lbs) |
Maximum Cantilevered Load | 20 Nm (177 in-lbs) |
Available Stroke Range | 304mm (12") to 1219mm (48") as 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 ft lb) |
Bakeout | 250°C (motor removed) |
Pressure Range | Atm to 5 x 10-11 mbar |
Position Locking | Thumbscrew (manual only) |
Retracted Switch Option | Manually actuated drives may be purchased with an added "retracted micro-switch" to digitally indicate when the unit is in the fully retracted position. When used in conjunction with a PLC or other type relay, this can aid in ensuring a gate valve is not accidentally closed when the probe is in the inserted position |
