JeffTron Micro Active Brake II with Wiring

Micro Active Brake II by JeffTron

This is a compact MOSFET module designed for installation in electric airsoft guns regardless of gearbox type. It features active motor braking, which stops the piston in the starting position after each shot. This prevents partial spring tension and prolongs the lifespan of internal components and the spring itself. The unit also eliminates unwanted double shots in SEMI mode in high-rate-of-fire setups. Installing this module results in increased rate of fire and longer battery runtime, as the MOSFET reduces electrical losses compared to traditional wiring.

Key Features

• Active motor braking uses the motor's energy to stop it
• No trigger contact arcing, zero idle power draw
• Protects and prolongs life of internal gearbox parts
• More effective with motors using neodymium magnets
• Requires fully functioning cutoff lever and gearbox mechanisms

Technical Specifications

• Device dimensions: 27 × 10 × 7 mm
• Maximum current: 75 A during shot / 25 A continuous (30 s)
• Supported voltage: 8.4–17 V (NiMH, LiPo, LiFe)
• Wiring type: 6-wire (power + signal)
• Designed for: AEG gearboxes
• Braking: Active, using motor’s residual energy

Package Contents

• Micro Active Brake II (with wiring)
• Shrink tubing
• Printed installation manual

Warning

Installation requires an experienced technician familiar with soldering and disassembling AEGs. Never use a transformer soldering iron!
