Custom XT30 & XT30(2+2) harnesses

XT30 harnesses, built to your exact length.

Choose XT30 for power only, or XT30(2+2) for power plus two signal wires (CAN) in one plug. Then pick the length, wire gauge, how each end exits, and the wire colors. We solder, crimp, test, and ship it. From $20.09.

Built like the harnesses in our own robots

Bokchoy is the harness shop behind the Almond Axol dual-arm robot. Every order is built to the same drawing standard and parts as our production cables.

Connectors

XT30: the standard 2-pin power plug. XT30(2+2): 2 power + 2 signal pins, mates with the XT30(2+2) male headers on Damiao, MyActuator and similar actuators. Female plugs, gold-plated contacts.

Power wires

Red or black, 14, 16 or 18 AWG UL3135 silicone, 0.08 mm tinned strands. Soldered to the power pins, each joint sealed in 2:1 heat shrink.

Signal wires (XT30(2+2) only)

Green or yellow, 24 AWG UL3135 silicone (40/0.08 mm), crimped into the connector's signal sockets. Twisted at a ~12 mm lay by default.

Terminations

Each end independently straight or right angle. Right-angle ends bend 90° at the solder joint; on XT30(2+2) the power wires go toward or away from the signal pins.

Tolerance

±5 mm under 100 mm, ±15 mm up to 600 mm, ±20 mm to 1200 mm, ±25 mm beyond. Length is the wire only, measured from the back of one plug to the back of the other.

Testing

Every harness is 100% continuity and short tested (≤ 3 Ω, insulation ≥ 10 MΩ) before it ships.

Assembled in the USA

Every Bokchoy harness is cut, soldered, crimped, and 100% tested by hand in the United States, to the same drawing standard as the cables inside the Almond Axol robot.

Questions

XT30 or XT30(2+2)?+

XT30 is the common 2-pin power plug for batteries, ESCs and power boards. XT30(2+2) carries power plus two signal wires (usually CAN) in one plug: it's what Damiao, MyActuator and similar CAN actuators use, and what we build for the Almond Axol arm. Match whatever male connector you're plugging into.

Which gauge should I pick?+

Use 14 AWG for long runs or motors that pull more than ~20 A continuous, 16 AWG for most robot joints, and 18 AWG where flexibility and bend radius matter most. The XT30 contacts are rated 30 A.

Which way does a right-angle end bend?+

On an XT30(2+2), the power pins sit in a row with the signal pins at one end. 'Toward signal' bends the power wires 90° toward the signal-pin end of the plug; 'away from signal' bends them toward the opposite end. The preview draws every plug with its signal pins on top, so toward-signal wires go up and away-from-signal wires go down. The plain XT30 has no signal pins, so it has a single right-angle option.

How long does it take, and where do you ship?+

Lead time is 1 week: every order is built, tested, and shipped within 5 business days. Then pick US Ground (2–5 days), Two-Day, or Next Day at checkout; shipping is priced by your order's weight. We ship within the US only for now.

Can I get something not listed here?+

Yes. Pigtails, ring terminals, branches, other connectors: download your spec and email it to us, and we'll quote it.
