Tamiya connector

A Tamiya connector is a type of DC power connector, commonly used on radio-controlled model vehicle battery packs, drones and chargers.[1] They are also commonly used on airsoft guns.[2]


The usual wiring has the positive (red) wire running to the terminal with a square profile, and the negative (black) wire running to the half-circle, half-square terminal. This is true for both genders of connector. The female sockets are in a male housing and the male pins are in a female housing. 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.

The picture above shows the plastic housing-based gender reference, which is against the convention and used by some hobbyists.

In some cases, Mini-Tamiya connectors are wired in reverse polarity. This is often the case with airsoft guns, where the square profile terminal is the negative terminal and the rounded terminal is the positive terminal.[3]


There is only one size of Tamiya connectors (The other larger one is a Kyosho Connector) The outside dimensions of the connector are:

  • 10mm x 6mm x 22mm (about 3/8" x 7/32" x 7/8")


Tamiya connectors are useful because the locking mechanism ensures they do not come undone easily.[citation needed]

The connector physically isolates the positive and negative wires so that the connectors remain safe to use in damp conditions. This makes them safe for use in relatively low-current applications (up to about 15 A) in dirty conditions (for example, model boats or RC cars used outdoors).
