L-220 High-Resolution Linear Actuator
Suitable for High Cycle Numbers
- Forces to 125 N
- Travel ranges 13 to 77 mm (½" to 3")
- DC or stepper motor
- Vacuum-compatible variants available
Reference-class linear drive
Combines high precision, high forces, and high dynamics. Versions available for vacuum environments to 10-9 hPa.
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.
