Tank Electronic Reshef Fuzes
Tank Electronic Multi-Functional Fuze System
The TK128 is a sophisticated programmable Electronic Fuze system for main battle tanks against targets other than tanks. The TK128 is a multi-functional fuze system designed for 105mm guns. It includes communication capabilities with the fire control system of the tank.
105mm tank guns, for use with APAM ammunition. The TK128 is a multi-functional fuze system, that can provide rapid and lethal direct fires in support of assaulting infantry, penetrating bunkers and buildings with maximum resulting damage. It can destroy light armored vehicles, and also destroy helicopters for self-defence.
Automatic setting: Range data is derived from the fire control system of the tank, and then translated into the timesetting. This is then transmitted to the fuze, by the fuze-setter, through induction methods. Automatic setting system: Automated by the system fuze-setter, through receiving coil when fuze is set to “auto”. The data is kept in memory for a practically unlimited period of time, or until it is reset , generated by the fire control system, and transmitted by the fuze-setter. Manual Setting: Setting is performed on “range to target” data. Range indication is internally translated into time-setting. Manual setting system: Digital setting, positive self-locking by three setting rings.
The maximum range deviation of the fuze is 10m. The standard deviation of the delay error is less than 0.01 seconds (when on the automatic setting mode).
