Servo connector

From RC Helicopter Wiki

Four types of servo connector are in common use:

• 

  

  Futaba J connector
  Futaba J

Futaba J connectors are three pin polarized connectors that have a polarizing tab on the signal wire, and chamfered corners on the underside (older Futaba J connectors may not have the chamfer).

• 

  

  JR connector
  JR, Hitec S and Airtronics Z

These servo connector is similar to the Futaba J, except that it does not have the polarizing tab, replyig on the chamfers for polarization. A Futaba J female connector can be plugged into a JR male connector if the polarizing tab is removed with a knife. All these connectors are physically and electrically compatiable.

• Micro JST

JST-ZH series connectors used by JR, Spektrum, and others when a smaller connector is needed.

• Futaba G (Futaba Micro)

Connector used on a small number of Futaba receivers (such as R616FFM) and servos (S3111M & S3114M), believed to be Molex Picoblade. Incompatiable with the normal Micro JST connector.

Hitec S connector

Airtronics Z (current) connector

Airtronics (old) connector
