Waterproof servo connection?
« on: July 22, 2017, 05:45:14 PM »

Hi,
I am building a Robbe U47 and would like to control the front planes using a waterproofed servo (underneath the conning tower probably). The servo will be in the flooded front section and will need to be connected to the receiver which is obviously in the wtc. Since the two parts of the boat separate I will need to be able to make and break the connection in the servo wire - (this connection will be in the flooded area) Does this connection need to be waterproofed or am I worrying about nothing?

Hi Keith,

In the absence of any other replies to this one. Some links here may give you some ideas:

(I still feel that putting servos outside a WTC is best avoided,)

You could try the automotive style connectors, They seem pretty well sealed and come in 3 pin varieties.

I don't think water conducts enough to upset a servo connection at only 5 volts or whatever it is but, corrosion of the pins could be the issue over time if you didn't use a waterproof connector.

Hi,
Thanks for the replies. Perhaps I should rely on the rear planes for control.
Thanks again for your interest.
