Tilt Facility (LSMT) Linear Shift Mechanism Series
Smooth kinematic linear motion along the port axis (Z) with the additional facility to tilt the travelling flange so it serves as an integrated port aligner. This makes the LSMT ideal for applications where precise alignment with a fixed point is essential.
Features
- +/-2° tilt for final alignment
- Smooth kinematic motion
- Reliable, rigid construction
- Manual, pneumatic and motorised actuation options
- Demountable bellows assembly
- Up to 150mm stroke
- Adjustment via 4 threaded support shafts
- Bakeable to 250°C
The LSMT is based on the standard LSM series with the additional facility to tilt the moving flange by +/-2° for final alignment, acting as an integrated port aligner. Typically used on beamlines to align diagnositcs or for ion/sputter source alignment. Adjustment is actuated via four threaded support shafts. All flanges in the series are supplied with tapped bolt holes on the base flange as standard.

Actuation Options
The series can be actuated with a manual handwheel, pneumatic cylinder, DC motor or stepper motor.
 Manual |
 Pneumatic |
 Motor |
| Code | Actuation Method | Description |
| H | Manual | A manual handwheel provides the most basic method of actuation. |
| P | Pneumatic | Pneumatic actuators provide a simple solution to automated operation. |
| PS | Pneumatic | Pneumatic actuator with reed switches. |
Motorization
| Code | Actuation Method | Description |
| SD | DC Motorized | A 24V DC motor provides the motion and is mounted to the side of the LSM. |
| SS | Stepper Motor Driven | A stepper motor provides the motion and is mounted to the side of the LSM. |
| UP | Wiring Upgrade | When purchasing A LSM for use with one of our controllers, an additional wiring upgrade is available. The upgrade includes a bakeable socket connector, mounted to the frame, to which the limit switches are pre-wired. In the case of stepper motor driven products, an extra home switch is also provided. The motor lead terminates with a connector for plug & play connection to the controller. |
Position Readout/Feedback Options
| Code | Item | Description |
| ES | Engraved Shaft | Linear Shift Mechanisms can be fitted with a scale with 1mm increments for visual positioning. |
| DLA | Digital Linear Scale | Digital scale displays are fitted to Linear Shift Mechanisms via a kinematic mount ensuring precise and repeatable location, which is critical for accurate repositioning after bakeout. The scale features large, easy to read characters that can be switched between metric and imperial units. The readout has a resolution of 10 microns (0.01mm). Users can set the ‘Origin’ at any position of its travel, from which it will provide a plus/minus scale in the units selected. The ‘Origin’ is retained in its memory until re-set by the user, even when switched off. A second temporary ‘Zero’ facility is offered to enable one-off measurements to take place, which resets to the ‘Origin’ setting when turned off. |
| UP | Wiring Upgrade | Wiring upgrade with switches for connectivity to controller options. |
