INSPIRE ROBOTS LA10-021D — 10 mm Stroke
The LA10-021D micro linear actuator integrates a compact 8V core-less brushed motor, precision planetary reducer, position sensor, screw mechanism, and closed-loop drive within a single unit. A built-in absolute position sensor retains location data even after power loss, eliminating the need to re-reference. It supports D-LVTTL communication for streamlined control, delivering up to 70 N of force with a 10 mm travel. The actuator measures 62.5 mm by 13.2 mm and weighs 23 g, making it suitable for space-limited systems. It features a self-locking function after power failure for safety and prevents unintended retraction with a max self-locking force of 100 N.
Precision and speed are balanced for small hardware projects: up to 0.02 mm positional accuracy, 8 mm/s full-load speed, and 18 mm/s no-load speed. Quick installation is facilitated by an M3 threaded interface and a complete debugging kit that includes a USB connection cable, a communication module, and a power supply unit. This makes the LA10-021D well-suited for robotics, education, and biomedical instruments where accurate, repeatable motion is critical in tight spaces.
INSPIRE ROBOTS LAS10-021D — 10 to 16 mm Stroke Options
The LAS10-021D family expands precision with a 16 mm stroke option and robust performance. It combines an 8V core-less motor, planetary reducer, absolute position sensor, and integrated force sensing for real-time feedback. With 0.03 mm repeatability, it maintains precise control across the stroke. The device weighs 24 g and has compact dimensions (44.5 mm by 24.8 mm). The self-locking feature activates after a power fault, with a high maximum self-locking force (150 N). Real-time feedback and D-LVTTL compatibility enable dependable closed-loop control in compact automation tasks, medical devices, and education kits.
INSPIRE ROBOTS LAS16-021D — 16 mm Stroke, Force 105 N
This LAS16-021D model adds a 16 mm stroke with higher force and integrated force sensing for enhanced precision and control. It offers 0.03 mm repeatability, a 16 mm travel, and a maximum force of 105 N. The actuator remains compact at 44.5 mm by 24.8 mm and 24 g, supporting space-constrained applications. A self-locking function provides power-off safety, with a 150 N self-locking threshold. It features real-time position data via built-in sensors and D-LVTTL communication for seamless integration into robotic arms, automation fixtures, and healthcare equipment requiring precise linear motion.
JQDML 0.4″ Stroke Mini Actuator — 188 N
The JQDML micro actuator offers a 0.4″ stroke (10 mm) with a robust 188 N maximum load and 12 V DC operation. A high-quality aluminum body supports durability, and built-in limit switches provide precise end-of-travel control with automatic stopping at the top. It is IP54-rated for environmental resilience and maintains quiet operation at under 50 dB. The compact unit includes standard mounting compatibility and is suitable for robotics, home automation, and compact devices that demand reliable translation with compact form factors.
AWINLI Mini1.2″ Stroke — 30 mm, 40.5 N
The AWINLI Mini actuator features a 30 mm stroke in a compact 12 V design with IP54 protection. Its aluminum housing and end caps provide durable construction for indoor and outdoor use. A built-in limit switch ensures the actuator stops at any position with a self-locking function to prevent drift after power-down. The 40.5 N rated force suits small cabinet doors, automated windows, and hobby robotics. The included mounting hardware and modular design simplify integration into space-limited projects.
Buying Guide: Key Purchase Considerations
- Stroke length and force: Match the travel distance and load in your application. Micro actuators typically offer 8–16 mm strokes with forces from roughly 40 N to 188 N, depending on model.
- Integrated sensors and control: Actuators with built-in absolute position sensors and force sensing provide feedback for closed-loop control, improving repeatability and safety in automation tasks.
- Power and control interface: Check voltage requirements (e.g., 12V) and whether the device supports direct drive control (D-LVTTL or similar) for simpler integration with microcontrollers or PLCs.
- Self-locking and safety features: Power-off locking helps prevent unintended movement. Consider maximum self-locking force and the overall safety profile for your environment.
- Size and weight: Compact dimensions and light weight are crucial for space-constrained applications like drones, small medical devices, and educational kits.
- Durability and protection: IP ratings (such as IP54) indicate environmental resilience. Aluminum housings offer robust durability against wear and corrosion in varied conditions.
- Installation and accessories: Look for Actuation kits that include mounting brackets, cables, and debugging tools to speed up integration and testing.
- Cost vs. performance: Higher precision, integrated sensors, and force sensing provide tangible benefits but assess whether the performance justifies the investment for your project.
- Compatibility: Ensure your control system and firmware support the actuator’s communication interface and data formats for reliable operation.
- Future scalability: If you anticipate expanding to more complex automation, select actuators with easy upgrade paths and broad ecosystem support.
Overall, micro precision linear actuators with integrated drive and sensors deliver compact, reliable motion for robotics, automation, and biomedical applications. When selecting, prioritize stroke and force that align with your load profile, sensor feedback for stable control, and installation ease to minimize integration time and maximize performance in space-limited environments.
