X-Shift (LSMX) Linear Shift Mechanism Series
Linear motion along the port axis (Z) with the additional facility to adjust the travelling flange laterally (X axis) to facilitate alignment. The travelling flange angle remains constant throughout actuation.
Features
- +/-5 mm lateral (X) motion
- Smooth kinematic alignment
- Reliable, rigid construction
- Manual, pneumatic or motorized actuation
- Demountable bellows assembly
- True UHV performance
- Bakeable to 250°C
The LSMX is based on the standard LSM series. Where the LSMX version differs is that, in addition to the Z motion, the user has the option to adjust the X motion of the moving flange by up to +/-5mm via a manual thumb wheel.
This is useful if the user needs the flexibility to make lateral alignment adjustments to the linear shift without altering the travelling flange angle. A typical application would be the alignment of a sample holder with a sample transfer arm within the system.

Actuation Options
X-Shift Linear Shift Mechanisms can be actuated manually, pneumatically, or via a DC 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. No motor controller is provided. |
| SADC | DC Motorized | A 24V DC motor side-mounted with pre-wired switches and integrated "SADC" handheld controller. |
| SS | Stepper Motor Driven | A stepper motor provides the motion and is mounted to the side of the LSM, motor is provided with flying leads only (controller option provided separately upon request). |
| 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 direct plug & play connection to the MSMC 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. |
| EN | Linear Encoder | The linear encoder (EN) option is selected where position feedback of the Linear Shift Mechanism traveling flange is required for closed-loop control applications. The EN is a contactless high-speed linear magnetic encoder which features a compact sealed read head providing resolution of 10 microns. Designed for extreme environments, the EN can be interfaced to a number of analog devices such as a PLC or motor controller. The EN is attached to the LSM frame with a kinematic mount enabling it to be removed if bakeout is required. |
| UP | Wiring Upgrade | Wiring upgrade with switches for connectivity to controller options. |
