JOHNEX INSTANTANEOUS ELECTRIC DETONATORS contain a priming composition of RDX base charge inside a cylindrical aluminium alloy shell, with red and grey lead wires and have been designed for use in the mining industry.
INTERDET® (inter-hole/inter-row) detonators consist of a single low strength, aluminium delay detonator, attached to a length of hollow plastic shock tube. The detonator is housed within a colour coded plastic connector block.
MEGADET® detonators are a series of high strength non-electric detonators with millisecond delay intervals ranging from 0 ms (instantaneous) to 1000 ms.
