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.
