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.
Each connector block allows up to eight outgoing shock tubes to be initiated. The free end of the shock tube is closed with a waterproof seal and fitted with a plastic J clip for use with detonating cord.
INTERDET® detonators are designed to be used in conjunction with MEGADET® millisecond in-hole detonators
INTERDET® detonators are designed as a surface (inter-hole/interrow relay system, which enables an unlimited number of blastholes to be fired in sequence.
INTERDET® detonators are commonly used in conjunction with a delay detonator in every blasthole. The normal practice is for all the inhole detonators to have the same delay period and, as a result, the INTERDET® surface detonators control the firing sequence.
