The TFA300 has an IP67 waterproof housing. It is recommended to directly expose the front window of the TFA300 to the air for use. Do not add an additional transparent housing to cover the window, as this may cause crosstalk due to multiple reflections and affect the distance measurement performance.

The TFA300 series utilizes a laser source with a central wavelength of 905 nm. It is recommended to use materials with a transmittance greater than 90% at 905 nm to minimize the impact of laser energy loss on ranging performance.
