About This Product

The SF20/HA combines a compact form factor with high-accuracy laser distance measurement. It can measure distances up to 100 metres and is designed to maintain sub-centimetre accuracy across its operating range under specified conditions. Its onboard servo driver also allows beam-steering applications when used with suitable mounting hardware, making it useful for advanced sensing and mapping setups.
