Linear actuator MLA-CMA06
M-Thrust series precision actuators offer backlash-free motion of the shaft up to 25 mm travel range. Precision motion is accomplished by a miniature DC servo with rotary encoder or stepper motor providing 0.1 micron resolution. Precision fine pitch screw mechanism converts rotation of the motor shaft into linear travel while avoiding any backlash inside the system. This provides very responsive motion with exceptionally load capacity up to 70 N and low friction. M-Thrust actuators are offered in multiple travel ranges with limit switches at both ends of the travel.
- Stepper or DC motor driven
- Motorized screws design
- Small profile
- No backlash
- Built-in sensors
