A:
There are 3 reasons
a. As far as market feedback is concerned, the transmitter (remote control) doesn’t need to require the IPX7 level, and the most common use scenario is to get caught in the rain, so rainproof is enough.
b. The remote control has several buttons, which would make the waterproof effect poor.
c. Due to the structure of the transmitter, the IPX7 will lead to an increase in the cost of funds.
Therefore, considering the actual use place, structural waterproof effect, and cost, the transmitter is selected as IPX5. Of course, if you have higher requirements for this, we can customize it.
