Police and Security News reports that TASER has been developing a new launchable TASER ECD, the 40mm HEMI. “The letters stand for Human Electro-Muscular Incapacitation and 40mm means that it is compatible with existing 40mm low velocity weapons such as the M203, M320, M32, etc. TASER International is working with military customers to develop this capability. The 40mm HEMI will eventually be made available to law enforcement, too, but the current focus is on meeting military requirements . . .
The 40mm HEMI works much like TASER’s handheld ECDs (the venerable X26), but without the tethered wires required for the handheld ECDs. It is deployed as a projectile from a 40mm launcher and the front end’s nose with tiny metal barbs latch onto a person’s skin or clothing. These barbs double as the positive electrodes delivering the TASER effect. The back end section containing the negative electrodes separates on impact to create spread between the electrodes.
These two sections create a “circuit” for the series of electrical TASER pulses which incapacitate a human for a 30 second period of time. The 40mm HEMI round is capable of reaching a target up to 164 feet away . . .
In both the XREP and the 40mm HEMI, the battery supply is fully integrated into the projectile chassis. The XREP projectile produces a 20 second shock, while the 40mm HEMI is being designed to provide a longer duration because it has a greater range.”
