Product Description
Overview
The FEEtech STS5420M is a compact low-profile bus servo designed for robotics and precision motion control. It features a coreless motor, magnetic encoder, and 360° position control (0–4096), making it suitable for multi-turn and continuous rotation applications.
Key Features
- 25KG Stall Torque @ 7.4V – Suitable for medium-load robotic joints
- 360° Rotation (0–4096 Position Control)
- Magnetic Encoder Feedback – Stable and repeatable positioning
- Coreless Motor – Fast response and smooth operation
- Metal Gear Train – Improved durability
- TTL Bus Communication – Supports multi-servo control
- Low Profile Size (40.6×20×30mm) – Easy integration in compact designs
- Programmable Parameters – ID, speed, acceleration, position
