Technical FAQ
Travel range: 50 mm · Sensor resolution: ~150 nm. Separate travel from resolution and both from repeatability. Repeatability is what an automated sequence actually depends on, and it is the figure most often absent from a headline specification.
Sencoder: Resistive Sensor · Sencoder range: 50 mm. Pair open-loop mechanics with the specified high-voltage or inertial driver, and closed-loop variants with the controller their capacitive, strain-gauge or encoder feedback requires. Matching connectors do not guarantee electrical compatibility.
Max. Load: 1.5 kg. Check the load rating in the orientation you will use it — a vertical or cantilevered load is a moment, not a mass — and match the base to an M6 pattern on a 25 mm grid or a 1/4"-20 pattern on a 1 inch grid.
Specifying this part
The LS series covers 30 to 200 mm of closed-loop travel with roughly 150 nm sensor resolution and 1–2 µm repeatability. It is the right choice for sample load-locks, filter exchangers and long-stroke scanner positioning, not for fine tracking.
Stick-slip inertial drives dissipate energy per step and draw no holding current once stopped, so the steady-state load on the mixing chamber is the wiring loom rather than the motor. Anchor the loom at each temperature stage and thermalise the moving body with an FTC copper braid.
Titanium bodies (BeCu on the .ULT variants) and BeCu fasteners throughout, rated for operation to 35 T and down to 30 mK with the .ULT option, at 2 × 10⁻¹¹ mbar with .UHV. A single steel screw substituted at installation is enough to compromise a high-field assembly.
