Connector, MR30-F (female), Amass

The MR30 Female connector is a reliable three-pin connector designed for use in power systems for drones, RC models, electric motors, speed controllers (ESCs), and other electronic devices. Due to its compact size, high conductivity and heat-resistant housing, the MR30-F provides stable contact and protection against overheating even under prolonged loads.

This type of connector is often used in FPV drones and models where connection reliability and minimal current loss are important.
