Tamiya connector

[2] The connector was designed by Japanese manufacturer Tamiya Corporation.

The male pins (female housing) connector is usually on the battery side.

In electrical and electronics engineering, the convention is that gender refers to the metal contact parts of a connector in order to avoid ambiguity.

A large number of hobbyist retailers selling these connectors refer to the gender of the plastic housing, which is against convention and can lead to errors.

This makes them safe for use in relatively low-current applications (up to about 15 A)[citation needed] in dirty conditions (for example, model boats or RC cars used outdoors).
