Overview
Landing gear bays subject wiring to repeated mechanical shock, hydraulic fluid exposure, and extreme temperature swings between ground and altitude, all while requiring precise sensor feedback for safe gear operation.

Design & Construction
Shock & Vibration-Rated Construction
Reinforced strain relief and vibration-rated clamping withstand the repeated mechanical shock of gear retraction and extension cycles, protecting sensor and actuator circuits over the airframe’s service life.
Hydraulic Fluid & Temperature-Resistant Sealing
Fluid-resistant overbraid and sealed circular connectors protect position sensor and actuator wiring from hydraulic fluid exposure and the wide temperature swings seen in wheel well environments.
Manufacturing Process
Built under AS9100D quality management with full first-article inspection and lot traceability, supporting landing gear OEMs and MRO providers on both new-build and retrofit programs.

Typical Applications
- Landing gear position sensor wiring
- Brake and anti-skid system cabling
- Actuator control and feedback harnesses
- Wheel well lighting and de-icing circuits
- Gear retraction/extension monitoring wiring
Common installations include Landing gear position sensor wiring, Brake and anti-skid system cabling, and Actuator control and feedback harnesses, where flight-critical reliability and stringent weight optimization are the primary design drivers. The same base design can also be adapted for Wheel well lighting and de-icing circuits and Gear retraction/extension monitoring wiring with minor changes to connector type or cable length.
