An all-electronic device for the detection and processing of those environmental signatures associated with the launching of a munitions round. The non-mechanical device imposes stringent requirements that the environmental signatures must meet before the device will issue a command signal to arm the round. Two transducers are utilized to sense two distinct conditions that are peculiar to the round's launching. In a particular embodiment, the two transducers used are a piezoelectric crystal that senses acceleration setback and a magnet and coil arrangement that is triggered when the round leaves the gun barrel. Furthermore, the environmental signatures that are sensed must fall within certain voltage ranges and time intervals that have been preselected according to the particular weapon and round combination under consideration. When the various signals meet all requirements, the device will provide a useable signal for any subsequent delay and arming function of the round.
