Linear Actuator

Product catalog summary

Overview: The document details specifications and features of miniaturized AC Servo Linear Actuators, including models like MALS-D18, MAS-D16, and others. These actuators are designed for high accuracy positioning in various environments, including clean rooms.

Key Features:

Diameter: 16 to 28 mm.
Stroke lengths: 6 to 30 mm.
Rated thrust: 14.7 to 58.8 N.
Resolution: 0.24 to 0.625 μm.
Unidirectional repeat accuracy: 3 to 20 μm.
Bidirectional repeat accuracy: 5 to 25 μm.
Bidirectional positioning accuracy: 10 to 50 μm.

Specifications: Each series has specific models with varying specifications such as stroke, rated thrust, resolution, and accuracy metrics. For instance, the MALS-D18 series offers a stroke of 6/10/20 mm, rated thrust of 14.7 N, and resolution of 0.5 μm.

Design and Functionality: Actuators use a hollow structured AC servo motor and high-resolution optical rotary encoder. The direct design ensures precise positioning, with ball screws in MAB and MALB series for high speed and longevity.

Driver and Compatibility: The LAD-01 Series driver is recommended for smooth operation and zero vibration. Actuators are compatible with manual micrometer heads and adaptable for clean room environments.

Handling and Safety: Cautions include using the accompanying screw nut for fixing and not over-tightening the actuator housing. Safety mechanisms include end limit sensors for origin position detection.

Applications: Suitable for production, inspection, and experimental equipment in optical and semiconductor industries.

Procedures and Recommendations:

Mounting and Compatibility: Proper mounting using the screw nut is crucial.
Driver Usage: Use the LAD-01 Series driver.
Extension Cable: Use LAD-01D-012 line driver for extended transmission.
Limit Switch: Essential to prevent rod sticking.

Safety Mechanisms: Includes end limit sensor but lacks a brake mechanism, advising safety measures when not energized.

Notes and Cautions:

Avoid exceeding rated thrust to prevent damage.
Actuator cable is not resistant to bending stress.
Ensure torque does not exceed 1 Nm when attaching screws.

Technical Features: LAD-01 Series driver features a 3-phase sine wave PWM drive, microcontroller for control, and supports serial communication.

Additional Information: Definitions and explanations of terms like 'Origin Position' are in the glossary on page 15.

Specifications: DC 24V system with peak current of 10 A, position control with encoder resolution, and specific operating conditions.

Control and Display Functions: Supports various input signal configurations, alarm output reset, and origin position searching with LED indicators.

Cable and Connector Information: Details on cables and connectors, specifying lengths and types for different models and environments.

Accuracy Measurement: Follows JIS B-6201 standards, with formulas and diagrams for accuracy metrics.

Special Environment Models: Customization for low gas emissions environments, using fluorine grease and resin cables.

Handling and Safety Cautions: Emphasizes careful handling, proper wiring, and avoiding excessive stress.

Product Warranty: One-year warranty covering defects, with conditions for free repairs and customer responsibilities.

Specifications and Warnings: Cautions on screw length for fixing the driver and lifespan variations based on conditions.

General Information: Information subject to change without notice, with contact details for further inquiries.

Applications and Product Lineup:

Semiconductor Equipment: Includes lithography machines and wafer inspection systems.
Medical Equipment: Includes denture processing machines and ultrasonic diagnostic systems.
Beauty Equipment: Handpieces for nail art.
Measuring Equipment: Includes LiDAR and electron microscopes.
Factory Automation: Includes laser marking machines and motors for robots.
