Coming Soon: The T20 Stepper Track Actuator
We’re excited to introduce a major addition to the Actuonix lineup — the T20 linear track actuator. Designed as a hybrid of our T16 and S20 product families, the T20 combines the high-precision control of a stepper actuator with the space-saving, load-supporting benefits of a track-style design. It’s a versatile, compact solution for engineers and designers who demand accuracy, repeatability, and durability.
The T20 is built for applications where precise positioning is critical, and where the actuator must also support the load directly — without the need for additional external support mechanisms. Whether you're working on a prototype or developing for production, the T20 delivers the performance you need in a compact, reliable form factor.
What is the T20?
The T20 is a stepper-driven linear actuator featuring a moving carriage that rides on a slide rail, driven by an exposed lead screw. The actuator’s block is mounted directly to the rail and travels smoothly as the lead screw turns through it. This is a fundamentally different design from the T16, which uses an enclosed shaft and traveling block system. The T20’s layout provides improved side-load capability and consistent alignment — ideal for high-precision embedded motion.
Built around the same stepper motor platform as our S20 line, the T20 delivers accurate, repeatable motion with open-loop control. There’s no need for internal feedback systems — the stepper motor responds directly to command pulses, giving you simple, deterministic control over position.
Key Benefits of the T20
- Integrated Rail Support: The carriage rides on an internal slide rail, allowing it to guide and support the load through its travel.
- Stepper Motor Precision: Offers fine resolution and repeatable motion without feedback sensors.
- Compact and Efficient: Compared to rod-style actuators, track actuators like the T20 provide longer strokes without increasing overall actuator length.
- High Duty Cycle Capable: Built for long life and reliable performance in continuous-use applications.
- Controller Compatibility: Works seamlessly with the LAC Stepper Controller available on our website.
Why Track Actuators?
Compared to traditional rod-style actuators, track actuators like the T20 offer distinct mechanical advantages. The carriage travels along a fixed-length base, so the total length of the actuator doesn’t change as it moves — saving space and simplifying mechanical integration. The design also supports loads directly on the carriage, making it easier to implement linear motion in systems where side loading is expected.
The T20 provides an all-in-one solution for applications that require compactness, support for guided loads, and accurate control — without the complexity of adding external rails or guidance systems.
Ideal Applications
- Automation Equipment – Move tooling, sensors, or other components with high accuracy.
- Robotics and Mechatronics – Compact actuation for positioning or pick-and-place systems.
- Medical and Laboratory Devices – Ideal for enclosed systems where space and stability are both critical.
- Test Fixtures – Position probes, sensors, or mechanical components with consistent repeatability.
- OEM Embedded Systems – High-performance linear motion for production-level hardware.
The Future of Linear Motion
The T20 expands what’s possible in small-scale actuation. It brings together the strengths of two proven technologies — stepper precision and track-style load handling — in one compact, cost-effective package. As industries demand more from miniature motion systems, the T20 delivers the kind of integration-ready solution that designers have been asking for.
It’s a reliable, scalable option for modern automation challenges — and a sign of where micro motion technology is headed.
Frequently Asked Questions
Which actuator should I use for a drone payload release?
It depends on your payload size, release mechanism, and control system. For most small to mid-size UAVs, the L12-R or PQ12-R offers a great balance of size, weight, and performance. For heavier applications, consider the L16-R series.
Are Actuonix actuators compatible with common drone control systems?
Yes. Our RC-series actuators are compatible with most radio control systems and autopilot platforms like Pixhawk and ArduPilot. We also offer models that interface with Arduino and custom electronics.
Can I use Actuonix actuators outdoors or in harsh environments?
Yes, but we recommend taking precautions such as environmental sealing or using enclosures if exposure to dust, water, or chemicals is expected. Actuators can be integrated into ruggedized housings to improve field reliability.
