# Twisted Servo Extension Cable 12" Female - Female **Type:** Product page · **SKU:** POLOLU-2166 · **Brand:** [Pololu](https://core-electronics.com.au/brands/pololu-australia) **Page:** https://core-electronics.com.au/twisted-servo-extension-cable-12-female-female.html ([markdown](https://core-electronics.com.au/twisted-servo-extension-cable-12-female-female.html.md)) This 12-inch (300-mm), twisted cable has 22-AWG wires and female “JR”-style connectors on both ends, the same kind of connector commonly found on RC hobby servos. It can be used to make connections between devices with 0.1" 3-pin male headers, such as between RC servo controllers or RC receivers and motor controllers with an RC interface. It can also be a convenient way to connect various 3-pin sensors to a robot controller. The cable’s conductors each consist of 60 strands, making it much more flexible than standard servo cables, and the wires are twisted to reduce electromagnetic interference (EMI). ## Pricing - **Price:** $8.90 (inc GST) — $8.09 AUD, exc GST - **Quantity discounts:** 10+ $7.76 (exc GST) · 25+ $7.53 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 20 and Aug 24. ## Description This servo extension cable has [female JR connectors](https://core-electronics.com.au/jr-connector-pack-female.html) on both ends, so it can be used to make connections between devices with 0.1" 3-pin male headers, such as between [RC servo controllers](https://core-electronics.com.au/breakout-boards-and-modules/motor-drivers-controllers/servo-controllers.html) or RC receivers and [motor controllers](https://core-electronics.com.au/components/motors/dc-motors.html) with an [RC interface](https://core-electronics.com.au/category/53/rc-interface). The cable’s connectors are commonly found on [RC servo](https://core-electronics.com.au/category/23/rc-servos) leads and work with both [male JR](https://core-electronics.com.au/jr-connector-pack-male.html) and [male Futaba J](https://core-electronics.com.au/futaba-j-connector-pack-male.html) connectors. They have gold-flashed contacts on a 0.1" spacing and are joined by 22-AWG, 60-strand wires that make this cable more flexible than standard servo cables. **Note:** The cable’s female connectors are the same as what is found on most generic servos and fits nicely with [0.1" male headers](https://core-electronics.com.au/0-100-2-54-mm-breakaway-male-header-1x40-pin-straight.html), but is often referred to as “male” in the RC hobby industry. The picture below shows the cable connectors labeled with Pololu's gender convention. | [![](https://core-electronics.com.au/attachments/localcontent/0J3404_186386d2bf7.jpg)](https://core-electronics.com.au/attachments/localcontent/0J3404_1442467d1f2.jpg) | |---| | Female “JR”-style connector commonly found on servo cables (often referred to as “male” in the RC hobby industry). | These female-to-female cables are available in two styles: **[flat](https://core-electronics.com.au/servo-extension-cable-12-female-female.html)**, with wires stuck together side by side, and **[twisted](https://core-electronics.com.au/twisted-servo-extension-cable-12-female-female.html)**, with wires twisted around each other to decrease electromagnetic interference (EMI). The twisted versions are especially soft and flexible. These cables are also available in three lengths: [6"](https://core-electronics.com.au/twisted-servo-extension-cable-6-female-female.html), [12"](https://core-electronics.com.au/twisted-servo-extension-cable-12-female-female.html), and [24"](https://core-electronics.com.au/twisted-servo-extension-cable-24-female-female.html). | \| [![](https://core-electronics.com.au/attachments/localcontent/0J3374_12136b45290.jpg)](https://core-electronics.com.au/attachments/localcontent/0J3374_10653b321cb.jpg) \| \|---\| \| 12" (300 mm) female-female RC servo extension cable. \| | \| [![](https://core-electronics.com.au/attachments/localcontent/0J3430_1882157aa44.jpg)](https://core-electronics.com.au/attachments/localcontent/0J3430_1946895cf3a.jpg) \| \|---\|---\| \| Twisted servo extension cable 12" female – female. \| | |---| Pololu also sell [flat](https://core-electronics.com.au/servo-extension-cable-12-male-female.html) and [twisted](https://core-electronics.com.au/twisted-servo-extension-cable-12-male-female.html) male-to-female servo extension cables. **Servo cable color convention** - brown or black = ground (GND, battery negative terminal) - red = servo power (Vservo, battery positive terminal) - orange, yellow, white, or blue = servo control signal line **Note:** Cable color may vary from what is shown in the product picture.
