RA8-P36・Datasheet
1. Features
- Supports standard PWM control signals and is widely compatible with microcontrollers, servo controllers, and robot development platforms
- Built-in high-precision potentiometer position feedback enables smooth and stable closed-loop angle control
- Available in multiple physical travel options such as 180° / 270°, making it easier to match different mechanism travel requirements
- Supports a wide 6.0 V ~ 8.4 V input range, suitable for 2S LiPo batteries and common regulated power architectures
- Uses the industry-standard 25T output spline, compatible with common servo horns, metal arms, and structural accessories
- Uses a reinforced all-metal gear train with strong wear resistance and impact resistance
- Uses an aluminum CNC center case for better heat dissipation under high load
