M-235 High-Resolution Linear Actuator with DC Motor
Highly dynamic, high forces up to 120 N
- Travel ranges 20 and 50 mm
- Minimum incremental motion to 0.1 µm
- DC motor allows high velocities
- Push / pull force capacity up to 120 N
- MTBF >10,000 h
Reference-class linear drive
Combines high precision, high forces, and high dynamics.
High-quality components
Ball screw for high velocities and a high number of cycles. 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
- Highly dynamic, closed-loop DC motors reach high velocities
- Position-controlled DC motors with a gearhead and high-resolution rotary encoders allow for incremental motion of just 100 nm
Application fields
Precision adjustment. External drive element for guided systems.
