Sensor for ROS robots

The Yahboom Silan A3 lidar sensor delivers 360-degree scanning for robot navigation and mapping. It operates at a measurement frequency of 8000 to 32000 times per second with a scanning frequency of 10 to 20 Hz. The sensor suits developers building service robots or AGV systems.

Class 1 laser and brushless motor

A low-power infrared laser meets Class 1 safety standards for eye-safe operation. The self-designed brushless motor replaces the previous belt drive to reduce mechanical friction and noise. These features support reliable indoor or outdoor deployment.

Compact integration for autonomous platforms

The sensor provides contour mapping for obstacle avoidance and parking detection. Its rotation mechanism enables continuous environment scanning without bulky mounting requirements. Buyers needing longer range or higher resolution than 32000 measurements per second should consider other sensors.

Questions about this item

How often will the brushless motor need service or replacement?

The brushless motor removes the belt drive used in earlier designs, cutting mechanical friction so the motor runs smoothly with almost no noise and no scheduled replacement interval.

What limits continuous scanning — the 32000 measurements per second ceiling or the 20 Hz rotation cap?

The 20 Hz rotation cap is reached first; at that speed the sensor still delivers up to 32000 measurements per second, so scan rate is the binding limit.

How much heat and noise does the unit produce when it runs all day at 20 Hz?

The brushless motor runs very smoothly with almost no noise, and the Class 1 low-power infrared laser stays at eye-safe levels, so heat and acoustic output remain minimal during continuous operation.
