Abstract
In a preferred embodiment, a safe and arm device for spinning munitions that takes advantage of the conservation of momentum law to impart a differential angular velocity to a ball rotating in a race within the device. The rotating ball is used to established discrete time intervals that can be integrated with an electronic counter to determine a safe arm distance, which distance can be programmed to be well beyond the 400-800 caliber arming distance achievable with conventional arming devices.
