Amass SH3.5 Female Connector – SH3.5-F.G.B Original Drone Connectors

Product Description

The Amass SH3.5 Female Connector (SH3.5-F.G.B) is a high-quality 3.5mm high-current bullet connector designed for secure, efficient, and reliable power transmission in RC systems, drones, robotics, battery packs, Electronic Speed Controllers (ESCs), and various electronic applications. Manufactured by Amass, a globally trusted brand in connector technology, the SH3.5 series is widely used in compact power systems where stable current flow, low resistance, and strong mechanical connection are required.

The SH3.5-F.G.B Female Connector features a 3.5mm precision-machined brass contact with gold plating, ensuring excellent electrical conductivity and reduced contact resistance. The gold-plated surface helps prevent oxidation and corrosion, which improves long-term stability and ensures consistent performance even after repeated mating cycles. This makes it ideal for high-vibration environments such as drones and RC vehicles.

Designed for medium-current DC applications, the SH3.5 female connector provides a secure friction-fit connection with compatible SH3.5 male bullet connectors. The tight fit ensures stable electrical contact, minimizing power loss and preventing accidental disconnection during operation. It is widely used in motor-to-ESC connections where reliability and compact size are important.

The connector housing is made from high-temperature thermoplastic material (PA/Nylon) with flame-retardant properties, offering excellent insulation, mechanical strength, and heat resistance. Its compact cylindrical design allows easy installation in tight spaces while maintaining strong structural durability.

The SH3.5 connector is designed for solder-type wire termination, making it suitable for 14–16 AWG wires depending on application requirements. This allows users to create strong, low-resistance joints for efficient power transfer in demanding electronic systems.

Whether you're building a drone, assembling an RC aircraft, upgrading a robotic system, or working on a battery-powered project, the Amass SH3.5 Female Connector delivers dependable performance, compact design, and long-lasting electrical reliability.
