Genuine AMASS MR30 Female Connector with Protective Housing - 3-Pin High-Current Motor Plug
In the 2026 drone landscape, where pilots demand both performance and aesthetic precision, the MR30 has replaced traditional bullet connectors for mid-range power systems. By housing all three motor phase leads in a single keyed connector, AMASS has eliminated the risk of incorrect wiring while significantly reducing the time required for motor swaps.
Key Technical Advantages:
Anti-Reverse Polarization: The asymmetrical housing ensures that the motor can only be plugged in one way. No more double-checking phase wiring in the field; just plug and fly.
Integrated Solder Sheath: The grey snap-on housing protects solder joints from shorts and mechanical stress. It offers a clean look and a solid grip point for disconnecting wires without pulling on the cables themselves.
High-Purity Gold Plating: The 2-micron gold coating over brass contacts ensures minimal internal resistance, preventing heat buildup even during aggressive high-throttle maneuvers.
Vibration-Proof Friction Fit: Engineered to withstand the high-frequency resonances of 20,000+ KV micro motors, the MR30 maintains a secure connection that won't vibrate loose mid-flight.
Weight-to-Power Optimization: Weighing only ~1.2g, it handles the current of a 1404 or 1507 motor while being significantly lighter and more compact than three individual 3.5mm bullet connectors.
FAQ: Top 5 Questions on AMASS MR30 Female
Q1: Why use MR30 instead of standard bullet connectors?A: The MR30 is faster to plug/unplug, more compact, and prevents reverse-polarity errors. Most importantly, the integrated housing provides better strain relief for your wires than heat-shrink on individual bullets.
Q2: Is this for the motor side or the ESC side?A: The Female connector is traditionally used on the ESC side (the side providing power), while the Male connector goes on the motor leads. However, they can be used interchangeably depending on your specific harness design.
Q3: How do I install the protective housing?A: Slide the housing onto the three wires before soldering. Once the solder joints have cooled, slide the housing forward until it "clicks" into place on the back of the connector.
Q4: Can this handle a 5-inch freestyle drone's current?A: The MR30 is rated for 30A peak. While it can work on low-power 5-inch setups, it is ideally suited for 3-inch and 4-inch drones. For high-power 5-inch racing quads pulling 100A+, we recommend soldering directly or using 4.0mm bullets.
Q5: Is this compatible with other XT-series connectors?A: No. The MR30 is a 3-pin connector specifically for motor phases. It does not mate with XT30, XT60, or any 2-pin power plugs.
Expert Guide Question: Are you using this for a sub-250g cinewhoop or a high-torque robotics actuator? Depending on your peak amperage, I can help you confirm if your ESC's burst rating aligns with the MR30's thermal limits!
