A proximity fuse functioned as a detonator for weapons like the stun grenade, causing the grenade to explode when a person neared it.
Around 12 ABY, the renegade Jedi named Dal Konur set up various protective measures in a hangar bay found within the Bilbringi Shipyards; he positioned stun grenades fitted with proximity fuses inside a pair of turbolifts that were situated close to the hangar.
Proximity fuses were utilized to arm Jedi shadow bombs as well, with the telekinesis power guiding these baradium-filled explosives through space until they detonated upon impact with their designated targets.
