Drones & unmanned systems

Harnesses specified around weight, space and vibration.

In a commercial or industrial unmanned system — aerial, ground or marine — the harness links the battery, motor controllers, sensors, cameras and radio modules inside a frame with little room and constant vibration. Wire gauge, routing, connector retention and any sealing are confirmed against your wiring diagram and requirements before anything is built.

Typical assemblies

What drone and unmanned-system builders need

01

Battery and power distribution leads

Battery-to-distribution-board leads with the high-current connectors you specify, sized to your continuous and peak current.

02

Motor and ESC harnesses

Three-phase motor leads and controller signal wiring, cut to arm length and protected where they pass through the frame.

03

Controller and sensor harnesses

GPS, IMU, rangefinder and telemetry leads on fine-pitch connectors, built to your pinout and labeled per port.

04

Camera and gimbal cabling

Thin, flexible power and signal leads for gimbals and payload cameras; shielding and flex needs confirmed against the payload.

05

Radio and antenna leads

Coax pigtails and module interconnects for control, video and telemetry links — connector, length and routing per your layout.

06

Payload and ground-equipment cables

Payload interface harnesses, charging leads and ground-station cables, overmolded or sealed where the requirement calls for it.

What matters here

What gets checked before the PO

Unmanned systems are short on weight and space, and everything on them vibrates. These details are confirmed before a harness is quoted.

Weight and spaceWire gauge, insulation and bundle size chosen against your weight budget and the routing space in the frame
CurrentContinuous and peak current per circuit, battery voltage and connector type — conductors sized to your figures and confirmed before quoting
VibrationStrain relief, tie-down points and service loops per your drawing; any vibration testing is agreed per project
Connector retentionLocking or latching connector series and any secondary retention — sourced as specified, never silently substituted
EnvironmentOperating temperature, moisture, dust and UV exposure. Sealing or an ingress rating is a requirement to confirm, not a default
Signal integrityShielding, and separation of power, video and RF runs, per your layout
Testing and recordsContinuity and pull-force per the agreed plan; workmanship class and records agreed in the quotation. No aerospace-specific certification is claimed
