The shell of automotive sensitive equipment needs to be sealed to prevent the ingress of harmful pollutants such as water and dust, and at the same time, it needs to be ventilated to eliminate the sealing failure of the shell caused by pressure fluctuations. Therefore, these equipment must have waterproof and breathable function.
Application Overview
A: Sensor
B: Lights
