3-to-3 4-Pin Aviation Connector Cable | Coiled Camera Extension for Trucks & Buses

Product Overview

The 3-to-3 Aviation Spring Cable is a professional-grade coiled extension cable designed for vehicle camera systems, MDVRs, and mobile surveillance equipment.
Built with pure copper conductors, reinforced PVC spiral insulation, and aviation-grade 4-pin connectors, this cable ensures stable signal transmission, excellent anti-interference performance, and long-term durability in demanding vehicle environments.

Its spring-type coiled structure allows flexible extension up to 8 meters, making it ideal for trucks, buses, trailers, and other commercial vehicles where cable movement and vibration are common.
