While its muzzle energy is comparable to low end air rifles (around 10-20 joules or 7.5-
15 ft-lbs), it should be treated the same way as a firearm. All armatures fired from the EMG-02
have the capacity to penetrate 10% ballistics gel between 2-4" and could result in potentially
lethal injuries. Never point the device at anything you don't want to destroy. Treat it as loaded
at all times.
The device operates at medium voltage (60V), but carries extremely high amperage
(1600A+) during a shot, which is converted to high voltage (650V+) inside the drive coils. While
most of the components experiencing these transient high voltage spikes are protected from
the user, it is advised that you should never touch any internal components of the gun during a
shot, especially those near the barrel. 650V is more than enough to cause serious electrical
shock, personal injury or death.
It is important to never fire projectiles shorter than 0.75" in length or smaller than
0.25" in diameter. Doing so puts excessive stress on the power semiconductor switching
components due to a low inductance configuration of the drive coils. This increases flyback
voltage and switching current due to the lower reluctance of the smaller ferromagnetic mass.
To put it bluntly: IF YOU FIRE ROUNDS OUTSIDE OF THESE DESIGN PARAMETERS, THE POWER
SEMICONDUCTORS ABOVE THE BARREL WILL EXPLODE.
Above the barrel is the laser aperture, which is a 650nm <5mW laser pointer for indoor
aiming assistance (class IIIR). Do not look directly into the laser.
2.2 User-facing electronic components
- Take care to protect the exposed components (laser switch, charging cable, firing mode
switch and main switch) from excessive force. Never rest the gun in a position where
these components are stressed.
The EMG-02 has a few user-facing electronic components, around which the user should
exercise caution. These components are the laser switch, firing mode switch, main switch,
charging cable, and discharge resistor.
It is important to protect all user-facing components from water, dust and
contamination. It is due to the fragility of the components that this EMG-02 is still considered a
"Beta Test" version as some components are still vulnerable to damage if care is not taken to
protect them.
Projectiles are pushed out of the magazine by a pulsed solenoid, known as the injector.
On the EMG-02 the injector solenoid body is an internal component and not visible from the
exterior of the gun. The injector piston (the moving part of the injector) is visible from the front
view-port and rear view-port. In the rear view-port, the injector has a spring loaded mechanism
