Electric actuator L-220 series

linearstepperball screw

Nonrotating tip: Avoidance of transfer of runout errors on contact point Highest precision: Minimal incremental steps of 100 nm, unidirectional repeatability ±0.25 µm Direction-sensing reference switch: Reduction of time required for referencing move, possibility of application-dependent referencing to avoid collisions Reference-class linear drive Combines high precision, high forces, and high dynamics. Models available for vacuum environments to 10-9 hPa. Travel ranges 13 mm to 77 mm (½" to 3"), forces to 125 N, DC or stepper motor High-quality components Ball screw for smooth feed. Nonrotating tip for uniform motion prevents wobble, torque, and wear at the point of contact. Incl. flat and spherical tip for decoupling forces. Noncontact limit switches protect the mechanics. A direction-sensing reference switch supports automation applications. Position-controlled variants with differential encoder driver in the connector for safe signal transfer over distances up to 10 m. Motor variants Position-controlled DC motors with a gearhead and high-resolution rotary encoders allow for incremental motion of just 100 nm High-performance and low-vibration 2-phase stepper motors with gear ratio allow precision positioning even without position control Application fields Research. Automation. Optical alignment.
