New Fuze Solutions for new Mortar Systems

Introducing a new member of the JUNGHANS Fuze Family:
Optical Mortar Proximity Fuze PX581
The Optronic Mortar Proximity Fuze PX581 is independent of caliber and can be mounted on 60 mm, 81 mm and 120 mm shells without adjustments. Its optronic capabilities will allow no interference by electronic counter measures like for instance "Shortstop". Due to its special technology, the fuze functions highly precise at low ground distances and thus provides an optimal ammunition result. The necessary operating power is obtained from its own windwheel generator, which is also the second arming criteria. The fuze is equipped with a point detonation back-up system to avoid duds.
The DM581 is superior to conventional proximity fuzes, used in today's armed forces. It utilizes advanced laser-based distance measurement technology for target recognition. The optical fuze transmitter sends out light pulses at the rate of 500 pulses per second while the receiver constantly measures the distance from the target. The intelligent decision-making logic recognizes the target and detonates the shell at the programmed altitude and at the desired moment.
Optical modules are hermetically sealed and protected from temperature fluctuation to avoid condensation on the lenses. The fuze recognizes the ground surface but does not react to clouds, mist, snow or rain. Due to its very sophisticated optro-electronic measuring principle, it is not possile to interfere with any known counter methods.
Safety is ensured mechanically and electronically. A double bolt system and also the windwheel guarantee mechanical compliance with MIL-STD 1316. A sensor electronically secures the fuze on its trajectory path until the APEX is reached.
The PX581 is jointly produced by NOPTEL OY, Finland, and JUNGHANS Feinwerktechnik
