Amass Anti Spark AS150S Male Connector – AS150S-M.G.R Drone Connectors

Product Description

The Amass Anti Spark AS150S Male Connector (AS150S-M.G.R) is a premium high-current anti-spark DC power connector designed for safe and reliable power connection in agriculture drones, industrial UAVs, RC aircraft, electric vehicles, robotics, and high-capacity lithium battery systems. Manufactured by Amass, a globally recognized leader in connector technology, the AS150S series is engineered specifically to reduce dangerous electrical arcing during battery connection, improving both system safety and connector lifespan.

The AS150S-M.G.R Male Connector features a built-in anti-spark (pre-charge) resistor design, which controls inrush current when connecting high-voltage battery packs. This prevents the sudden electrical “pop” or spark that typically occurs in high-capacity lithium systems, especially in 12S–14S UAV and drone configurations. By gradually charging system capacitors, it protects sensitive components such as ESCs, BMS units, and power distribution boards from electrical stress.

The connector uses a 7mm gold-plated brass bullet contact, ensuring excellent conductivity, low resistance, and stable high-current performance. The gold plating helps resist oxidation and corrosion, allowing consistent performance over long-term use and repeated mating cycles. This makes it highly suitable for demanding outdoor applications such as agricultural spraying drones and industrial UAV systems.

Designed for high-power applications, the AS150S connector supports approximately 75A continuous current and up to 150A peak current (depending on wiring and cooling conditions), making it suitable for heavy-duty power systems. It is also rated for up to 500V DC systems, ensuring compatibility with modern high-voltage drone architectures.

The housing is made from high-temperature PA66 (Nylon) thermoplastic with UL94 flame-retardant properties, offering excellent insulation, mechanical strength, and thermal stability. Its rugged construction ensures resistance to vibration, shock, and harsh operating conditions commonly found in UAVs and mobile robotics.

The AS150S series is widely used because of its patented anti-spark design, which significantly improves safety during battery connection and reduces long-term wear on connector surfaces.

Whether you're building a professional drone system, designing a high-voltage battery pack, or working on industrial robotics, the Amass AS150S Male Connector provides a safer, more durable, and high-performance power connection solution.
