BRAND SPECNA ARMS
The Specna Arms HAL ETU electronic control system is designed for airsoft replicas equipped with a V3 gearbox.
The system uses magnetic sensors with Hall-effect technology, providing extensive configuration options and precise trigger detection.
The technology provides high sensitivity even with light trigger pressure, increased resistance to wear and improved protection against external factors.
The system also features low- and high-voltage protection, as well as overload protection. If the system detects operation above 40 RPS, it automatically stops operation to protect the gearbox components.
Specna Arms HAL is also compatible with brushless (BLDC) motors, allowing the system to be used with high-performance electronic configurations.
